The Word of God was inscribed on a series of tablets that were dictated by God during creation "for the defense of mankind." Metatron is the angel who recorded God's word on a series of tablets. Crowley described Metatron as "The scribe... and suck-up. Took down God's word, picked up His cleaning." Metatron's personal note on the demon tablet reveals that there is a compendium of tablets about a variety of subjects, presumably on all the creatures that God created. Metatron disappeared after completing the tablets and encasing them in stone.
The first tablet in the series was excavated by Dick Roman from a dig site in Iran and describes how to kill the Leviathan using the bone of a righteous mortal washed in the blood of a fallen angel, the King of Hell, and an Alpha. Kevin is able to translate the tablet for Sam and Dean, but the leviathan Edgar kidnaps him and his mother and steals the tablet, delivering all three to Roman at SucroCorp. After Kevin is forced to translate it for him, Roman hides the tablet and sends Edgar to stop the Winchesters from assembling the necessary components. Despite his security measures, Sam and Dean complete the weapon and use it to kill Dick Roman, but the resulting explosion transports Castiel and Dean to Purgatory.
The second tablet was in the hands of Crowley and is titled "Demons." It includes instructions on how to construct a weapon against demons, information on how to see hellhounds, and most importantly how to seal the Gates of Hell by undertaking a series of trials.
Under torture by Crowley, the angel Samandriel reveals that there is also a tablet relating to angels. Castiel locates it with Dean's help in one of Lucifer's Crypts and goes on the run with it to protect it from all threats after the tablet frees him from Naomi's control. While Metatron states that it contains instructions on trials that, once completed, will seal Heaven, this turns out to be a ruse. Both the angel and demon tablets were in Sam and Dean's possession and they attempted to use the angel tablet to find a way to reverse what Metatron did. Their plans were cut short when Gadreel, possessing Sam, murdered Kevin Tran and made his escape with both tablets.
Metatron is able to tap into the power of the angel tablet to enhance his powers. This ends when Castiel smashes the tablet and imprisons Metatron.
Pretending to want to lead Castiel to his grace, Metatron takes him to a library where both the grace and the demon tablet are. While Castiel gets his grace back, Metatron incapacitates him with a spell and escapes with the demon tablet. Castiel later tracks Metatron down and retrieves the demon tablet from where Metatron had hidden it: under the mattress of his bed in his apartment.
Later, Sam and Dean recruit Donatello Redfield to translate the demon tablet to locate a spell capable of opening an inter-dimensional rift to make their way to Apocalypse World to save Mary and Jack. Due to his soullessness, the dark energy resonating within the tablet causes him to go mad and retaliate against the Winchesters, forcing Castiel to strip the spell from his mind, effectively leaving the mad prophet brain-dead. After acquiring the necessary ingredients for the spell, Sam, Dean, Cas, and Gabriel make their way to Apocalypse World and lead an exodus of humans into their world to prepare for a battle against Michael and his angelic armies.
After Jack dies due to his lack of grace, the Winchesters call in Lily Sunder and ask her to read Kevin's translations on the angel tablet in the hopes that it will contain something they can use to save Jack. The effort proves to be futile, but Lily offers another solution. Months later, after Donatello's mind is discovered trying to rebuild itself, Castiel is able to awaken him. Though Donatello remains soulless, he is no longer corrupted by the dark effects of the demon tablet on his mind.
While trying to defeat God Himself, Dean speculates that the very existence of the tablets suggests that God is not infallible and has a weakness. From Metatron's annotated notes on the demon tablet, the Winchesters and Castiel learn of a secret fear God has, one that He only shared with His favorite which is believed to be Michael.
The Leviathan tablet is the first tablet to be unearthed. It contains instructions on how to kill the Leviathans. The current location of the tablet remains unknown.
Charlie manages to get into Dick's office and download his emails. Back at her desk she sends these, along with the contents of Frank's hard drive, to the boys. She discovers that a package for Dick is arriving from an archaeological dig in Iran at a nearby airport and manages to send a fake email so it appears to be arriving 30 minutes later. This allows Sam and Dean time to get to the airport and switch the package for a case with a borax bomb in it.
When they open the case they find it contains a slab of red clay.
Dean cracks the stone containing the tablet. As he does so there are electrical storms, women go into labor, Kevin Tran becomes a prophet, and Castiel wakes from his comatose state. What can be read from the translation is the following:
"Cut off the head, and the body will flounder. Waste not thy time nor your breath upon the Leviathan herd. Point thy blade at the heart of their master, for from him springs all their messages. Leviathan cannot be slain but by a bone of a righteous mortal, as light and good as the Leviathan are hungry and dark, washed in the three bloods of the fallen: a fallen angel, the ruler of fallen humanity, and the father of fallen beasts."
After having captured Kevin Tran, Dick Roman forces him to translate the tablet for him. After the translation is done, Dick sends Edgar to kill the Alpha Vampire and get his blood, and summons Crowley into a devil's trap to make a deal with him.
At the same time, Bobby Singer figures out that the "ruler of fallen humanity" is Crowley and that for a "father of fallen beasts" they need an Alpha. Crowley is summoned and promises them his blood once they get the other needed pieces. Sam and Dean are able to get the Alpha Vampire to give them his blood after they save him from Edgar and prove that the Leviathans have betrayed him.
Sam and Dean steal the bone of a nun, Sister Mary Constant, to get the "bone of a righteous mortal", while Dick makes a deal with Crowley to have him give them the wrong blood. However, Crowley informs them of the deal and gives them the right blood and they are able to make the weapon the tablet describes. Dean is later able to use it to kill Dick Roman with the help of Castiel.
The demon tablet is the second tablet to be unearthed. According to Castiel, it was dictated sometime after Lucifer was imprisoned in the Cage. It contains sections on the demonic influence on the collective tapestry of the soul, and demonic transport to the regions of Hell. It also includes instructions on how to see hellhounds and how to destroy demons, as well as containing a number of spells, sigils, and protective circles that can be used against demons. The most notable spells on the demon tablet are instructions on how to close the Gates of Hell forever and how to create an interdimensional rift. It is currently in the Men of Letters Bunker.
After Crowley captures Kevin, he takes him to a warehouse where he shows him another Word of God tablet, this time about demons, and has him translate it for him. Kevin tells Crowley that it reveals how to throw open the gates to Hell and let demons out onto the Earth and directs him to one in Wisconsin while he performs a spell from the tablet to open it. However, Kevin casts another spell, this one from a section on how to kill demons, and kills two demons holding him prisoner and escapes. Kevin hides the tablet, but not before learning how to protect himself from demons and that there's a way to close the Gates of Hell forever and banish all demons from the Earth.
After it is stolen from the bus station where it was kept, Sam and Dean track the tablet to a pawn shop where it was sold to Beau. The tablet is then sold at an auction run by the god of greed, Plutus. Sam, Dean, Kevin, and Linda Tran team up to recover it while Crowley and the angel Samandriel also try to get it. When the bid doesn't get high enough, Plutus tries to sell Kevin as well. Eventually Mrs. Tran bids her soul and the tablet is sold to her, Sam, and Dean. However, Crowley possesses Mrs. Tran and teams up with Beau to betray and kill Plutus. In the fight that follows, Crowley, who learns of Sam and Dean's plan to close the Gates of Hell forever, gets his hands on the tablet and escapes.
In a desperate attempt to translate the tablet, Crowley abducts all future prophets, but none of them will possess the capability to read it until Kevin dies.
Linda Tran comes up with a plan to strike back against Crowley by hiring a witch named Delta Mendota to gather the ingredients they need for the "demon bomb" spell Kevin used to escape Crowley's henchmen. These ingredients are scattered all over the world. Delta brings them enough for at least one demon bomb but betrays them to Crowley, who kidnaps Kevin and leaves a demon to kill Linda. However, Linda captures the demon and takes him to Sam and Dean along with the ingredients and Kevin's notebook containing the information on how to create the bomb.
Crowley, even though he has all of the future prophets, prefers that Kevin translate the tablet for him rather than him having to kill Kevin and get one of the others to do it. After Crowley cuts off one of Kevin's fingers, he agrees. Kevin reads the titles of the various sections to Crowley, including the sections on how to kill demons and how to seal the Gates of Hell. However, Kevin also finds a note from Metatron, the writer of the tablet, stating that after he writes it, he plans to take his leave of God and his brethren and leave the tablets for humanity. This note reveals that there is a compendium of tablets, interesting Crowley with the fact that there are tablets on more things than demons and Leviathans.
Sam, Dean, and Castiel launch an attack on Crowley's warehouse to rescue the prophets and retrieve the tablet. During the rescue, Sam uses a demon bomb to kill three demons. Castiel confronts Crowley across a table that holds the tablet and when Castiel starts to use his powers on him, Crowley tries to grab the tablet and flee, but Castiel breaks it in half, leaving the escaped Crowley with one half and the Winchesters with the other. Sam and Dean decide to set out and find the remaining half of the tablet and Castiel chooses to join them.
Needing to deal with a lot of demons guarding the captive angel Samandriel, Dean and Castiel travel to Kevin Tran to get the ingredients for the demon bomb. Kevin, who is trying in vain to translate the half of the tablet he has, is annoyed with them and reveals how difficult just the first three ingredients would be to get. Castiel asks for a list and heads off to get them. Kevin is shown to be running himself into the ground trying to translate the tablet and is very disheveled.
When being tortured, Samandriel brings up the tablets, which is apparently hardwired into all angels, and specifically the demon tablet which Crowley is uninterested in as he already knows about it.
Castiel is able to get the needed ingredients, and during the assault on Crowley's headquarters, Sam and Dean are able to kill four demons with the bombs.
After weeks of non-stop work, Kevin finally manages to translate the part of the tablet about closing the Gates of Hell. According to Kevin, the tablet reveals that someone must do three trials and read an Enochian spell after each one. Kevin translates it as "whosoever chooses to undertake these tasks should fear not danger nor death nor getting your spine ripped out through your mouth for all eternity." Once the three tests are done, the gates can be closed. Kevin is only able to crack the first test which is to kill a hellhound and bathe in its blood. Sam and Dean set out to kill a hellhound by looking for someone who has made a deal which is to come due soon.
Later, Kevin finds information on hellhounds and calls Dean to tell him about it, telling him it reads "the dire creatures may be seen only by the damned or through an object scorched with holy fire." Using this information, Sam and Dean come up with the idea to use glasses scorched by holy fire to see the hellhound.
In the end, Sam manages to kill a hellhound with Ruby's knife and recites the invocation.
When Castiel is found by Sam and Dean looking for the angel tablet, under orders from Naomi he claims that his mission is actually to find Crowley's half of the demon tablet.
After finding the angel tablet, Dean asks Castiel if he is now going to go back to looking for the demon tablet like he'd earlier claimed, but under Naomi's orders, Castiel tries to kill him instead.
Kevin Tran calls Sam and Dean to tell them that along with Crowley apparently haunting his dreams, he has deciphered the second trial to close the Gates of Hell. Kevin reveals that Sam must rescue an innocent soul from Hell and "deliver it unto Heaven."
Becoming ever more paranoid, Kevin hides his half of the tablet while Crowley figures out what the Winchesters are up to as they got the "good half" and he got the half with useless information on it.
Sam is able to rescue the soul of Bobby Singer with help from rogue reaper Ajay and Benny Lafitte, but when he tries to release him to Heaven, Crowley intervenes and traps Bobby's soul, intending to take him back to Hell and prevent the completion of the trial. However, Naomi, wanting the trial to succeed, drives Crowley off and breaks his hold on Bobby's soul, allowing Bobby to ascend to Heaven and completing the second trial. Sam then casts the spell to signal the completion.
Having learned Kevin's location from Linda Tran's smartphone, Crowley captures Kevin and all of his notes on the tablet, leaving the Winchesters with no clues on the third trial and Crowley with everything Kevin has deciphered so far.
Kevin is captured by Crowley and held in an illusion of Garth's houseboat with all of his notes on the tablet. Two demons pretending to be Sam and Dean visit him with Crowley's half of the tablet to translate, claiming that they managed to get it from him. Kevin starts to work on translating the second half of the tablet, excited as it will hold the third trial.
At the same time, the real Sam and Dean receive a prerecorded message from Kevin with his notes and translations of his half of the tablet, sent in case something happened to him. While they are unable to figure out the notes any more than Kevin could, a symbol seen repeatedly in the notes ultimately leads them to Metatron, the angelic scribe who wrote the tablets in the first place.
Eventually, Kevin realizes that he has been captured and tricks the demons pretending to be Sam and Dean into thinking they are going after his half of the tablet while in reality he sends them into a devil's trap. Crowley confronts Kevin, who refuses to translate the tablet for him for real, saying he won't break this time and Crowley has no idea the power the tablet could give him. As Crowley now has the angel tablet he doesn't care and strangles Kevin, but Kevin is rescued by Metatron before Crowley kills him and takes with him the second half of the tablet.
At the casino where Metatron hides out, Kevin reveals Crowley's half of the tablet and tells Sam and Dean he has translated the third trial. Metatron reveals what it is and Kevin confirms it: they must cure a demon.
As Crowley is killing Sheriff Jody Mills, the Winchesters call him and he offers a deal to stop killing people they've saved: stop the trials and turn over the whole demon tablet. Dean agrees, but only if Crowley trades it for the angel tablet. In order to make the deal happen, Kevin digs up the first half of the tablet where he hid it, ironically under a sign depicting the Devil. Kevin puts the tablet back together and gives it to Sam and Dean. At the ruins of Singer Salvage Yard, Sam shows Crowley the demon tablet to prove he has it while Crowley shows off the angel tablet. However, the deal is a trap and they capture Crowley. Sam begins work on curing Crowley to complete the trials, but stops after Dean learns from Naomi what the tablet didn't reveal: the person that completes the trials will die as the ultimate sacrifice to seal the Gates of Hell.
While brainstorming on how to remove the Mark of Cain from Dean's arm, Castiel states that with the demon tablet they may have had a chance of finding a way, however, it's missing. Instead, they turn to Metatron for information.
After having his grace removed and turning human, Metatron reveals that he knows of no cure for the Mark of Cain and that the demon tablet doesn't contain information on it either. Castiel is able to tell that he is telling the truth.
Metatron leads Castiel to a library where he had another angel hide both the demon tablet and Castiel's grace. After leading Castiel along, Metatron incapacitates him with a spell and takes the demon tablet from its hiding place, stating that he can do a lot with it. Castiel gets his grace back, but is left worried by what Metatron will do with the demon tablet.
After being captured by Castiel, Metatron incorrectly believes that he wants the demon tablet and tells him he's hidden it where Castiel will never find it. Castiel just pulls it out of his coat and tells Metatron he'd hidden it under his bedbug-infested mattress and Castiel had gotten it back by getting his address from the TV station he works for and searching the apartment beforehand.
In an attempt to find a way into Apocalypse World, the Winchesters and Castiel bring the demon tablet before the Prophet Donatello Redfield in hopes that as a Word of God and with the angel tablet destroyed, the demon tablet will possess the spell they need to reach the alternate reality. Donatello is able to determine that the demon tablet does in fact possess the spell they need, but it and the ingredients are incredibly intricate. While researching the spell, Donatello is placed under the control of Asmodeus and instructed to let him know once Donatello decodes the spell.
Donatello is seen attempting to translate the tablet to recover the spell to open an interdimensional rift into Apocalypse World, all the while hearing voices whispering in Enochian as he decodes the text. While he eventually shows his translation of the spell to the Winchesters, it is later discovered that Donatello gave them a fake spell. They realize that since the soul of a prophet acts as a filter for the darkness within the tablets to prevent them from being driven insane, but because Donatello's soul was consumed by Amara, the dark energies within the tablet had corrupted him. Donatello tells Sam and Dean that he translated the whole tablet and that he doesn't want to fight what the tablet was doing to him or give them any information on the spell. He casts a suffocation spell on Dean to show off his newfound abilities. Castiel strips the spell from Donatello's mind, leaving him brain-dead and only kept alive through life support. Castiel reveals that the spell requires four major ingredients -- the grace of an archangel, a fruit from the tree of life, the Seal of Solomon, and the blood of a 'most holy man.'
As they wait for Gabriel's grace to recharge enough to reopen the portal, Sam tells Dean that Rowena is "boning up" on the demon tablet, possibly familiarizing herself with the spells inscribed on the tablet to prepare for their journey to Apocalypse World.
Searching for a way to defeat God, Dean brings Sam and Eileen Leahy the demon tablet. Dean suggests that the very existence of the tablets suggests that God is not infallible and there may be a way to defeat Him. Castiel brings a reluctant Donatello Redfield in to translate the tablet again and Donatello requests that they kill him if he goes insane again. Donatello finds Metatron's annotated notes where the Scribe appears to be trying to give context to God's actions. One states that "the Almighty guards His secret fear but it is always there. Fear of what, I do not know. This He shares only with His favorite." The Winchesters and Castiel realize that this likely means Michael since the tablet was dictated when Lucifer was cast down, but God takes control of Donatello and threatens to destroy everything that they care about if they carry on.
Refusing to stop, the Winchesters and Castiel, based on the information from the tablet, seek out Michael for help. After being convinced of the threat from his father, Michael provides them with the spell they need to trap God.
The angel tablet is the third tablet to be unearthed. It contains multiple spells, sigils, and protective circles that can be used against angels. It appears to contains angelic trials, though their purpose was not revealed. It also includes a second spell, personally placed by Metatron, that can banish all angels from Heaven and lock the gates. Metatron used the angel tablet to enhance his powers to make himself semi-equivalent to God. It was destroyed by Castiel to weaken Metatron and reclaim Heaven. Before his death, Kevin was able to translate the entire angel tablet into Proto-Elamite cuneiform. His translations remain in the Men of Letters Bunker.
Samandriel, who due to the spikes in his head has gone back to "factory settings," is tortured for anything useful that he knows. He speaks about the tablets which is apparently hardwired into all angels, and before Dean, Sam, and Castiel finally break in, reveals the existence of the angel tablet which interests Crowley who flees as the three break in.
After Samandriel reveals that he told Crowley about the tablet, Naomi forces Castiel to kill him for revealing its existence. When questioned, she calls Samandriel a traitor for revealing its existence as it is something that all angels would die to prevent demons from finding out about. Naomi reveals that like the demon tablet reveals how to seal all demons in Hell, the angel tablet may have something similar for angels on it.
After making sure he is completely under her control, Naomi sends Castiel after the angel tablet which Crowley is also searching for.
Having discovered that Lucifer had the angel tablet, Crowley starts searching for Lucifer's Crypts using Meg, who knows their locations from her time with Azazel. Meg only gives general locations of the crypts, so Crowley has his demons possess people who might know where they were located and searches for them while Castiel tortures and kills the demons responsible, trying to get the tablet for Naomi. Eventually after capturing a demon, she leads them to Meg who is able to show them the correct location of the crypt where the tablet is.
While Meg and Sam defend the outside of the building where the crypt is from Crowley and his minions, Dean and Castiel search the crypt itself. Castiel is able to locate the correct box containing the tablet as it is warded against angels and he tells Dean as he is the only one able to touch it. Dean finds the tablet encased in a rock similar to the Leviathan tablet and Castiel, on Naomi's orders, attacks him with an angel blade, trying to kill him to get the tablet. In the scuffle, the rock hits the ground and breaks, releasing the tablet. Eventually Castiel regains control over himself and when he picks up the tablet, it and he glow, severing his connection with Naomi and breaking her hold over him. After healing Dean, Castiel leaves with the tablet, telling Dean that all he knows is he must protect the tablet from Naomi, Crowley, and even Dean for some reason.
Both Naomi and Crowley meet up in the crypt, foiled in their efforts to get the tablet, but Naomi is happy as Castiel is protecting the tablet as he is meant to, even if it means protecting it from her. Castiel is later seen traveling on a bus through the countryside with the tablet.
Naomi, Ion, and Esper corner Castiel in a Biggerson's and demand the tablet. Castiel refuses to tell them where to look and Naomi has the other angels search all the Biggerson's for it, figuring Castiel hid it in one as he has been using them to hide. However, they are unable to find it and Crowley shows up, kills the other angel, and drives Naomi off. Crowley has realized that since the tablet freed Castiel's mind, he wouldn't risk being parted from it and has it inside him. After shooting Castiel in the gut, Crowley digs the tablet out of him and leaves with it when he receives word that Kevin Tran has figured out his deception.
When visiting Kevin in his illusion of Garth's houseboat, Crowley brings the tablet with him. He no longer cares that Kevin won't translate the demon tablet or help him as he has the angel tablet and this causes him to try to kill him before Metatron rescues him.
Metatron approaches Castiel to talk about the situation in Heaven. He's done some investigating and found many factions all at war trying to gain control and that Naomi leads just one of them. Castiel feels responsible after all the destruction he wrought in Heaven. Metatron invites Castiel to join him for some crepes at a restaurant in Ojai. He tells Castiel that he thinks they should close Heaven off from Earth to force the angels to sort out their issues, and also to prevent any of their conflict from causing damage on Earth. He says that the angel tablet contains trials which when completed will close Heaven. As the Scribe of God, Metatron knows them without the tablet. Metatron says he's just "a pencil pusher", but that Castiel is a warrior.
Castiel agrees to undertake the trials, even though Metatron warns that they will be more difficult than Castiel can imagine. He then points out Jane, the young woman who has been their waitress. Metatron reveals the first trial is to kill her and cut out her heart because she is Nephilim and considered an abomination. That night, the two angels trail her to kill her, but she reveals her knowledge of what they are and begs them not to kill her. As she is an innocent woman, Castiel hesitates, but when she attacks him and Metatron, Castiel kills her with his angel blade and completes the first trial.
While threatening the life of Sheriff Jody Mills, Crowley demands the demon tablet as part of his deal to stop killing people Sam and Dean have saved. Dean only agrees if Crowley gives them the angel tablet in exchange. Crowley agrees and they meet in Singer Salvage Yard to make the trade and seal the deal. Crowley shows that he did in fact bring the tablet after Sam shows the demon tablet and demands that Sam sign a giant contract to seal the deal. Dean pretends to examine the contract and gets close to Crowley to slap him with handcuffs with a binding link engraved on them, capturing him. With that, Sam and Dean take the angel tablet.
After learning that Castiel is attempting the trials to seal up Heaven, Dean brings the angel tablet to Kevin Tran to translate for the third hell trial while he and Castiel go to complete the second heaven trial -- getting the bow of a cupid. Kevin is reluctant, as he wants a normal life and it took him six months just to translate half of the demon tablet, but he agrees after Castiel gets rough with him. Dean and Castiel succeed when the Cupid is convinced to give her bow to them willingly, but Kevin calls and says that while he has found trials to close Heaven on the tablet, he doesn't see anything about killing a Nephilim or getting the bow of a Cupid. Naomi arrives and claims that she has learned from Metatron that he has been lying: he doesn't just want to seal Heaven, he also wants to expel all angels from it to Earth in revenge for being expelled himself. She earnestly tries to convince Castiel, but while Dean believes her, Castiel doesn't. Kevin, who heard the whole thing over the phone, is unable to confirm what Naomi said, but Metatron himself later does after impaling Naomi's head with her drill and capturing Castiel. He explains that these were never trials, but a spell used by God to cast out Lucifer. Before sending him back to Earth, Metatron steals Castiel's grace, as it is the last ingredient.
Dean asks Kevin to look over the angel tablet for the spell Metatron used to expel all angels from Heaven and a way to reverse it. When Dean later calls looking for Kevin to back up their cover story, Kevin is studying the tablet.
After Kevin starts to go crazy from reading the angel tablet, Dean drops him in Branson, Missouri, to give him a break.
Kevin has returned to the Bunker and begins once again translating the angel tablet.
Although Kevin finds it nearly impossible to translate the angel tablet into English, he is able to find an ancient codex in the Bunker that helps him translate the entire tablet into Proto-Elamite cuneiform, an extinct abstract language. Kevin finds a reference to fallen angels in the footnotes and Dean theorizes that the footnotes might contain Metatron's spell and how to reverse it. Ultimately, Sam and Kevin make a deal with Crowley: in exchange for translating the Elamite, Crowley will get to call Abaddon. After the call, Crowley keeps up his end of the deal, but learns from the writings that the spell is irreversible.
Kevin is seen attempting to read the entire angel tablet, but there was one section of the tablet that was almost indecipherable. He believed that when Metatron inscribed the angel tablet, he wanted to keep those specific words hidden, even from prophets. Using the tablet and an old Men of Letters book, Kevin and Dean discover a collection of sigils that can briefly hobble the possessing angel and return control to the vessel. Dean attempts to use these sigils on "Ezekiel" to tell Sam about the angel possessing him, but he catches on to their plan beforehand and alters the sigils in the storeroom to prevent the spell from incapacitating him. Gadreel takes the angel and demon tablets after killing Kevin Tran and telekinetically pinning Dean to a wall.
Gadreel delivers the angel and demon tablets to Metatron.
After Metatron is able to blow out a ring of holy fire with ease, Sam and Dean realize that he is using the angel tablet to gain great power.
Gadreel reveals that Metatron's great power comes from tapping into the angel tablet and that if they can break that connection, Metatron will just be a regular angel again and will then be able to be killed. Gadreel and Castiel try to sneak into Heaven to locate the tablet but they are tricked into Heaven's prison and trapped. After Gadreel sacrifices himself to get Castiel out, Castiel searches Metatron's office for the angel tablet, finally finding it in Metatron's typewriter. Castiel smashes the angel tablet into pieces, breaking Metatron's power.
In the Men of Letters Bunker, Metatron boasts about how he transcribed the angel tablet and knows all of the spells on it, suggesting that as a result, he can still help even in his powerless state. He later uses a sigil from the angel tablet against Amara, but it is ineffective.
The Kevin Tran from Apocalypse World enters the church where Michael is holding Lucifer with the angel tablet in hand. He explains that he was able to collect the elements annotated in the angel tablet to perform a rift opening spell which uses archangel grace as the primary ingredient, prompting Michael to siphon a portion of Lucifer's grace with his angel blade. With Lucifer's grace, Kevin is able to perform the spell. In the ensuing shock wave, Lucifer is able to free himself and use the rift to escape and return to Earth, sealing the rift behind him as the spell is designed to admit one person at a time.
Castiel tells the Winchesters about Lucifer and how he returned to the main reality using a spell the alternate Kevin got off of his angel tablet. With their angel tablet destroyed, the Winchesters bring the demon tablet to Donatello Redfield in the hopes that as another Word of God, it will contain the same spell as the angel tablet. Their hypothesis proves to be correct and Donatello discovers that the angel and demon tablets each contain a unique spell to enter another universe.
Kevin tells Mary that he was thrown in the dungeon when Lucifer escaped and was forced to perfect the spell to open the rift, which he was able to do. Michael is planning to visit a place in the south where the walls between worlds are thin and use a modified spell from the angel tablet to invade and conquer her world. However, this proves to be a lie and part of a trap that Michael has set for Jack to demoralize him.
In a desperate attempt to save Jack Kline, Sam calls in Lily Sunder and has her go over Kevin's notes on the angel tablet in the hopes that she can read them and find something useful. However, Lily proves unable to read the angel tablet translations. Dean says that only a prophet can read Kevin's translations and they can't ask Donatello due to his brain-dead state.
- In 7.20 The Girl with the Dungeons and Dragons Tattoo, the contents of the suitcase Sam and Dean stole from the leviathans was a hunk of red clay, but in 7.21 Reading Is Fundamental it appears as a gray stone before Dean breaks it open and recovers the leviathan tablet.
- In a deleted scene for 13.07 War of the Worlds its shown that the reason Michael never repeated the spell from the angel tablet is because Kevin didn't have enough ingredients to repeat the spell and they were almost impossible to find in the first place.
- The tablets have played a role in Seasons 7, 8, 9, 10, 11, 13, 14 and 15, albeit with the roles in Seasons 10, 11, and 14 being minor cameos. The tablets were especially prominent in the storylines of Seasons 8, 9, 13 and 15.
