I haven't had my own room. Ever. I'm making this awesome. I've got my kickass vinyl. I've got this killer mattress. Memory foam -- it remembers me! And it's clean, too. There's no funky smell. There are no creepy motel stains.
Inside Dean's Bedroom
Dean's bedroom is located in Room 11 in the Men of Letters Bunker. Dean takes great delight in decorating his bedroom, adorning it with his weapons on the wall, including the axe he found in Purgatory. He places a photo of his mother and him, which he always carried in his wallet, on the desk. He starts building a vinyl collection along with the records left by the Men of Letters, which includes Howard McGhee, Vol. 2, and Nat King Cole Sings for Two in Love. Dean has also bought a memory foam mattress for the bed.
People who have been in Dean's room:
Charlie and Dean search his bedroom for the Key to Oz, where Charlie comments on his meticulously organized porn collection. Dean finds the key, though the Wicked Witch appears and lobs a blast at Dean, prompting Charlie to jump in front of it. When Dean finds that the blast killed Charlie, he quickly urges Ezekiel to take over Sam and return Charlie to life.
Dean is laying on his bed and listening to music through headphones, when he yells Sam's name. While the lights flicker, Sam, in a panic, searches the Bunker looking for Dean. As a ghostly figure appears behind Sam, Dean shoots it with a salt round and announces that the Bunker is haunted.
While Sam attempts to summon Crowley, Crowley is already in the Bunker and in Dean's room. He says that he didn't know the full extent of the Mark of Cain. He does say that he omitted to tell Dean that Cain also did not want to become the killer the Mark was making him -- so he stabbed himself with the First Blade. It didn't kill him because the Mark wouldn't let him die. Crowley puts the Blade into Dean's hand. He tells Dean that he's feeling a new kind of life and tells him to open his eyes. He tells Dean he will now see what he sees, and feel what he feels. After a moment, Dean opens his eyes: he has become a Knight.
While trying to decompress during Dean's cure, Sam goes to Dean's bedroom, where he has left it as it was, litterd with Busty Asian Beauties magazines and pie. After he is cured, Sam leaves to get Dean some food, while Castiel checks on how Dean is doing. Dean confides that he worries that Sam will leave, but Cas encourages Dean and stresses to him that the brotherly bond is strong between Sam and Dean. He also encourages Dean take some time off to heal.
At the Bunker, Dean sits at the edge of his bed, still recovering from the massacre he had committed back at Randy's house.
In the Bunker, a worried Dean sits in his room researching the Mark of Cain. Sam enters with the news that he's caught a case. Dean wants Sam to check it out, but Sam tells Dean that he needs to get back in the game instead of locking himself away; Sam knows that Dean can beat this. Bolstered by Sam's confidence, Dean agrees.
While they’re having their beers, Sam apologizes to Dean for not looking for him when he was in Purgatory. Dean shakes it off, saying that the important thing is that they’re together now. Right before he goes to bed, Sam asks Dean why the banshee went for him, if it only goes after the vulnerable. Dean lightly answers that the banshee saw his golden blade and decided to attack him instead of Mildred Baker. Sam shrugs and accepts this explanation, but later that night Dean is unable to sleep. He is left sitting on his bed with his head in his hands, obviously troubled by his thoughts.
As Amara gains entry into the Bunker by removing the warding sigils, she is dismayed to find that Chuck is not there. As she explores the Bunker, she comes to Dean's bedroom; entering it she finds a framed photo of a young Dean and Mary and looks at it fondly.
As the British Men of Letters are cataloging and searching the Bunker, Mr. Ketch makes his way to Dean's room in search of the the Colt, where he finds his Busty Asian Beauties, and takes a photo of Young Dean and Mary from Dean's drawer.
Dean heads into his room to remove the rest of Michael's clothes when he notices two scars on his shoulder.
Dean hides out in his room, which he hasn't left in a week. He's been spending his time eating junk food and watching horror movies on Shocker TV. When Sam comes to bring Dean a case, Dean is excited as it involves Panthro from ThunderCats.
