The insanity seems to free Castiel of some of his guilt, though it leaves his mind scattered. He is now unwilling to fight due to his belief that he is a 'jinx', though Dean convinces him to help kill Dick Roman. He also expresses some fondness for [[Meg]] despite the previous animosity that existed between them. However, after getting trapped in [[Purgatory]], Castiel seems to have regained his sanity though he admits there is no way to know for sure. However, his experiences have changed his personality somewhat and he is no longer as aloof as he usually is and has displayed a fondness for human things he took for granted such as watching television, which he never understood before.
==Castiel Trivia==
* Castiel's name is first mentioned in the Season 3 episode [[3.06 Red Sky at Morning]] during the graveyard scene where Sam reads aloud a summoning ritual from his [[John Winchester|father]]'s journal. He speaks the names of several angels during the ritual, and one of them is Castiel.
* [[Misha Collins]] reports that "Kripke wanted to base the look of the character on the comic book character ‘Constantine’" [http://eclipsemagazine.com/hollywood-insider/6692/hollywood-insidersupernatural%E2%80%99s-angel-of-thursday-%E2%80%93-chatting-with-misha-collins-about-castiel/ Source].
* There was great secrecy around the introduction of the character. When the role was being cast it was advertised as being for a demon. It was only at the audition that Misha found out Castiel was an Angel. [http://www.scribd.com/doc/3641762/Castiel Read the casting sides for Castiel.]
* [[Mark Pellegrino]] who plays [[Lucifer]] also auditioned for the role of Castiel.
* Dean first refers to Castiel as "Cas" in [[4.04 Metamorphosis]]. The nickname is subsequently used by Sam and Anna then [[Uriel]] as well; later several characters refer to him by the nickname, e.g. [[Ellen Harvelle]].
* The show's writers spell the nickname "Cass" [http://www.scribd.com/doc/73893258/The-Rapture-Network-Draft source]. In fandom, and particularly in [[Fanfiction]] it is almost exclusively spelled "Cas".
* On the [[Season 4 DVD]] the English subtitles call him "Cass" and other times it's "Cas".
* According to [http://www.ascension-research.org/davidson.html "A Dictionary of Angels: Including the Fallen Angels"](ISBN-13: 978-0029070529), Castiel is an Angel Of Thursday in the occult lore. This may be a reference to the fact that Supernatural aired on Thursday nights on The CW when the character was introduced. Crowley refers to Cas as "The Angel of Thursday" in [[6.20 The Man Who Would Be King]]. He also comments that it isn't Castiel's day; this may refer to the show having been moved to Fridays.
* There is a municipality in Switzerland called Castiel. Its coat of arms is Saint George killing a dragon. It looks similar to Michael fighting a dragon. This image has appeared in paintings in [[2.13 Houses of the Holy]] and [[4.22 Lucifer Rising]].

== Appearances ==
Outside, Castiel tries to comfort Samandiriel, telling him he is going to take him back to Heaven, but Samandiriel is frightened as he revealed major angel secrets under torture. Samandiriel realizes Naomi is controlling Castiel and tries to warn him, but after learning that Samandiriel revealed the existence of the angel [[The Word of God|Word of God]] tablet to Crowley, Naomi orders Castiel to kill him. With no other choice, Castiel draws his sword and stabs Samandiriel, killing him. Castiel is horrified that he murdered another angel, but Naomi calls Samandiriel a traitor and Castiel a hero, explaining that the angel tablet's existence is a secret any angel would die to protect, including her and it has the potential to cause great harm if it falls into Crowley's hands as it could potentially be used to seal all angels inside Heaven. On Naomi's orders, Castiel claims Samandiriel was corrupted by Crowley and he was forced to kill him in self-defense and that he will be taking him to Heaven to be put to rest (in reality so Naomi can determine just how much he broke). However, his odd behavior and the fact that his eye starts bleeding before he leaves draws the Winchesters' suspicions that he is possibly being controlled.
