Castiel is my favorite charcter from the show Supernatural. He always wears his trench coat unless the character is his vesel, he's a fallen angel who rebels to help out Sam and Dean and God told all his angels to protect man, so that's what Cas does, Cas has more of a connection to Dean than Sam, that's why you may sometimes see the ship name Destiel some pronounce it (De-sti-el) Others pronounce it (Des-ti-el). Anyways xD if you don't know what Supernatural is it is a show with demons, spirits, vampires, werewolves, witches, and many more enemies/monsters that Sam and Dean fight, including Crowley (King of Hell), It's my favorite show :3 xD anyways I'm just trying to say: Enjoy the skin xo ~Budder
