Castiel's Gone Mad
A/N: Idea taken from the crew's commentary of the episode "The End", so if you haven't seen that episode don't read, and if you have listened to the commentary… DOUBLE POINTS!
I DON'T OWN ANYTHING
Dean let the wheelchair fall back to the dusty dirt coated floor. He scraped his hand roughly against his forehead; he held back the thought of Bobby's fate. Suddenly Dean was inspired to check Bobby's famous panic room. "Maybe him and Cass ran to the panic room, then they'll help me make since of this angel crap." Dean optimistically thought. He managed to find his among the clutter to the cellar steps. The one window in the basement let in fragments of light through the boards, barely allowing Dean to see the steps below his feet. He gently walked down the creaky steps, fearful of may be below. With even less light in the room he pulled his lighter out of his pocket and light the flame. "There must have been one helluva part down here." he forced a low chuckle. He gingerly stepped over the broken glass and what he hoped was red wine that caked the floor. He reached the panic room door, it was cracked slightly open. Dean waited in the silence for a moment before heard a familiar voice murmuring.
"God… dead…Bobby…died…" he pushed open the door slightly more, not wanting to draw too much attention on himself. He cocked his head through the door enough to see the rogue angel sitting with his back to the door. Dean heard a sickening crunching noise and then a small crackle of lighting, and then it repeated over and over. Dean listened this go on and on and until his curiosity got the better of him. He crepted along the dark sigil covered wall. Dean finally reached the right angle to see what Castiel was doing. He leaned forward as the lighting sound reoccurred. In between Cass's hands was a cockroach trying to scurry away. Castiel slammed his muck back down again on the poor insect, and again reviving it and slamming his fist down again. Dean's eyes widened with shock, he couldn't believe the once proud angel was sitting killing this roach.
"Hey Cass, Cass buddy." Dean reached out to touch Cass's shoulder. "Cass what's wrong? Where are Bobby and Sam?" Despite Dean's constant shaking Castiel didn't break from the task of killing and resuscitating the bug. "Damn it Cass." Dean said those all too familiar words under his breath. The man who stood up to one of the most powerful archangel (Raphael)
now sat in a corner, made as a hatter. Dean began to walk back to the heavy metal door and swung it open. He began to walk through when he forced himself to stop. "Cass," Dean called for the cationic angel still with no response, "…I don't if you're still in there… but I won't let become this. Not on my watch." Dean exited the doorway leaving Cass to continue his cycle, forever.
