After shifting Sam’s hallucinations and trauma to himself, Castiel takes on a heavy burden. One that messes him up irreparably. One might call him crazy, it is how he landed himself in the psych ward Sam had been in.

Crazy Cas was a little different from crazy Sam though. He was tired no doubt and certainly didn’t enjoy the Lucifer hallucinations—but the tiredness made him a bit loopy, and Luci had been a brother at one point.

Castiel was…deranged. In the weirdest of ways.

You, Sam and Dean, go to visit him. You are shown to his room, and slowly open the door and Cas slowly turns around. He looks happy to see you. Before you can get out a ‘hi’ or ‘hello’ or ‘how are you?’

“Pull my finger.” The angel sticks out his index finger with a giddy little smile, Dean says “What?” And Castiel insists with a little bob of his head up and down, “Pull it.”

You do. The bright ceiling light explodes overhead, glass hitting the ground with a clatter.

Cas grins ear to ear, “Heh heh…” He giggles childishly in that naturally low octave and sways a bit before pulling you three into a hug.

Wow. Never ever in your life did you think you’d see Castiel ‘Warrior of Heaven’ like this.
