Day by day you were more suspicious of Castiel. He had been in and out of the bunker going off to who knows where. He was acting…like an exaggerated version of himself.

Like someone was acting him out.

The octave of his voice felt weirdly forced, his eyes would narrow more than usual, he seemed more repulsed than fascinated with humans.

You’re in the bunker’s library, reading up on angels since you’re curiosity got the better of you. Lucifer could tell you were getting suspicious.

He didn’t want his cover blown. It was oh so fun having a brand new vessel to rule Hell with. He didn’t want that all ruined by one pesky skeptic.

He materialized behind you—with an urge to say ‘Boo.’ but he settled for a monotonous rumble of ”Hello.” Castiel would say something like that, right?

He was trying to decieve you after all.
