'Supernatural' Season 9: Misha Collins to return as series regular, and direct an episode
Currently, Collins' character, Castiel, is embroiled in a major storyline -- he's just learned that a tablet exists that could banish all angels from earth forever, and Heaven is willing to do just about anything to keep the demons (and the Winchesters) from getting their hands on it. Naomi (Amanda Tapping) has been messing with his mind, and giving him orders that he only processes on an unconscious level.
We recently visited Collins on the "Supernatural" set, where we discussed whether or not Castiel is aware of Heaven's disturbing manipulation of his life.
"There's a fine line with Castiel. It's a little bit difficult to tell what's going on, how much he's conscious of," Collins says. "Castiel is being programmed by Naomi, and yet, it seems as though, largely, he's being programmed on an unconscious level. It's been a balancing act for me, deciphering how much he's aware of what's going on, and how much he's not. But he does take moments away to go ask her questions, so he's consciously communicating with her to an extent."
