Misha Collins has become accustomed to Castiel changing forms on Supernatural — from good to bad to God to good again. But teasing his various transformations — like the one fans will see in tonight’s episode — without giving too much away still proves a daunting task.
“He’s different and he’s got some different qualities. I don’t know how many times over the past years I’ve had to tease stuff like that, but there you go. He’s different again,” jokes Collins.
Yet, though his various states of unrest have become par for the course over his run, Collins says there hasn’t been anything quite like this, as the angel deals with processing the psychic injuries that he inherited from Sam two episodes ago. And it’s not easy. In fact, says Collins, Castiel is in “a very deep state of denial” regarding the flood of memories and thoughts that rendered Sam unable to function not long ago, and he says, “that manifests itself in a very schizophrenic manner.”
