I had thought at the end of the penultimate episode that Bobby wasn't actually bobby when they left the warehouse, but I think Dick shooting him and then the events of the ensuing episode shot that idea down.
That actually makes sense. Castiel's essence needs a new vessel, and he incorporates Bobby's psyche in there somehow?
