"He had help. None of them were doing well at the time." It almost sounds a little defensive, but he feels it's warranted. Lucifer already hates Castiel and he doesn't want something he said to be added to that pile. He is not looking forward to attempting to balance this angel complication.

The pillow actually manages to full out hit his face because he didn't see it coming. Or expect that would happen. So he startles and looks at him. "Are you twelve?" Istredd looks stern for all of two seconds before he laughs and hits Lucifer back with it. But he doesn't throw it, he keeps a hand on it, it is his pillow now. His weapon.
