Castiel just rolled his eyes the slightest bit at that first comment, then watched Crowley pick up the puppy, pleased as well to see how healthy and content they seemed to be. Many things could have gone wrong, but all the puppies were alive, even the tiny one.

He shifted closer, reaching to set a hand on Growley's back for a minute as the dog paid attention to the littlest puppy, before turning his attention to Crowley at the demon's comment. "How would this have been my fault?"

Also how would Crowley have killed him, but that was another matter entirely.
