'Dean looks up at him blearily as Castiel pulls down his mask. He smiles down at the pup and back up to Cas and hoarsely says, “Hey, Cas. Look what I made.”
Castiel chuckles, but his gaze falls to the tiny, pink infant in Dean’s grip. He’s birthed plenty of pups before, but never has he felt such a wash of emotion at the sight of one.'
