That's right. Everyone hates you.
But I love you. You're MINE.
[He's rubbing slowly at Cain's back like he's trying to get a drooling idiot infant to fucking spit up already and be done with it, which isn't too far from the truth of the situation.]
And well, you hurt my feelings quite a bit, not listening to me like that. [pet. stoke. pat.] But I know you're sorry, and you're going to try harder to make me happy in the future, and you're never going to do that again. Because I love you.
[He pulls back, smiling, gentle, keeping the sardonic sounds out of his voice as best as he can.]
