If he'd been alive -- or, would be alive? Timelines were confusing -- by the time Meg realizes her epic unicorn love for Castiel, he would have written it. However, there was that pesky 'Only one prophet allowed at a time' rule and, well. Kevin had called dibs. Her love story will have to remain unwritten.

But Meg kisses him again and you know what he's only human, okay? Especially at the current moment, with the the whole lack of powers deal. There's only so much he can take when a woman has pushed him up against the wall and is repeatedly kissing him.

And so Chuck kisses her back. After all, she's just as human as he is, currently. He doesn't have that much to lose, and makeouts to gain. Even if she is a demon.
