He doesn't mean to laugh at Klaus-- well, not intentionally. Just the mental image of that caught him off guard. When he quiets though, there's a pleased little hum that leaves his lips at the brush of lips. He inclines his head a little, enough to let his own graze over Klaus' forehead as he contents himself with drawing his hand up his back.

It's surprisingly meant as a soothing gesture and not much else. It's just nice to have a warm body next to his, be comfortable enough with someone you can have a laugh. Shit, it's not a luxury he always has much anymore. "So I'm guessing you're spending the night right here, huh?"
