"Oh, really?" He gives his best attempt at a villainous laugh, and it's not so bad, he could totally take over the world if he wanted to, no big deal. "You know that's basically an invitation for me to dip you and start a heavy make-out session in like, the middle of a double date or something in front of your pals, right? Because I just want to make sure we're on the same page before it actually happens, little bit of front row action never hurt anybody."

He's joking, of course. Kind of, in a way, maybe. It's not like he hasn't already talked Chuck and Sawyer and even Derek's, to a certain extent, ears off about her, plus they've all met Kate now and it hasn't been remotely difficult for them to understand why he likes her so much. He suspects some extended kissing action would phase any of them all too terribly, though he's then only one of them with a significant other--ha, how is that even a thing that happened--so he doesn't really have any qualms about making them envious. He's not sure whether that makes him a bad friend or just a super excitable boyfriend. Not that the two are mutually exclusive.

"Anyway, maybe we ought to practice some more because the grosser the better, right?"
