The look she casts him is more than a warning. If he's not careful, that cockiness will get his hide tanned.

She does take the first step, however. And, being a lady, she doesn't hem or haw about it. She moves the full distance across the room, regardless of whether or not Tommy starts on his end of the deal. It just so happens that right around the middle of the room is that chest at the foot of her bed, and Kate gracefully climbs atop it.

It's her turn to have the high ground.

(And, judging by the self-satisfied smirk hanging off her lips, she's not about to relinquish it. Tommy's just going to have to brace himself to take his kiss like lady.)
