As usual, he's very conscious of her leaning into him so intimately, and the hand at her waist gently encourages her to nestle in just as close as she likes. After all, it's a pretty tame show of affection--at least, to anyone who can't effortlessly read how thrilling and heartwarming it is to him, and how much he notices how warm and soft she is.

Not that it takes psychometry or telepathy to tell he's head over heels for her.

He follows along with her tugging him into the elevator, and laughs a little with (obviously pleased) surprise when she casually leans right up against him again. His arms slip loosely about her waist, and he nuzzles into her hair a little, chuckling at that callback to when they reunited. It's a little bewildering to think she's seriously suggesting what had been just a stray thought. Not that things hadn't progressed way past that point already--she'd already made real some other stray thoughts that went much farther--but somehow it underscores the reality of their relationship, and he can't help but grin and hold her a little tighter.

"...I, uh... yeah, that uh, that does sound pretty good..."

...never mind that he's not sure where they could go that wouldn't strike him as romantic just because of her being there with him.
