Oh. Okay, that's...something new. He's never seen Nida blush before, and it's....okay, it's really compelling. It's adorable, is what it is, and so is the way Nida drops his face to try and hide it, the way he runs his fingers through his hair the way Billy knows he only does when he's nervous. Nervous, who would have thought? Here he is, just this totally unsmooth nerd from New York, managing to make Nida, Mr. Professional Spy and Seducer of Men, blush. He can't help but feel a little proud of that fact, even as he feels his stomach do a weird little flip, and he resists the urge to...to what? To reach out, maybe, and tilt Nida's head back up so he can really see that blush. To...he doesn't know. Whatever. It's only fair, right? For how many times Nida's made him blush, paying him all those compliments. But still...it's a heady feeling, and he's going to savor it, even if it feels selfish. Even if he maybe shouldn't.

He's still staring, isn't he? Whoops. At Nida's offer, Billy shakes his head, blinking and looking down, too, his hand finally (reluctantly) sliding off of Nida's. "Uh, yeah." If he sounds a little distracted, it's because he is. "Yeah, that sounds great. I can go steal us a couple of chairs somewhere out of the way, maybe? And we can...plan out a time to hang out again. Just us. For lessons." Lessons, and hanging out. And that's all. Really. God, what is with him tonight?
