"He is a bit of a worrywart, isn't he?" Nikki calls back with a grin and no hostility to speak of it. He almost sounds sympathetic. The kid seems a little like a stick in the mud, though he's got enough self-awareness to realize it's probably partly out of awkwardness and partly because Nikki himself inspires that sort of wariness from most people he's met. Nikki knows he's a lot but, well... That's just how he is. Like he told Zeke before, he has his own way of doing things and has no intention of changing that for others.

"Oooh, I see!" Nikki snaps his fingers. "There's no time like the present to learn how to get in and out of places you're not meant to be! ... Though that's something you definitely didn't hear from me!"

Once he hops to his feet, he looks around for a second before turning his attention to Tsukasa to ask at normal, conversational volume; "So, cool twin, what brings you to this shindig anyway?"
