J takes their hand and shakes it. Polite kid, huh.

He hears the surprise in Frisk's tune, and...yeah, he was a little too specific, huh. On one hand, he really should reel it in - he'd concealed his music sense too long to give the game away; on the other hand, if it helped with communication, it might be a good thing. Plus, evidently it was in the paperwork that got passed around between recruiters, so it's not exactly classified anymore. Heck, it might even help people out if they knew what he could do - to an extent, at least.

Well, Frisk seems to be rolling with it, at least. "Thanks. I've had a while to figure it out." He shrugs. "I'm happy to do the talkin' if it's easier on you."
