Kaidan's been operating on the theory that if he's willing to dance with everyone, it's less noticeable when he wants to take anyone specific out onto the floor, away from easy eavesdropping. His fellow exotics, particularly the new arrivals (willing or not) are the real reason he's been circulating, in robes and face paint that are practically restrained by comparison with their hosts.

His invitation being answered with a flat stare knocks him off his game momentarily, and he barely checks his instinct to rub at one temple (and thus smear the paint) before offering that "Hey, look, I won't be offended if you say no, but dancing lets them file us away into a category they understand." A pause to reflect returns the observation that he may need to explain himself a bit more, which he does with a "Makes it easier to talk freely. My name's Kaidan, I've been here about a month, now."
