The response from the poltergeist is for the pen to bounce in the air, like it's being waved about.
Sephiroth makes a thoughtful sound before turning, moving to lean more comfortably against the kitchen counter as he considers. "It's a shame I've always been terrible at naming things." Sadly that's not quite a joke, but it also doesn't mean that he's unwilling to try.
"Hm, ought I be thinking of something considered sex- and gender-neutral? Adrian, perhaps? Or something a bit more controversial like Michael?" He's smiling ever so lightly with a touch of amusement. Then again--
"Wait, hold on." The poltergeist had had trouble writing, after all. Retrieving another piece of paper, he wrote down the names as he spoke them, "Adrian, Alex, Michael, and Chris, to start. Cross out what you don't like?" It was a little convoluted and likely to be a long process, but he supposed there was time enough.
