Ears would be totally cute but the Eyes player went quiet :(
I still don't have any Bravos yet, but I have a Foxtrot who'd sleep on the same floor as him, named thereaper. Helena would be nice to him. And of course, just because someone's not on the same team doesn't mean they couldn't interact, which brings me to...
Blitz smoothasglass was also turned in by an ex-lover and I think they could have bonded over that. He likes making friends, anyway, and will have spent a little too much time trying to see if he could sneak up on Charlie using his speed or something. (And probably failing.)
Livewire here is probably going to annoy the piss out of Charlie. She's very likely to hit on him, but more importantly, she's very much not quiet. Sorry about your sensitive hearing, Bat. She'll also try to convince him to use his sound mimicry for pranking purposes, like some kind of party trick. At least he can hear her coming to avoid her?
