[Actively avoids talking about it, actually. And unlike the rest of the residents at the time, Willow wasn't someone he really knew himself when she moved in; she was more a mutual friend through Ozpin than anything in the first couple months they lived together. He couldn't gauge how she'd react if he told her, and then the whole vampire incident just made him think that she wouldn't accept him at all. This is a kinder reaction than he'd expected, which makes it easier for him to continue to engage this conversation at all.

He shakes his head.]
