[That's not a question she expected, blinking at him for a moment before looking down.]

Oh, well, it is. White's just a nickname my dad gave me when I was younger to match with the one he gave my brother, Black. It's a whiskey.

[... But that's not why she goes by it.]

After Mom and Dad started letting us go places with them on League business, my brother and I decided that we'd use them as aliases since everyone else had them too. It stuck after they died and I was kept in the hospital so the League wouldn't be able to find traces of me, or so Black told me when I found out the whole... me dying thing, but up until then I'd just thought it was because we were the only Casters left in our family -- even if I didn't have any powers of my own, my family still accepted me as part of that.

[Their love really is a curse, but it's still warming up nicely despite her thoughts.]

I guess I don't really have any reason to use it here, but it's just habit, I guess. You can call me Mary if you want.
