Billie doesn't like going in for heroics when she can help it but sometimes you just have to be a good person, right? She's quick, she can get places others can't in the blink of an eye, and that's why it's her who does just that almost immediately next to Christine once she ends up with someone needing a healer on hand.

Or more like in arm, considering she's hauling a little cat-like beastling kid around in both of them.

It's mostly a coincidence that Christine is the first healer that someone mentions to her when she asks, pointing her that way and telling her to hurry up. Hurrying entails Blinking, which means one moment, Christine is either alone or wrapping up her current work and, the next, she has a someone in what might be a familiar red coat (but also a very unfamiliar mask) popping into existence with the aforementioned kid in tow. Conscious, thankfully, if dazed and bleeding from a cut on the head.

"Hey, you're one of the healers, right?"
