If it means not bringing more trouble down on their head for a little while longer, Billie will do what she can for Red, regardless of doom.

"Maybe, but then you have a tiny dragon running around in the city." As a cat, sure, but only as far as the eye can see. If it fails, an upset over someone spotting Red trying to, well, she doesn't know, raid a trash can or something isn't as funny as it sounds. "And I know. I have time to work that out, though. Upper limit might be a hippogriff. After that, you run out of tame animals people won't bat an eye at."

She shifts how she leans on the railing just enough to watch the cat and Mercy, too, though now that Mercy is eyeing the cat, the little puffball with wings freezes, staring back. Maybe it thinks if it holds still enough, Mercy will forget that it's there.
