She had stayed away from the water, she had tried to ignore the sound, that endless humming from the river, but all it ever needed was one weak spot to latch onto — laughably enough, that same weak spot has finally shown up, every doubt in her head turning the corner into the alley, saying her name.

Billie doesn't give much more of a reaction than moving her head, turning it just enough to stare at him with one beady rat eye, trying to keep track of where he is as he fades in and out of sight with the cloak falling around his form. That she reacted to her name at all may betray some comprehension but how much exactly, it's hard to tell in this state. It could be enough to recognize him, it could be she's only reacting to someone, anyone at all, approaching her, but there's no immediate rush to violence, not yet. If anything, the sheer lack of reaction could be construed as reserving that energy for something else.
