Honestly, there's a part of Alice that had probably been wondering about that - not after everyone left, since her mind quickly went to total static and hallucinations the moment the train tried to re-enter the void over and over, but during the moment where everyone left? Alice sure did worry a bit about the kind of situation the other girl ended up in.

.. then again, the girl hasn't mentioned a thing about her own situation, so maybe she was okay back home.

Alice fiercely hopes so, anyway. This girl deserves so much better.

"I would if it was that easy."

There's zero hesitation in that answer. Of course Alice wants revenge. Taking revenge is basically all she's been doing back home too. It's what she lives for.

"But as we know, there is very little I can do against that damn train." Not even watching the bad words in front of the little ones anymore!

That's how you can tell Alice is Done, clearly.
