Don't worry hun, she snaps and decides to feed herself to a demon by just walking on in there, expecting for it to go the same way that it did for her sister (it doesn't)

Ah, I didn't realize that another chapter came out and the sister is still alive (she's just really messed up and idk if she'll live or not)
