I rly wonder what the symbol of the girl is… so is she a ghost or not..? From the context it really just seems like they’re keeping that girl hostage in a basement bc why would they say that right after MC confronted them?? But also the girl looks insanely like the MC so could it be a sign to gtfo? Y’all I’m invested
