Appears BigDreams had her mobile # at one point. I have to wonder if they ever talked beyond texting or what.

I'd posted in there links to people who claimed to know her, her cousin (the aforementioned Emma) and a friend, named HermioniesHippos. Goes along with the HP theme, so possibly another alter.

To be completely honest, I really, really hope that none of her stories on here were fabricated. That would be so, so shitty.
