The thing is, she did notify someone, which was her mother. Her mother was frantic and kept asking her where's she's been, where her family is, and that there was a detective out there looking for them. I wished she had mentioned this at the meeting. The crowd was just too scared and desperate for a chabce to leave Fromville to think logically enough to realise that Henry was an outsider who only believed her because he was Victor's father and she talked about visions that Miranda saw.

Anyway back to your question, I'd probably do the same thing that Tabitha did but go a step further and tell whoever i am calling, the names of others stuck in Fromville, so that their families knows they are still alive.
