Theresa Gelbman, from "Happy Death Day"

Tree is an answer to the question "what if the mean girl and the final girl were the same girl?"

In the first greeting, if you want to see her freak out, tell her it's September 18th. That should also put you in the next iteration of her strange story. Or if you want to see her less panicked (but maybe with some PTSD), tell her she has a copy of yesterday's newspaper.
