Frankly, I do not think Sammy is "closely based on Elisa Lam". Her disappearance being in an elevator was inspired by Elisa Lam's disappearance as the internet very unhealthily obsessed over that video for a very long time, and in places still kind of do. An immensely distasteful documentary about it JUST came out on Netflix like a couple years ago. I think that is sort of it, and you seem to be misinterpreting some shit Andrew said.
