YIIK with the update now makes it clear that Sami Pak isn't a friendly apparition who loves Alex after a brief encounter in an abandoned building and wants to be with him - she is instead a person who tragically goes missing and then inspires many others to waste their time in trying fruitlessly to rescue her or to bring justice to her death by combing the internet and doing amateur real life sleuthing. I would say that is about as respectful as you could hope to be to the real life Elisa Lamb case while also trying to tell the real story one of the developers writes about with being personally involved in the sort of internet sleuthing that did occur when Lamb actually did go missing and die.
