Status Updates From Horror Movie

I get the point of having no motive for how the teens were treating the Thin Kid as part of the horror. But I don’t understand Valentina as a character. She’s so cruel to the person behind Thin Kid for no reason and it’s annoying me to the point of questioning the whole point of the story because I’m almost halfway there and there’s really no plot to this yet.

Flashbacks + remaking the movie. That’s it.
