The weirder thing is how into the diary she was, which then made the ghost sex weird by association. If she just learned it was a family sex ghost and rolled with it, totally fine.
Also I know it’s just storytelling/scriptwriting bs but it’s SO weird that the first proper beat of the episode is her SAYING THIS SHIT.
Yeah! It's like, how good of a writer was grandma? Was it really the writing or was the "ghost" leaving some kind of "psychic imprint" on the journal? It's only ever implied, and vaguely. It's such a bad episode, I can't help but love it.
