It never made sense how he found Alice

Him being able to find her like that and travel to her home doesn't really seem like something Jason can do, especially in later movies. What did he do, ask around town about her?

I think they were winging it without any long term vision of what Jason or these movies would become, so when they created that scene they didn't have a clear concept of who Jason was yet.

The filmmakers probably didn't imagine a generation obsessed with literalism.

In 1981 no one asked questions

She did say she had to get her life back together...Meaning she went back to Blairstown

He used Mother's head and the blood of the other victims to do a locator spell, duh

It doesn't make sense but it's still kind of cool. Though it really doesn't make sense how he was able to sneak in while she was asleep and put his mother's head in the fridge. Also a moral lesson. If you fear someone is going to kill you get a big dog. Not a cat.

1981...He looked in a phone book.


Or maybe the camp had records of employee info.

Finally a plot hole has been discovered within the Friday the 13th movie universe. Good job
