Friday the 13th: The Final Chapter (1984)

Revealing mistake: Trish jumps out the window and lands face up on the ground. You can plainly see it's Kimberly Beck's stunt double. She looks nothing like her. (01:21:35)

Jimmy: Ted. I think... I think when we get to town I should call Betty.
Ted: Jimbo, calling Betty is definitely a dead fuck thing to do. Look, first rule of love: never get rejected by the same girl twice. I mean, that's useless. If you want to make a fool out of yourself, always do it with someone new.
Jimmy: I don't know anyone new.
Ted: Well, sex is a great way to meet them.

Trivia: When Judie Aronson, who plays Samantha, was filming the scene in the raft where she gets killed, they were doing so many takes. She was wet and cold and wanted to warm up. The director refused until he got the shot he wanted which made Judie cry and freak out. Ted White, who played Jason, was so upset about this that he demanded they get her a blanket and let her get warmed up or he would walk off the set and not come back. Needless to say, Judie got warmed up very quickly.

Question: What happens to Tommy and Trish's mom? We never see what happens to her after something startles her outside.
