I've been binge-watching F13 for a podcast, and also because I love the series. I browse here every so often to look at factoids and such, and I noticed something on the Timeline article that's on this page. According to it, Jason Lives takes place in 1990, and that Tommy Jarvis is 18 years old.(Kinda weird, but I'll bite.) Yet according to the page on A New Beginning, the film takes place in 1985, and that Tommy is 17.. So how did Tommy age once in five years?
