I would think it's funny if Brenda comes back and her secret is that she knows Jason has a son.

Brenda: Congratulations! I heard you have a boy.
Jason: What? Where did you hear I have a son?
Brenda: You are silly, Jason. My fiance said that he's a friend of yours.
Jason: Who?
Brenda: Franco!

That conversation was actually boring in my head too.
