Jason Goes to Hell: The Final Friday (1993)

Visible crew/equipment: In the finale, Jessica runs over to Jason from behind and she stabs him in the heart with the dagger. Then, Jason lashes back and hits Jessica, and she goes flying backwards. Absolutely anyone can see the large blue crash mat that she lands on (cropped/edited out in some versions). (01:20:25)

Steven Freeman: Duke! The part about being reborn through a Voorhees woman, does it have to be a living woman?
Creighton Duke: No.
Steven Freeman: Duke, that thing is in the basement with Jessica's dead mother.
Creighton Duke: Holy mother of God.

Trivia: When Steven is in Jason's house, we see the "Necronomicon", or "Book of the Dead" from the "Evil Dead" movies. He even picks up the book and flips through it. The director has said this is because Jason is a deadite, as his mother made a pact with the devil to bring him back from the dead.

Question: Who is Jason's father?
