Question: How is getting struck in the groin with a harpoon (with or without pulling the trigger) fatal?
Answer: It's also shown that Jason pulled the trigger. You never see exactly where the harpoon goes, so it could have gone into his torso. From the angle you see Jason spear him, though, it most likely went up and exited through his back. This could have hit vital organs and blood loss would also occur. Not to mention that the last you see of the victim he's screaming so Jason could have done more to kill him after the scene ended and the film moved on.
Question: What's going on with Tommy in the final scene when he's hugging Trish in the hospital? Is he possessed or what?
Chosen answer: He's not possessed. Dealing with Jason made him go crazy. In part 5, we find out he was in a mental hospital for a while, then gets sent to a home for troubled kids.
Question: When Gordon (the dog) went through the window, did he voluntarily jump through it because he was startled, or did Jason throw him out?
Answer: You can see from the inside of the house Gordon jumping through the window by himself. It shows him jumping on the table then through the window.
Question: How did Jason leave the hospital without anybody seeing him?
Answer: There was no-one to see him. Remember? After he murdered Axel and the nurse, they were the only two employees left in the building.
Question: At the end of Part 3, when we see the police taking Chris out of the cabin and to one of the squad cars, it's the middle of the day. At the beginning of this film, however, when we see the police taking the dead bodies out of the cabin, it's the middle of the night. What's going on here? Would it really have taken them that long to collect all the bodies?
Answer: It is my understanding that this is due to a complete lack of resources and/or manpower. Being that the location Higgins' Haven is located in is such a small podunk town, it would generally take more than a few hours to rustle up the required personnel to assist in such a mass cleanup of a massacre such as the one we were witness to.
Question: As Jason's body is being brought into the hospital, the camera focuses on a room with a crying girl, and presumably her parents, her face is obscured so who is this suppose to be? Is it suppose to be Chris from the last movie?
Answer: The way I look at it there's more than one possibility: 1. The crying relatives are totally unrelated, so to speak, to the events of the film. B) they are relatives of one of the victims, be it Andy or Debbie or Shelly. The girl does not look like Chris from part 3.
Answer: I suspect that the girl was intended to be Chris, hence her face being very obviously obscured (as Dana Kimmel did not return for this movie). The lack of a resemblance may be an error, though, with her face being away from the camera, it's not very noticeable.
Answer: The original idea for this one was Jason causing havoc in a hospital and I think Chris was supposed to come back, so your guess is as good as mine.
Chosen answer: You could easily die of shock/blood loss.
