Question: When the detective is opening the hidden door in the floor, he looks over to a syringe that is laying on the floor. The safe is also shown as open. How is the safe open? Why is the syringe in the floor? Why didn't anyone use the syringe? Was the syringe full?
Answer: Since he was still only a teenager, it's likely he would have left the experience traumatized and needing help. At the end of the day, I don't think Daniel woke up thinking he was gonna take someone's life. In The Scott Tibbs Documentary, after Adam's disappearance (the bathroom game in Saw), Scott Tibbs nearly manages to interview Daniel against his will, but is stopped by security.
Answer: From an article on the Saw-wiki: After being found and rescued by his father's fellow officers, Daniel was taken to the Saint Andrews Hospital to recover. During his stay, Daniel was nearly interviewed against his will by Scott Tibbs for his documentary in his obsession to find out more about Jigsaw's motives following his best friend Adam Stanheight's disappearance. To do so, Scott futilely tried about being Daniel's cousin and, after refusing to sign the papers to prove it, tried to sneak into Daniel's room, but a nurse and a security guard came across him and demanded him to leave so he would not disturb Daniel and other patients, which Scott reluctantly did. (The Scott Tibbs Documentary).
Answer: It's never explained in any of the movies, so any answer would be pure speculation. Likely, he was sent back to his mother since his father vanished. And I'm assuming he'd have some sort of trauma/PTSD and would likely need therapy.
Question: Why would there be a tunnel system with an industrial bathroom beneath a house in a neighborhood? I know John Kramer was involved in real estate with his wife and lawyer before he became Jigsaw, so it would make sense that he probably designed it, I'm just not sure what purpose it would serve.
Answer: It serves as the perfect location for John to set up and play his "games."
But it was mentioned in Saw IV that John was involved in real estate development prior to becoming Jigsaw. So if those tunnels already existed underneath those houses, what purpose would they serve?
Answer: The events of Eric going through the house take place many hours after the house trap. It's shown that Daniel has been rescued by Amanda and Jigsaw. There was also a point in the film where its explained the safe contains an antidote. So Jigsaw/Amanda opened the safe to use the antidote on Daniel while removing him from the house. So the syringe on the floor is used.
