Question: Several other answers and corrections state that the reddish liquid sprayed by the tripods was what essentially grew the red vines. However I thought I heard someone in the film say something along the lines of "using us (i.e. blood) as fertiliser". Can someone please clarify?
Question: During point of no return, the phantom has no disguise on. If everyone was after him, why didn't anyone stop the performance and capture the phantom?
Question: Does anyone know if Noah knew all along that the elders were dressing up as the "monsters?" I think he did, and that he thought it was just a game. Is that why he laughed and clapped every time the bell went off and they had to hide? Perhaps the elders didn't hide this from him because he was simple-minded and couldn't talk. So, when he went after Ivy in the woods, he thought it was all for fun. Does anyone else agree with this?
Question: This question applies to the whole series. Why do some of the people who actually manage to survive Jigsaw's traps end up working with him instead of either helping capture him or killing him and insuring that no more innocent people get killed?
Question: Did just New York get contaminated or did the rest of the world get infected?
Question: I don't really understand why Jodie Foster's character didn't tell the police something was wrong when they came to the door. I know she was worried for her daughter but the robbers couldn't overhear and she could have asked the police to come back later, giving her a chance to smash the cameras. Also, considering that she emphatically denied there was anything wrong, why did the police return later with all the guns etc?
Question: Who were all the skeletons that the Mother sees toward the end of the film? It's never explained. Also, what room was that?
Question: Even though Isabel committed suicide, shouldn't she have gone to heaven? She willfully sacrificed herself to insure that Mammon couldn't cross on to earth so in a way, she was saving billions of people, so that should have guaranteed her entry into heaven.
Question: How does he fold the Monet in half to fit into the briefcase? Originally I thought he'd separated it from the wooden frame (ie. just a canvas), but when he takes it out back at his house he holds it up, and the wooden frame's still in one piece. Also, surely folding it in half would crack the paint, but despite the painting being twice the width of the briefcase (it fits snugly when the case is open), he then shuts the case down to a "normal" size. Any ideas?
