Question: Why does the young red-headed nun, that doesn't sing very loud (can't remember her name), wear a different habit?
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: 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: 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?
Question: In the scene right when they leave the hotel after the wild night, they see Doug's mattress. Is there any significance to the guy that turns to them and says some people just can't handle Vegas?
Question: After Peter yells at Kevin "You spent $967 on room service?!", where does Kevin run off to? It's not clear from what's onscreen.
