What if Sing and Tapp did not hide?
As the title says, when Sing and Tapp are in Jigsaws warehouse waiting for him to come up on the elevator. What if they did not hide? Did John have a backup plan you think? Or once he gets to the top and sees them does he just rush the elevator back down?
My guess is I think John knew they were already there and that is why he started coming up at the elevator right when they saw Jeff in chair. I am also guessing John had another way to start the two drills trap other than the wires holding the drills.
