Day 4: 5:00 A.M.-6:00 A.M. - S4-E23
Continuity mistake: In the first scene where we see Tony as a hostage, Mandy comes over to him and he has a white gag in his mouth, which is taut. Mandy says, "Is she gonna do the same for you?" and the camera cuts back to Tony, whose gag is now limp on both sides.
Chosen answer: Nobody knew, not even the writers, until at least halfway through the season when they were writing the end. They wanted to keep all options open.
