Day 3: 4:00 A.M.-5:00 A.M. - S3-E16
Continuity mistake: When Michelle shoots the escaping hotel customer, her gun shows a jammed shell casing while she points her gun at him. The jammed casing wasn't there after she fired her final warning shots and disapears suddenly just before she shoots him down. (00:39:00)
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.
