Day 3: 7:00 P.M.-8:00 P.M. - S3-E7
Character mistake: At 07:03:05 PM the man pointing the gun at Jack is right-handed, but he aims with his left eye, which is his weak one. He keeps his right eye closed as he walks away and no longer needs to aim, which is a dead giveaway he has never used a gun before.
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.
