Day 2: 12:00 Midnight-1:00 A.M. - S2-E17
Corrected entry: In the second season's 12.00-1.00 a.m. episode, right at the start of the show, we see Kim Bauer being held by the neck from behind by the gun-totting Garcia in the liquor store as the police were closing in. The next scene we see her on the floor holding a piece of cloth against the storeowner's belly wound.
Correction: The scene which Garcia holds a gun to Kim's neck is displayed as part of the "Previously on 24" montage. The first scene of the actual episode is where Kim has been presumably released by Garcia to help the storeowner.
