Continuity mistake: In the scene in the laundry room Claire thinks back to the bank robbery when she would have gotten blood on her blouse. The recall shot shows her standing in the bank wearing the blouse. In the original shot during the robbery she was laying on the floor wearing a black jacket and would not have gotten blood on the blouse under the jacket. (00:06:00 - 00:20:00)
Suggested correction: Blood could have seeped through her jacket to her blouse.
