Blood Must Have Blood: Part 2 - S2-E16
Continuity mistake: In the scene when Octavia and Maya enter the mess hall while trying to escape the guards chasing them, you can see Maya is walking in front of Octavia. In the shot immediately after, though, Octavia is the one in front and she is being stopped by a guard pointing a gun at her. In the following shot we are back to Maya walking in front still trying to cross the hall, just as she sees guards appear from around the corner; that is the point when the two turn around, and we are once again presented with the same shot of the guard intercepting Octavia, only from a different angle.
