In the previous episode, (Season 1 Episode 18: Everyone Has a Cobblepot) Fish Mooney scooped out her eye, it is then replaced with a different colour to her original, yet in the opening few minutes of this episode (Season 1 Episode 19: Beasts of Prey), she has got 2 brown eyes again.
when the guard shoots Fish in the copter, it then shows the exterior of the copter with no bullet hole in the side even though she was shot.
