Continuity: When Rojo attacks the police academy, there is a patrol car right behind her. But when Ben (as XLR8) arrives and slams into her, the car suddenly vanishes.

Plot hole: After Upgrade has successfully removed Rojo's cybernetic parts, the beam rifle she had used in the armoured car heist at the episode's start suddenly appears among them. But when the drone merged with her, she wasn't holding the gun and so it couldn't have been transformed along with her.
