As shown in the previous episode, Separatist hover tanks lose hover capability when they are disabled via "poppers" into the two cockpits. The tank that the rebels commandeer should have fallen to the ground before they managed to reactivate it, yet it remained hovering a couple of feet in the air the whole time.
When Ahsoka draws her lightsaber during the attack on the power station, a green glow is emanating from the tip for several seconds before she activates the blade. Lightsabers only emit colored light when the blade is active.
When a dwarf spider droid is shooting at Steela Gerrera who is sniping it from a rooftop, the burn mark from one of its bolts clearly overruns the edge of the building by about an inch.
The narrator states that the Jedi Council continues to observe and advise the rebels. The Jedi Council is not present on Onderon; only Ahsoka Tano, Anakin Skywalker, and Obi-Wan Kenobi are present.
