In one shot, Megatron walks past two Starscreams. One of them is probably supposed to be another character (either Skywarp or Thundercracker), but the colorist painted him with Starscream's colors.
During the battle, Bombshell uses Mirage via his cerebro shell to fire on Thundercracker but it's Skywarp's voice that yells when he's hit.
Cliffjumper in an earlier episode acted rather nice towards Mirage, they even shook hands. Yet in this episode, for no apparent reason, he brands Mirage (wrongly) a traitor at his first suspicious act.
