Spoiler Level: High
Things progress in logical fashion from last week's episode; Megatron's consciousness takes over Bumblebee's body, he uses it to restore his own body, and then kicks Starscream's butt.
But predictable doesn't necessarily mean boring, as Megatron's return has been a long time coming, and this was a great throw-down between Megatron and Starscream. Plus this episode gave Ratchet a nice chance to be in the spotlight.
As always, this episode is currently available to watch for free at http://www.hubworld.com/transformers/shows/prime/videos.
