When the Autobots get blamed for what happened to Impactor, things are not gonna look good in his favor. Meanwhile, Ratchet finds Impactor and wants to save him.
Then, the Autobots discuss a plan to take the Allspark off-world, but if they do that, Cybertron's done for. Starscream is aware of Megatron's plan to reformat the Autobots into Decepticons and votes against it. Looks like we got some dissent among the ranks. Then, Shockwave wants information from Ultra Magnus even if it means torturing him. Brutal.
As Mirage, incognito as a "Decepticon", tries to stay hidden, but fails, Chromia comes to save him. Then, the Autobots come to Ratchet for help. But, he can never forgive Prime for prolonging the war. And, look! Impactor's here! But, why attack Mirage when Prime's here to help?
Then, as Jetfire and Skywarp find out about Autobot Command, backstab alert! Jetfire betrays the 'Cons and flies off.
Now, Megatron's plan will begin... as planned.
