Trust.The Autobots, being learned from their recent bitter experience, are not very friendly disposed towards Scavenger. Smokeskreen considers him a traitor and even doesn't disguise his feelings. So do the kids too, especially Carlos. The Decepticons, in their turn, hope that Scavenger will spy on the Autobots. Scavenger is training Hot Shot when the alarm sounds for a new Mini-con which is located somewhere in the snow-covered mountains. All the 'Bots arrive there and see the Decepticons waiting for them. A battle ensues. Megatron and Optimus Prime start a hand-to-hand fight. While battling they are nearing the brink of a precipice. The Autobots call Scavenger for help, but he disappears, and nobody knows where he is. Smokescreen swears he's abandoned them, but Hot Shot refuses to believe in this because Scavenger is his teacher. The children watch the battle on the monitor in the Autobot headquarters. Suddenly they notice Scavenger on the opposite side of the gulf. Carlos expresses his misgivings that this position is the best for a treacherous blow. Meanwhile both Megatron and Optimus Prime fall in the precipice. Then Scavenger shows up to save Optimus Prime, whereas Megatron falls at the bottom of the gulf. He is alive but heavily damaged. Red Alert tells to the kids that Optimus and Scavenger are old friends and that Scavenger is the most reliable of the Autobots. Smokescreen begs Scavenger's pardon for thinking badly about him. Sideways drags Megatron out of the gulf. The Lord of the Decepticons vows to return and to take revenge on Optimus Prime.
