|Sonic's friends—and enemies—have all returned home to their own world, but Sonic himself has been conspicuously absent for a week. With his nemesis gone, Dr. Eggman engages in increasingly ridiculous, but harmless, displays of power, hoping to draw him out. Amy, meanwhile, has considered Cream and Vanilla's proposal that she might live with them. Just as she is about to explain why she will not agree to it, Eggman arrives, blaring his plans for world domination over the entire suburb. When Amy attacks with her hammer, he only rubs in the fact that Sonic has not returned to her. As Amy unleashes her fury on Eggman, Knuckles and Rouge also sit together, each missing Sonic and razzing the other about it until it escalates into a full-scale battle. Drawn out by the noise, Tails flies the Tornado to the scene. He attacks Eggman with massive firepower, aided by a transformation mode that Chuck had installed in secret. Eggman responds with an incredibly persistent tracking missile that Tails cannot shake off. His display finished, Eggman orders Decoe and Bocoe to press the self-destruct button on the missile before it hits Tails, and when they confess that there is not one, he becomes distraught. It seems to be all over for Tails, until a flash of light from the moon comes closer and turns out to be Super Sonic. Sonic blows up the battleship, but rather than being frustrated, Eggman is happy that their old game is on again. Knuckles and Rouge see Sonic flying overhead, and their fight also turns from angry to playful. When Amy sees him, she runs after him until he lands at her house. In tears, she confesses that she had just made the decision to wait for him forever, and begs him to tell her that he loves her. In response, Sonic hands her a rose and gives her an inaudible answer and she embraces him. (The English dub changes this scene significantly: Amy demands that he never leave her again, to which he audibly replies that he never will.) Six years later in his own world, Chris is a skilled scientist himself. He is just putting the finishing touches on the dimensional transporter, in an attempt to cross to Sonic's world. Reminiscing with his classmates, he recalls the last night Sonic spent in his world. Sonic had the seven Chaos Emeralds with him throughout their trip to the villa, and therefore could go home whenever he wanted to... But he took Chris on one last run around the lake before using Chaos Control to go home.|

When Molly, Shadow, and Rouge set out for a nearby mineral mine to get the Chaos Emerald, Leon, another member of the resistance, asks Molly to bring back a disc from the mine. They find the Emerald, but the locker allegedly containing the disc is booby-trapped. As soon as they escape, the Metarex arrive; they have told Leon that they will spare his planet if he hands over Eggman.

In response, Shadow removes his limiters and completely annihilates Pale Bay Leaf's fleet (though Pale Bay Leaf himself survives).

The episode starts off with Vanilla stopping by the Chaotix Detective Office to thank the Chaotix for all that they did for her and Cream. Amy and Cream then bring a whole bunch of snacks to Tails to try to cheer him up. (Note: This entire first part, almost four minutes long, was cut in the English dub of the episode.)Chris and Knuckles have a little discussion about what is next for Chris, and they fall along the lines of where Chris' home would be now that he cannot go back. Rouge is seen in Eggman's ship staring at Shadow's pod. After a run-in with Eggman, Rouge suspects that he's hiding something about Shadow. Chris then flashes back to the point just when the planet with Cosmo on it was being destroyed. Lucas is seen following Hertia to peace. Suddenly, the planet begins to expend all of its energy. Punching Sonic out of the way, Shadow uses the last of his energy to perform Chaos Control to stop time, giving everyone else a chance to escape. Eggman then worries that Shadow may not have survived the Chaos Control he did to save everyone, and he begins to feel some remorse for Shadow. Meanwhile, Sonic approaches Tails with only a seed from Cosmo. Tails, already upset about losing her, finally falls into Sonic's arms, punching him and crying to him that he could bring her back and that he believed in him as they fly away. Near the end of the episode, Bokkun gives Chris a letter, which surprisingly was not rigged. When Chris arrives at the location he was supposed to go to, Eggman shows Chris an egg-shaped pod that will take him home, but there's a catch: Chris only has three minutes to return home, or else he could be stuck in Sonic's world forever. Chris has no time to say goodbye to his friends, just as Eggman planned. Chris then leaves Sonic's universe via Eggman's pod. Once Chris is gone from sight, Eggman says that with Chris out of the way, he can continue in his creation of the Eggman Empire. The Sonic's gang proceeds to seek revenge, while Shadow is seen placing a flower near a grave, presumably Molly's grave (This is cut in the English dub). After the gang sets off, a pot with the seed (apparently the one Sonic found) is shown, meaning that resurrection of Cosmo could be possible. The episode and the series ends as the pod with Chris in it flies out into space and then twinkles out.
