File:Sonic X Episode 78 - So Long Sonic

Description
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.
