On the morning news The President reports about the merging planets and spending the last day with Sonic and the others until they go home. Outside Chris meets Sonic at the swimming pool who asks if he would like to go for a run with him. Tails and Chuck are working on a machine to initiate Chaos Control to send Sonic and the rest back. At school Chris and the others know what's happening until an army of flying robots start invading Station Square. An army colonel has, against the president's will, sent the robots after Dr. Eggman. Dr. Eggman is now under attack, when Sonic arrived and attempted to save Eggman. Eggman handles the robots himself with his flying fortress, and gives Sonic a box containing the last part for the Chaos Control machine. Meanwhile Rouge, Knuckles and Topaz went to rescue the President from an army of agents. Sonic went back to the lab and gives the last piece of the machine to Tails and Chuck. That evening, Chris got ready to say goodbye but he feels sad. Everyone had left the mansion and had gone to the portal. Tails and Chuck start up the portal but it stopped working. Sonic gives them the Emerald he found and they start it back up. Eggman, Decoe, Bocoe, and Bokkun in the fortress, along with all the other creatures that came through from Sonic's world, go through the portal, but it stopped working again. Tails didn't want to give up and Chuck says that they have to adjust a few things. Just then, Sam arrives and before he gets out of his racing car he drives away quickly, wondering if he could step down since he no longer has any real challengers. Everyone had a little laugh but Chris didn't. Tails works on the portal and manages to get energy from Space Colony ARK and starts it back up. Everybody said goodbye as Chris feels worried. Meanwhile Scarlet and Mr. Stewert looked at the energy and Scarlet wonders what Mr. Stewert is and Mr. Stewert says that she will have to keep investigating. Chuck tells everyone that they can't keep the gate open long and demands them to leave before a power failure occurs. Amy, Cream, Cheese, Vanilla, Tails, Rouge, and Knuckles leave now, and as Sonic is about to leave, Chris says goodbye to him(But his mind doesn't think so). Just as Sonic is about to step through the portal, Chris runs over and shuts it down.
