US Title: "A Dastardly Deed"

The episode starts with the launch of the X Tornado, Sonic and the others are trying their best to find the last emerald before anyone else can. Using the radar, Tails tells Amy that he has no sign of the emeralds. Chris and Danny are also riding along and Chris seems distracted as he looks at Sonic. Elsewhere deep in a forest Eggman is busy enjoying his new emerald and says that he may have a lucky day. Instead of using his cards, Eggman releases a new robot, which happens to be a small gold bell with many charms covering it. Eggman’s aids think that it is the wrong robot but he assures them that since the robot has luck that they will find the last emerald.

Meanwhile Knuckles is using his red emerald to look for the last emerald and he begins to think that he would do anything to get home. He says that unless Sonic and Eggman work together that there is no way that they will be going home. It is then that he hears Lucky, who has fallen onto its back. He helps it up and the robot shows him where Eggman’s base is located.

At school Stuart dismisses the class for lunch and Chris still seems distracted telling his friends that he is not hungry at the moment. Stuart notices him and takes Chris to the counseling office. There Stuart is able to say that he is upset about losing Sonic and the others. Chris agrees without a doubt and Stuart tells him that one day his friends will return home and that it is best to think of what is best for them. Stuart reassures Chris and then leaves the room telling his HQ that everything is ok.

At the white house the President learns of who Sonic and the others came to the planet, saying that if they create their own Chaos Control they could be rid of Eggman. Topaz steps forward and begins to explain that the blast may lead to global destruction, Rouge agrees, and Topaz says that they need to tread lightly. The president says that they need to keep the emeralds apart and wonders how they are going to do that. At his house Chris finds Ella cleaning upstairs and she tells him that Sonic and the others have left to look for the emeralds and his grandfather is out getting parts. Chris notices how empty the place is and flashbacks to everyone enjoying themselves there. As he leaves he runs across Knuckles he explains if he does not call a truce that they will never get home. Chris says that it will never happen and Knuckles continue his idea that they need to join up with Eggman and nothing will stop them from getting home. Knuckles goes to talk to Eggman and Chris decides that he wants to go with him.

At the train station Chris and Knuckles run quickly to the train almost missing it and leaving Lucky behind, who cannot climb the stairs. Out in Forest Hill Knuckles and Chris slowly approach the fort and Knuckles says that he doesn’t mind losing the robot. Eggman’s sensors pick up Chris and Knuckles and as they go to attack, Eggman stops them as he sees them waving a white flag. Inside the ship Knuckles explains his idea to Eggman and oddly Eggman agrees to the idea and thanks Knuckles for the idea. He then goes onto say that he needs to hold onto Knuckles’ emerald saying that they need to trust each other in order to be allies. Knuckles gives him the emerald and shakes Knuckles’ hand. Eggman watches them leave and he says that he has no intention of joining forces with Eggman. Later that night, Lucky is scared by a cat and dumped into a garbage truck.

Back at the lab Cream and Cheese are dancing to the TV while everyone else watches. Chris says that he was over at Danny’s house studying and asks Tails if they found anything and he replies with a no. He sees the three emeralds in the chamber and Sonic decides to go for a run. Chris chases after him and asks Sonic if he gets homesick and Chris says nervously that Stuart says hi. Thinking that everyone is homesick he meets Knuckles at the train station with the four emeralds that Sonic and the others have. In the dump Lucky finds himself looking around oddly. Also, Topaz has moved into the area of Eggman’s ship and says that they will find the emerald; Rouge says she already knows where it is.
