Season 1, Episode 10

summary written by Rachel

The episode starts with Izzy and Mimi, both on their beds with their digimon, crashing into two different islands. When Mimi wakes up, she's in a forest. They decide to wander around. Izzy and Tentomon are in some kind of ancient ruins. Izzy decides to go in there.
Mimi finds some bananas and Palmon uses Poison Ivy to reach them for her. Mimi peels her banana and there isn't anything there. Palmon doesn't peel it, instead she eats it whole. Mimi throws her banana away. Some pink sludge falls a few feet away. She realizes it's sludge and not hair mousse and quickly moves away. Palmon introduces Sukamon and Chuumon via the Digimon Analyzer. Mimi and Palmon quickly run away while Sukamon and Chuumon go after them, throwing sludge. Mimi stops running and insults them. When she does, they follow her. She stops at a tree and starts whining. Sukamon and Chuumon slide down the tree she hugging and touches the digivice that Mimi has clipped on her bag. A light emerges and Skamon and Chuumon start glowing. Palmon asks them if they had seen any humans around there and they said that they did see one fall onto the parallel island. Palmon uses Poison Ivy to get across.
Meanwhile Izzy and Tentomon are inside the building. They see one of Devimon's black gears. He sees the wall imprinted with the same writing he saw inside the battery cell at Andromon's factory. He sees an outlet and plugs his laptop in. He starts typing. Mimi and Palmon burst in as Izzy types. Izzy barely looks up from his computer to greet her. Then he resumes his word. He starts being so boring that everybody falls down.
A lot later Mimi starts being sarcastic. She apparently isn't in a good mood. Izzy gets an idea just as Mimi stands up. His computer screen turns into a map of the ruins they're in. He tells them that they're in a huge maze as Mimi gets out of that chamber and goes out the wrong way. Tentomon follows her.
Izzy and Palmon get out into the sunshine as they realize that Mimi took a wrong turn. He tells Palmon that Mimi could be lost in there forever. He goes back in the chamber and starts typing.
Inside the labyrinth, Mimi and Tentomon are arguing about which way to turn. Mimi trips on a root and falls. Mim tells Tentomon that she doesn't have to follow him and it's his partner Izzy that got her into this mess in the first place.
In the main chamber, Izzy is typing. Palmon sees a little red dot in the north-western corner. They can hear Mimi and Tentomon arguing. Izzy grabs an operator earpiece and the scene switches to Mimi. She can hear Izzy's voice talking to her. Izzy gives her some directions. One of the routes involves balacing on a narrow ledge in order to go around a big hole. A bigger yellow dot is following her.
In the maze Mimi and Tentomon are waiting for directions when they hear a noise from behind them. A centaur-like digimon leaps across the hole. Tentomon introduces him as Centaurumon. They see a black gear embedded in Centaurumon's back. Izzy gives them directions. Mimi runs into a dead end. Centaurumon corners them. In the main room, Izzy has left his earpiece and laptop in there and is not in sight. Palmon isn't there either.
Centaurumon uses Solar Ray and Mimi and Tentomon duck. It causes a hole in the wall. Mimi and Tentomon get to one side and he storms in. Mimi pressures Tentomon to digivolve and he says that he can't unless Izzy is there. The ground starts to shake and Mimi scolds Centaurumon. Centaurumon isn't causing the rumble.
A small patch of light breaks out from one side and it gets bigger until it reveals Izzy and Palmon digging through the wall. They start towards the door and Palmon digivolves to Togemon when Centaurumon produces a Solar Ray. Tentomon digivolves to Kabuterimon and they almost squash the digidestined.
Centaurumon lets go of the blast and they fly out into the open air. He shoots at them again and Togemon and Kabuterimon combine their attacks, Needle Spray and Electro Shocker and fire them at him. The black gear flies out and dissolves.
He wakes up and Mimi asks him questions. He looks at Mimi's digivice and and takes them to a room. He shows them a carving on the wall that matches the outline of the digivice. He tells them that it is called a digivice and that it is the last line of defense against the darkness that threatens existence.
Leomon steps in behind them. He says he must destroy the children. Leomon aims a punch at them and Centaurumon hold out his hand. Their hads interlock and Izzy says that time is standing still. Centaurumon says that he must protect the children because he is the guardian of the temple to the digivice. Leomon uses Fist of the Beast King. Centaurumon dodges it and he uses Solar Ray. The attack sends Leomon to the wall. Leomom attacks Centaurumon again. This time, Centaurumon is badly injured. Leomon starts toward the children. Mimi holds up her bag to hide her face. Izzy notices that her digivice is reacting and he holds up his. Both of the digivices' light makes Leomon run. When he is out of sight the digivices stop shining.
In the main room, Izzy asks Centaurumon if he can stop the black gear from turning. When he says no, Izzy starts typing again. Mimi gets angry at him and kicks the black gear. It starts turning the other way. They go outside to where the islands almost meet and Sukamon and Chuumon are still there.
