When the sun begins to set, the group realizes that they are tired. Matt wants to keep walking because they don't know if it's safe to stop, but Tai says they need food. Tentomon finds a lake for them to camp at. They find an empty trolley car there and decide to stay in it. Now that they have shelter, the group just needs food. The kids and their partners all go to gather things to eat for dinner. Tai starts to realize that Matt doesn't really treat T.K. like a brother. It's much more like he's a bother. Sora agrees with him. As Joe looks in the sky to figure out where they are, he finds that he doesn't recognize any constellations. He can't even find the north star. Tai suggests that they could be in the Southern Hemisphere.

Everyone is getting very tired and are ready to go to sleep, but Izzy thinks that they should take turns standing guard. Tai says that they can all do it for an hour, but Matt says T.K. is too young and needs sleep. He then starts to get in a fight with Tai for bothering Gabumon. Joe finally decides that the order will be Tai, Matt, Izzy, and Joe. Everyone else can go sleep in the trolley. While they're sleeping, Matt has Gabumon go sleep by T.K. to keep him warm.

During his turn, Tai notices that Matt is up too. Matt apologizes and says that it's stressful being in the Digital World and watching T.K. Tai asks if they even live in the same house and Matt explains that their parents are divorced, and he lives with their dad while T.K. is with their mom. After Tai says that that explains a lot, Matt runs away to a nearby island. Then Tai and Agumon hear Matt playing his harmonica. Gabumon hears it too and comes to join his partner.

While Tai and Agumon are sitting by the fire, it begins to spark and the ground shakes. The sparks have hit the tail of a Seadramon, and he's mad. He pulls away the island everyone else is on, leaving just Matt and Gabumon on their separate one. The Digimon try to fight Seadramon, but are not strong enough. Agumon also doesn't have the strength to digivolve. Matt and Gabumon have now jumped in the water to distract Seadramon, but he grabs Matt. As he is in trouble, his Digivice begins to glow and Gabumon digivolves to Garurumon!
