Synopsis
After Kari collapses in the heat from sickness, Tai searches desperately for medicine to help her. Kabuterimon flies them to a nearby city, and Izzy uses his laptop to locate a pharmacy where they could find medicine. This proves a drastic mistake, however, as Machinedramon is given their location every time they plug the laptop in. Machinedramon sends Digimon out to all the locations in which the pharmacies were found. Meanwhile, after finding a pharmacy, Izzy plugs in his computer yet again to find the best specific medicine for Kari, still unknowingly, giving Machinedramon his exact location. They find the medicine, then they are ambushed. Izzy and Tai manage to escape, but Tai loses control in impatience and screams at Izzy. He feels responsible for his sister, and he reminisces of another time his sister was sick. Tai was much younger, as was Kari. All he wanted to do was play soccer, despite being told to watch his sister at home because she was ill. Overcome by selfish desire, but not wanting to leave his little sister alone, he brings her along to the park where he attempts to play kick back with her. He begins to get frustrated that she can't kick it well, and tries to teach her. Not long after, she collapses, and an ambulance comes. Tai is harshly scolded by his parents because she nearly died of pneumonia. When Kari comes home, she says she apologizes to Tai for not being able to kick the ball right, helping Tai to make his point of, "she only cares about everyone else." After Tai calms down, they at last figure out they were being tracked by the computer systems. Izzy quickly adjusts the program so they cannot find them. Soon after Tai and Izzy meeting back up with Sora, T.K., Kari, and, unfortunately, Machinedramon. The episode ends with Machinedramon attacking the group, specifically with the kids falling into a deep black hole, the innards of the destroyed building.

Dubbing changes

 * The English dub cuts out a moment when Tai is slapped by his mother (in the past), though there are still obvious signs of it taking place, such as Tai's red cheek, and his mother's raised hand.

Real-world references

 * There's an advert for Nimolta on one of the buildings. It's an anagram for Minolta, a camera manufacturer.
 * When they reach the city, T.K. exclaims "Is that America?!"
 * Tai also says "It looks like one of those theme parks in Florida". He may be referring to Epcot.

Miscellaneous trivia

 * This is the last appearance, in the series, of both Greymon and MetalGreymon.
 * Mekanorimon is one of three Digimon in the analyzed twice in the series, the other ones being Andromon and Kuwagamon.
