My Sister's Keeper

When Kari becomes dangerously ill, Tai sets out to find some medicine in the adjacent city, and Izzy's laptop manages to attract some unwanted attention.

Synopsis
After Kari collapses in the heat from sickness, Tai searches desperately for medicine to help her. flies them to a nearby city, and Izzy uses his laptop to locate a pharmacy where they can find medicine. This proves a drastic mistake, however, as is given their location every time they plug the laptop in. Machinedramon sends his Digimon minions 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, only to be ambushed by Machinedramon's army. Izzy and Tai manage to escape, but Tai loses control in impatience and snaps 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 wants to kick a soccer ball around 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 mother because Kari nearly died of. When Kari comes home, 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, but this only causes Machinedramon to order "Operation Elimin-8": having Megadramon and Gigadramon destroy the whole city to flush out the DigiDestined.

Fearing the worst, Tai and Izzy meet back up with Sora, T.K., and Kari, who escaped the building they hid in before Megadramon could destroy it. Unfortunately, Machinedramon arrives, forcing the group to hide in a nearby building. Sneering that the chase is part of the fun in a hunt, Machinedramon destroys the building, and the DigiDestined fall into a deep void...

She's one of the DigiDestined! Have you forgotten that?!" Tai: "Not at all, but her being sick...We should have left her some place safe. We should have split up so someone could take care of her while the others looked." Izzy: "Split up?! Tai, this isn't like you!" Tai: "I'm just a little... worried about her.

I mean, I knew she was sick, but all I could think about on the way home was playing soccer." Young Tai: "Hey, I'm home!" Tai: "I wanted to go out and play, but I didn't want to leave her by herself, so I took her outside with me. She seemed okay, really she did." Young Tai: "Now watch me, just like that. No, that's not right...Kari? Kari!" Mrs. Kamiya: "What could you have been thinking!? You knew she was sick!" Tai: ''"She ended up with pneumonia, or something. She almost didn't make it, but what really kills me is what she said when they brought her home from the hospital. The first words out of her mouth..." Young Kari: "Tai, I'm sorry I can't kick the ball very good. You'll probably never want to play with me again." ''

Tai: "That's her, that's Kari. She never thinks about herself. It doesn't matter if she feels bad or if she's bummed out about other stuff, she's always worried about the other kids. She wouldn't be sick, she would be just fine if she never came to this stupid place, but she came because she knew that we needed her help. You never thought about what she wanted. She never does!" Izzy: "Because she cares." Tai: "She's a kid! I'm her big brother, I'm supposed to look after her and protect her and think of what's best for her! That's what I'm supposed to do!" Agumon: "Oh Tai..."
