The Ultimate Team No More?

S1 E6: Marcus and Agumon fight and defeat Tortomon, but Yoshino takes them to task for rushing into battle on their own. Marcus and Agumon remain confident in their ability to defeat whatever foe they face, even if they face it alone. Their bond doesn't last long - they soon get into a silly argument and then refuse to work together anymore. Agumon sulks in his Digivice. Marcus gets into a street fight with an old, human rival and his cronies. When Elecmon appears, Marcus goes after it himself. Realizing Marucs is useless without Agumon, Thomas, Gaomon, Yoshino, and Lalamon move in to help. But Marcus stubbornly insists on fighting Elecmon alone, even when it digivolves into Garurumon. Marcus leaps on the Digimon's back, and it runs off. Marcus recklessly fights Garurumon, until he realizes that it's too big a task for one person. Luckily, Agumon shows up to help him, and together, they defeat Garurumon. The Ultimate Team is reunited!
