Digimon Tamers 1x11

A Musyamon attacks Henry and Takato jumps to the rescue. But Guilmon isn't able to win this battle alone, so Henry has to fight with his own thoughts on the subject of Terriermon Digivolving since last time he couldn't handle the power of Gargomon. When a little girl gets into trouble, Henry acts and Terriermon digivolves to Gargomon. This time Gargomon can control himself and destroys Musyamon. Henry comes to realize that there's just some fights you can't avoid.
