Oh, that's right. Gohan forgot that the Empire restricts formal education to the upper classes. That serves as a reminder.

"I did! I had just started at a new school before I came here. I'm going to take classes here, too. Language classes, first."

"Oh, and just talking to me helps, so you're already helping. It's nice to meet you, Donnie." Gohan knows that immersion and practice are the best ways to successfully learn a language, so he's happy to just have conversations with those fluent in the local language.
