There's no need to excuse the questions. When Myca was new to the world above the waves, he wishes someone could have explained things to him. It was even harder to get answers because he doesn't speak. Being unable to give voice to questions left him having to learn much on his own. So, he doesn't mind being able to help someone else. There's a lot of mysteries in the human world, after all!

Ah, Myca brightens a little when he realizes what Aqua's doing. He hands over his food so he can type his replies more quickly. Most times, it's probably another human they're talking to. Normally, he would've said 'person,' but he's trying to mimic the language Aqua uses. Perhaps trying to convey that he also isn't human.
