He really didn't know what the deal with those bubbles were, honestly. They made him think of Nino, though, so there tended to be a small flurry of small very bright bubbles that were blue and red, mostly blue with just a bit of red on top.

But he tried to focus on the words said, not the flurry of bubbles that made him miss his friend. "Okay," he said. Why... was he bothering to tell him this? He didn't understand. Was he going to be told what to study while he was gone? Well, maybe that was a chance to slip away for some freedom... maybe? Or was it a trap and he was waiting for him to do that?

So a mix of confusion and wariness, but neither very strong at the moment.
