Huh? Why would Kaoru want to know if Red-Winged Thunder can swim? Hikaru peers around him to see what the dragon's doing, and--huh.

"I don't know," he admits openly. "He likes fish, so I guess so?" That makes sense, right? Don't most animals only like food that they can catch themselves? Still, though, he doesn't want to have to try to fish it out if it turns out it's a sinker. He releases his brother from the hug in favour of quickly walking to the dragon, hopefully getting to it before it decides to do anything like throw itself into the water. They should probably start moving him onto the ship soon, anyway, before they draw attention from outsiders.
