Aqua came here of his own choice, but he had no idea where 'here' was or what it was going to mean for him. He didn't know that he was agreeing to stay here, almost like he was agreeing to his own kidnapping. Had he had even half an idea of what was happening, he would never have come along with Nagare, curiosity be damned. Then he would've been no different than many of the others. Brought here by force, unconscious.

For now, though, this is actually nice. It's a nice alternative to a situation he didn't even know could've happened.

His smile brightens and his waving grows more enthusiastic and vigorous when some of the others smile and wave back. So far, this seems like a decent place with good people. He'd like to get to know some of them sometime. Maybe ask some of them why they're looking at him with such shocked faces.

Aqua is about to ask about the other building and the many creatures, but all of that is pushed aside when he hears the word 'swim'. He's like a sleeper agent finally hearing his activation word. He practically vibrates with excitement and that nervous energy he was feeling is momentarily gone. Gently, he tugs at Nagare's hand. "Yes please! I would like it see!"
