Kobra's basically never seen this much water in his life and he's already on edge just from that. This is the furthest out he's managed, but he turns his head with false confidence to throw her a cocky smile. Heh.

"I'm working on it." He clears his throat. "Also on the swimming thing. You think they'd let people drown here?"

And then he turns around to face her because it's totally rude not to and he's not really too concerned with his lack of clothing right now.
