It's nice, this - just taking turns around the spring, private and tucked away from everyone else, listening to Finnick tell him about things he's never seen and maybe never will see. Do dolphins and sharks exist in the sea that supposedly exists outside their (apparent) island? Perhaps those are just creatures from the place that Finnick called home.

Levi feels his shoulders unwind and relax a little more, sinking a little closer to him. His feet mostly don't touch the bottom of the pool, so he's just relying on Finnick here. That's nice, too.

He's trying to recall what the dolphins and...whale-things looked like. At some point along the way he'd picked up basic knowledge of animal classification, like mammals and fish and birds and insects, but his knowledge of science beyond that is rather limited, aside from a few random facts lodged into his head during one of Hange's ramblings. When Finnick starts talking about 'frontal cortexes', it's like he'd suddenly started talking in another language.

Levi blinks at him a bit, digesting all of the information. "Dunno what a...cortex is. But you're saying they're intelligent enough to understand feelings, is that it?"

Don't all animals have feelings?

And of course:

"Is it really called a blowhole?"
