Finnick's eyes are instinctually on the fish as it comes up out of the water, and he reaches to grab it and pull it into the boat. But his gaze snaps over as Sky yelps, and he sees her fall into the water.

"Shit!"

Just as instinctually, he steps up onto the side of the boat and dives in, opening his eyes to find her in the water, then grabs her and pulls her swiftly to the surface. He makes sure they're both next to the side of the boat.

"Grab me- grab the boat-" he instructs quickly, as soon as they're up above the surface.
