Finn shouts and runs after him, pausing only to kick off his boots and--well Poe did say skinny dipping, and that sure looks like he's taking his shorts off, yes it does. Two can play at that game, and Finn races ahead to splash into the water. It's pretty shallow for a while, but eventually it's deep enough for actual swimming instead of wading. The saltwater stings a little on his scar but not badly enough to stop him.

Of course, once Poe's close enough, Finn shoves a wave at him. "Ha. Gotcha."
