The pistol angers the redhead, who glares and swims over to whispers things to the black haired mermaid that's hiding her damaged face. Their eyes narrow at Jack as they keep their distance while the blonde hunts down a fish for their bigger meal. he keeps making man noises at them and it upset the blacked haired one, already angry and in tears over her ruined cheek.
The blonde just stares at Jack, waiting for him to shut up, decide the fish is edible, and trade her something for it. When he does nothing of the sort she hangs on the side of his boat, peering inside. Jack may think he has nothing of value but she'll take a boot, his belt, that pistol, or... ohhh. His hat. She reaches for it, arm just a hair too short. Water from her finger tips drip onto it on the bottom of the boat as the others come closer to see what she's found of interest.
