The brunette-haired woman and the sentries looked over the side of the ship and notices an unconscious Abigail sinking deeper into the water. "Can you save her?", she asked them in curiosity. "I can't swim", he simply answered as his comrade shakes his head. Neither does he? So be it. Not surprised, the female gave a groan of frustration. "Prides of the King's Navy, you are. Do not lose these", she first scoffed before handing them her pistol, and sword belt. Climbing onto the railing, she dove into the water. 

As Abigail drifts down, still unconscious, her round necklace slipped loose from her bodice. Except it wasn't just a necklace. As it turns slowly, a skull was visible. A shaft of filtered sunlight hits it, and it glints. Trying to register what's going on, the sentries looked at each other, before a gust of wind comes up, and they looked at the British flag, holding their hats. Nearby, Norrington rushes down to the pier, being followed by his men. 

Abigail's unmoving form hits the bottom of the shallow ocean. The brunette-haired woman swam down to her as fast as she could, and eventually wrapped an arm around her. The girl's weight was light, which helped her rescuer get a better advantage. Making for the surface, she struggled, making slow progress. The dress this girl was wearing was too heavy, and the water was weighing them down. Forced to be submerged, she forced it open, and skinned Abigail out of it, kicking it away, leaving her in her elbow-sleeved underdress.
 
As she surfaced, the brunette was exhausted, as the sentries helped her haul Abigail out of the water. Laying the girl carefully on her back, the sentries tried to check if she was breathing. "She's not breathing!", one of them called out. "Move!", pushing them aside, the brunette slips one her knives from its sheath. Kneeling over the unconscious girl, she slit the corset down the middle with it, and forcefully yanked it open to allow Abigail to gain air for her crushed lungs.
