Destruction of the Interceptor

The destruction of the Interceptor

Near t he end, Barbossa's daughter and Elizabeth's adoptive sister, Ruth briefly dueled her biological father before Jack revealed their true parentage between each other. Barbossa released Elizabeth and Jane and Jack as he kept Mia Sparrow, Will Turner, and Ruth Swann captured.

Prelude
After the attack on Port Royal, Barbossa had within his grasp Elizabeth Swann, the daughter of Weatherby Swann and Jane Turner, daughter of Bootstrap Bill Turner. However, he mixed both of them up with thinking Elizabeth Was Bootstrap's daughter, not Jane. Afterwards, Elizabeth's sister and Jane's brother, Ruth Swann and Will Turner allied themselves with Jack Sparrow in order to save Elizabeth and Jane. Mia joined the crew shortly after failing to find a crew of her own once learning that both Jane and Elizabeth were captured and just wanted to help her brother reclaim the Black Pearl from Hector Barbossa. Anamaria was convinced that the pirates wanted Elizabeth and Jane. However, Jane points out that they are not after Elizabeth, but after the medallion. Ruth and Will both went to retrieve the medallion, but are able to get out before the ship sinks completely.

Aftermath
After the crew was captured by the crew of the Interceptor, only Ruth and Will were the only ones able to escape capture. Elizabeth watched as the ship that had entrapped her sister and the man she loved, she nearly attacked Barbossa, only for him to throw her to the pirates. During this conflict, Will told Barbossa to release Elizabeth and his younger sister, Jane and the crew remained unharmed, to which the pirate agreed to. However, before something happened, a sodden Ruth Swann appeared from the deck and challenged Barbossa to a duel. Father and daughter dueled with each other, unaware of their true heritage between each other and Barbossa gets the upper hand and almost kills her. To save Ruth, Jack mentions that Ruth is his long lost daughter.
