Teague serves as the Keeper of the Pirate Code, which he keeps with him at Shipwreck Cove. During the Fourth meeting of the Brethren Court in "At World's End", Teague guns down a pirate who attempts to convince the court to ignore the code. He subsequently informs the Court of the conditions required for a declaration of war and the necessary election of a Pirate King. Teague seems to be fond of his son, Jack; when Jack observes that he has survived a great deal, Teague observes that the trick isn't living forever, but being able to live with oneself forever. When Jack asks about his mother, Teague shows him a shrunken head. Jack then comments, "She looks great!".
