As reported in the thread Time travel, we're told in the "Assassin" timeline that Bartolomeu arrested Nathaniel Hawk, who had been causing trouble near Concepcion. This makes no sense for all sorts of reasons. One is that Hawk's own storyline is set almost a century later. Another is that one of the side quests of that has Hawk assisting Bartolomeu. And the political situation in Hawk's storyline has Britain, Holland and Portugal allied against France and Spain, with Hawk (at least initially) aligned with Britain. I suggest altering the text in the "Assassin" story so that Bartolomeu has arrested someone else. Possibly Captain Hook, if we want another playable character to be the victim. Or some villain not currently named in the game, e.g. Long John Silver. Or just make up a new name.
