Maybe she's just there because of her husband, Javier Bardem.
 * Of course that's the theory of the story...and should be taken as such.
 * Then again, there are some (myself included, obviously) who wants to see the daughter of Blackbeard return in some capacity. Same can be said about other character whose stories have reached its needed end (*coughs* Will)...but Angelica's case is totally different - her final scene was a straight-out cliffhanger, not a conclusion to a love story that could've ended right there.

Ending rant. Of course either situation is a non-story as neither characters are confirmed for P5 as of yet. It's just a fan's hope based on recent news, I suppose.
