Hi all, I'm new here and really enjoying everyone's ideas!
On wikipedia, there is a rumour that in the 3rd film, Davy kills Beckett. Wikipedia didn't say where they got that rumour from, though. It'd be good poetic justice. I've read the draft script, and I hope that the final film keeps to the Davy/Calypso love story. If we follow the story (as it is in the draft, since that's all we've got to go on) the legend of Calypso states that the Brethren of Pirates had her reborn into the body of an ORDINARY mortal woman. Tia Dalma is a voodoo priestess of magical powers who can bring back the dead. An ordinary mortal woman, would, logically have no memories of being Calypso, and Tia Dalma knows the story. Also if Tia Dalma was Calypso, why would there be this big mystery? If Tia Dalma was Calypso, why would Jack steal the locket from her? Also, when Jack gave Elizabeth the compass that she was the only one who could make it point to the location of Davy's heart. They're only theories - Calypso could very well be Tia Dalma. It would work either way, but I think I'd prefer it for drama's sake if it turned out to be Elizabeth. It would be a nice, cheery ending if the spirit of Calypso could be released from (whoever's) body and Davy could be reunited with his lost love and he and his crew released from damnation. Or perhaps he will die for Elizabeth/Tia/whoever he thinks is Calypso. Naomie Harris said Tia Dalma has a dramatic departure from the film. Also, in DMC, when Tia Dalma was telling the story of Davy Jones and his love, she did say that "him never stop loving her."
