''But Will could return to brake the "spell" Blackbeard used to shrink the Black Pearl. Sence Davy Jones could rise the Pearl from the bottom of the sea, why can't Will turn the Pearl to her original size. He is after all still captain of the Dutchman.''
 * Utter twaddle-speak, says I. Will is not in any circumstance to return to the films. Reasons why are clearly put within the films: he can't abandon his duty without turning into a creature like Davy Jones was...and as Will looks nothing fish-like in the AWE epilogue(which takes place long after the four films), he didn't abandon his duty.
 * So unless if for some reason, they found a way to bring Will back(highly unlikely)...any return of Will(or Elizabeth) is a fan's wish, nothing more.
