At the end of Pirates of the Caribbean: At World's End, Will Turner gets bound to the ship and Elizabeth waits for his return every 10 years. My question is twofold:
Firstly, we see throughout the movie that it's possible to live for short amounts of time aboard the Flying Dutchman. Why can't Elizabeth come aboard for a visit here and there?
Secondly, we also see that Davy Jones was able to come ashore with a bucket of seawater, why can't Will do the same?
