I thought Linebeck was a very extraodanary character. He was very funny, I thought he was a bit like Jack Sparrow. He was a big coward most of the time, which gave him a lot of his humour. "I'll be cleaning the rudder." "I was in the crate. It was boring!"
And at the end, he sacrificed his mind to Bellum to save Link. So he kind of became a hero. He also didn't wish for treasure, instead he wished for his ship back.
I'm not laughing. It moved me too.

Back to talking about the end of game, it could not possibly be a dream. When Link and Tetra went on the ghost ship, it brought them to the World of the Ocean King. Oshus and Ceilia must of given Link the phantom hourglass as a way to remember them.
