Pirates of the Carribbean : The Curse of the Black Pearl Mystery ? Read details for explaination.?

Ok, do any of you just think that Pirates of the Caribbean is one of those amazing movies you want to go on, it is so much better than the 2nd and 3rd as it doesn't proceed to carry on, it's an almost seperate story line. There's one thing I've been curious about though, is when at the end Will (Orlando Bloom) is thrown the aztec gold by Jack (Johnny Depp) It isn't Will's blood on the gold, it's Jack's and thats why Jack actually took the coin from the begginging, caus' he knew what he had to do. Also the ledgend goes that they need full blood, not half blood like Will, so something's telling me that Jack is Will's Uncle and Bootstrap Bill's Brother, because they said that Bootstrap was sent with cannon to the ocean caus' he wasn't at all pleased about Jack being marooned on an Island, so something's telling me that bootstrap and Jack were in on the deal with davey jones, Bill already being found, but Jack was next. Just a thought, what do yall' think ?
