When Jack met up with his grandad at the retirement home or watever it was he kept trying to escape from (when he got Christian's shoes) he told Jack something along the lines of "one of these days I'm gonna get out of here and go somewhere no one will ever be able to find me." When I first saw it I thought for sure that meant his grandad had been to the island or at least knew about it and I thought it would have relevance to Jack's connection with the island but since then there hasn't been any mention of him. Any thoughts?
P.S. this is my first post...please be gentle :)
