Does anyone think that somehow, someway, Penny and Desmond's son Charlie Hume is Charlie Pace? He is Charles Widmore's grandson and Charlie Pace and Desmond had a close bond on the island ending in the Looking Glass station when he told Desmond "Not Penny's boat". Mabey Charlie Hume is soon kidnapped to the island and he ends up back in time with Jack, Kate, Sawyer, etc. and has to leave the island early on a sub to grow up as Charlie Pace, anything is possible on this show, mabey the writers will see this and incorporate this theory or mabey Im right!!!
