Though I can't imagine a single fan out there who will find sympathy for Michael Dawson -- who betrayed our favorite castaways in Season 2 for the sake of his son -- it has been confirmed that the character will return for Season 4.
Harold Perrineau's Michael Dawson Lost Again
I don't know how ABC plans to bring the character back, but JewReview has confirmed that the network is looking to make an announcement of the character's return at this year's Comic-Con.
Will Michael return to the island or will we see him on mainland? Fans of the series will remember the season finale of Season 3 -- best episode ever? -- that ended by showing Jack and Kate arguing near an airport on mainland. It would seem that our castaways had been rescued thanks to the actions of Jack, something the character now regrets.
Will Season 4 kick off on mainland or bring us right back to the island to start all over again? Unfortunately for us, it will be a while before we find out anymore LOST secrets.
Expect more Lost updates with the arrival of Comic-Con this week.
