Well, we don't have to wait until February to see Michael, as he's already appearing in one of those two-minute webisodes that are unspooling at ABC's site, one per week.
In 'The Deal', Juliet visits Michael while he's still being held prisoner by "The Others". So it takes place before his return to the camp as the island's version of "The Manchurian Candidate". And it also adds another layer to Juliet's presence in the show's mythology so that she's not just seen as a Juliet-Come-Lately.
These "Missing Pieces" are fronted by commercial advertising. This is something to remember when the AMPTP claims that there's no financial future in the Internet. I'm not advocating that you should boycott seeing these webisodes - they were produced before the strike was called and I know how hard it is to kick the 'Lost' jones once it's in your blood.
But I just want to make sure everybody knows that Nick Counter and the AMPTP are a pack of lying weasels. And these webisodes prove it!
