It has to be her. Why else would Ben tell Locke to sit down?
His dad's dead. No, it has to be her.
She's the only reason he'd let Ben go.

except they have released pictures of Michael on the boat at abc.

I'm really glad I didn't see that before watching the episode, why would they release spoiler pics??!

Spoile font please

Not unless she had some kind of fancy surgery that turned her into a black man that looks a heck of a lot like Michael. :24:

probably michael, yawn how lame is that

I'm pretty sure that it's clear enough to figure out that Michael is the spy. I figured that out last week. At first I wished it was Ethan somehow cause he was too cool. But it's totally Michael. Why else would he be back?

Locke needs to sit down cause he never expected Mike to come back.

Spoile font please
He posted it about two minutes after the scene with Michael aired, at least here in Toronto.
100%

He told Locke to sit down not because the shock would be that Michael was working for him I assume.

given that we knew harold perrineau was coming back this season, and his name has been on the credits every week, how could anyone be surprised that michael was on that boat?! it would have been a lot more fun if they HAD brought michael back in a more secretive surprising way.

That's exactly what I meant ^^
