Looking back at past episodes

So I know there's a portal on this site for info from past episodes, but since we have some down time until season 6 I thought we could do a little dissection of clues that may have popped up.

I'm in the middle of watching pilot, part 1 and a few things came up I need to address. First off, Vincent always seems like he's lingering in the shadows, watching whats going on. Is it possible that mm, or someone, is viewing what unfolds through Vincent?
Secondly, I just had a thought about Locke and his ability to walk on the island. Is it possible that the reason Locke can walk once he is on the island is because MM has already taken over his body? Let me know what you think!

never thought of that. maybe this explains why some people have black eyes sometimes.
like when jacks eye changes when he asks kate if she can take dan to the others camp.
also claires mom has one black eye when jack asks her what she is doing in Los Angles.
it is really a partial possession by mystery guy.
good theory.

amazing.... good explanation for something i had noticed too! i think you nailed it.

I've been contemplating this since the finale.I've been wondering at what point has MM being possesing people.The point you make is the most probable point in time that MM took over Locke's body.The question is where does he get this ability to possess Locke's body while Locke's body is in the crate? Are we actually seeing Locke's spirit? I doubt it.But cannot rule it out.What do you think?

Wow! They really had "black eyes"??? I never noticed that!! Are you sure we're not just looking too much into this? I will have to go back and watch some of these episodes because I've never noticed anything different about their eyes. I agree that just like Ricardus is a much bigger part of this whole thing than he lets on so is Vincent. Who or what he is-not sure but there is something about him just popping up anywhere. Maybe he's Jacob too.
