The Internet Anagram Server ("I, Rearrangement Servant") says that "John Locke Smokey" really is:

Shlock Omen Jokey

It all fits.

Whom did the blond headed kid (Jacob? Aaron?) mean when he said, "you can't kill him." to NotLocke?

Hmmm...the 1st time around I thought he meant Jacob. But now I don't. Did he mean Sawyer?

And what's up with Sawyer being able to see him but not Richard?

Because Sawyer is a "candidate"?
<shrug>

He was behind Richard, he could have run away before Richard turned around.

You mean, ignore what actually happened on the show and make things up? Ask endless questions about things they have already made clear?

IMO, running around in circles for no reason other than to show that we're "thinking outside the box" clutters the conversation to the point where the real questions up for debate are lost in the noise.

Such as?

I lean towards thinking Flocke and MiB are the same person(after all, Jacob did say "looks like you found that loophole") but I do have some doubts.

IIRC the lost producers have confirmed that it is smokey/MiB that is now in Locke's form. I'll try and dig it up after work today.

Such as? The quote you just provided is proof enough.

There's always the possibility of a differing perspective on what is, and is not, clear.

Not to mention the fact that rampent speculation is sometimes fun.

Looking at the list of names on Lostpedia (not sure if all of the lighthouse names have made it up there yet...actually I know they haven't because Wallace at 108 isn't listed_ a couple observations:

1. Miles is alive, but his name is crossed out. Last we saw Rose, she was alive and her name is crossed out, though we don't know what happened to her and Bernard after the bomb/flash. Claire's name is also crossed out, questionable whether she should be counted as "alive"

2. Kate is the only name that isn't crossed out that has a number that isn't one of The Numbers.

I'm racking my brain, I forget how Jack learned that Claire's his sister.
