Don't want to say good or bad yet, but definetely sketch. Also dead I think. Way to go Locke.. will someone take him out already?
Speaking of that, how come he can kill Naomi but not Ben, his dad, or Jack?
yeah probably dead- that knife went right through her back...but jack did make contact with someone from her crew...
and speaking of Locke- what happened to his brief paralysis? I thought it might have had something to do with Jacob but obviously he got his feeling back in his legs...
I still have (slightly waivering) faith in Locke. He's demonstrated that he's not much of a killer, so if he killed Naomi he had what he at least thought was a really good reason for doing so. The difference, I think, that killing his father would be personal vengence and he couldn't do it. He's a philosophical guy and I think he could justify killing Naomi for a philosophically "just" reason.
I think he's privy to some information from Jacob or elsewhere about the potential damage Naomi could cause. I have a feeling she's from the group wanting to harness the power of the island and Locke is trying to keep it from being exploited. Locke's also long been adamant about staying on the island so his motivations are a bit suspect, but of course nothing would prevent him from staying if rescue came so there must be more of a reason for him not wanting anyone else to leave, either.
Also what are the chances we've seen other flash forwards without knowing it? Some of the back story from season 1 - 3 was clearly back story, but some of it isn't time-specific.
