A couple of things I noticed:

I was thinking before last night’s episode, Lighthouse, that if it was going to be Jack-centric then it couldn’t be a coincidence that the episode flashes have mirrored Season 1 so far. Well, it was indeed about Jack so that means next week must be a Jin/Sun episode since S01E06 is “House of the Rising Sun.” Interestingly enough, this week Hurley and Jack stumble upon Adam and Eve which they first see in “House of the Rising Sun”, an episode rife with mentions of time, as I mentioned in an old post here. If I’m correct with the episode centric orders, next week will be Jin and Sun and perhaps they will have their reunion and perhaps we’ll find out they are Adam and Eve. Kinda cool if it was set up that way, but I don’t care too much about their characters anymore.

The lighthouse was pretty awesome until Jack smashed it. Of course anything that could provide any answers either blows up or gets destroyed by the writers.

I think my theory about Season 6 could still be in play as it appears “Alternate Timeline” Jack knows something is off as he appears to recognize Kate and Desmond, and he seems to feel that he got his appendix removed recently.

So far I’m loving Season 6.
