Lost 6×04 — “The Substitute”: This was my favorite episode of the season thus far. I really enjoy the off-island stuff a lot more than the incessant power struggles on the island, so it was great seeing Locke interact with so many familiar faces in that alternate reality.
I spent about an hour reading different theories about what might be at the root of all this island/off-island stuff, and the one I like the most so far is that all of the island stuff is just a figment of John Locke’s imagination. He is imagining himself as an able-bodied bad-ass and populating his magical island with people he has run into in real life. Sure, that doesn’t explain everything and is probably pretty unsatisfying to most people, but how can anything else possibly make sense? Smoke monsters? Reincarnation? Time travel? There’s no way to reconcile the supernatural events logically. The happenings must be the result of someone’s imagination!
The names on the cave ceiling weren’t that big a deal. We already knew there was a list and we knew that the numbers were significant to Jacob in some way. I’m not sure why that ceiling was reserved for the end-of-ep reveal. I guess it was more dramatic than having the info scrawled on a scrap of paper — but just barely! Oh, well… let’s see what happens next week.
