Lame for Locke to be dumb. I liked Locke smart. Not a bad episode all told.
I was really frustrated with that while I was watching, but when it ended, I decided it wasn't actually out of character. He anthropomorphizes the island, believes it healed him, and when he gets captivated by an idea, he does throw caution and reason to the wind. Look at his complicity in Boone's death, and his obsession with getting into the hatch. And the thing is, just enough happens to feed his island-related beliefs, that you can see why he keeps acting like he does. After all, it was only by following his hunch about the verse on Mr. Eko's stick that they found this new station. It is also not OOC for him to not share information with his fellow castaways.
That said...
I watched. I hate it when people know important stuff, ya know, like that the house is wired to explode or that the computer is more than it seems, and then don't bother to tell anyone. It never ends well.
Yes! A thousand times, yes. I'm having a really hard time understanding Sayid and Kate not sharing the information with Locke, like immediately (!!!) after they found the wiring. Craxy.
I thought this was a good episode -- much better than most of what we've been fed this season. I was as pleased as punch that Sayid figured out Patches was lying to him, and that Kate had some skillz, again. I liked the Sayid flashbacks. I also enjoyed the Sawyer B plot.
I was frustrated that Sun wasn't showing yet, until I remembered that the show doesn't operate in anything close to real time.
