wow i really liked it tonight.
Yeah... good stuff. For one of the few times this season, I'm very excited and anxious for next week.
SORT OF SPOILERY STUFF (but not really)
Good batch of easter eggs in this ep, too: the woman whose house Locke was inspecting was Sayid's torture-girlfriend from Iraq, and I'm just about 100% convinced that Locke's dad is the "real" Sawyer, the one who conned Sawyer's parents when he was a kid.
MORE SPOILERY STUFFWE KNOW WHERE THE FOOD COMES FROM!!!! (sort of)

I was disappointed about one thing: I had heard we would see what put Locke in the wheelchair last night. Up until the end of the last flashback when Helen rejects his proposal, I kept saying, "OK, those guys are going to shoot Locke in the spine." "Locke is going to run out into traffic after her car and get hit." "Blue ice from the planes overhead will crush his lower back." But nothing.
It's looking like Locke's dad is the real Sawyer but for that reason, I hope they don't do it. He's the ONLY other con artist we've seen on the show. Besides, how would that information be useful to Sawyer on the island? I would only think it would prove itself important once they get off the island (if that is to happen), when Sawyer can go and find Locke's dad, and that's IF he decides to after shooting the wrong guy in Australia, which we know he has feelings of guilt over. And Locke's dad/real Sawyer is too important to both of their backstories for it to just be another Magnolia moment for the audience like Locke and Nadia's overlap.
But could anyone make sense of what the announcement was saying? I think the lockdown has to do with the food delivery and a friend of mine made the connection that the map might be showing how to get to the food, at least that's part of it. I initially thought that the map was an escape route in case the numbers weren't put in but the blast doors don't come down if the numbers aren't put in so both those conditions would have to be met.
I don't even know.
