Never saw that coming

Jack likes football?!?! Totally saw him as a hoops fan. That blew my mind.
Also blowing my mind -- almost every single moment of last night's ep.:
Claire was also the lead singer to Evanesence!
Locke, who we have long thought may be a moron, might actually be something more sinister! (consider - the C4 in his backpack, throwing Patchy through the death wall, his evasiveness when asked about these things). Is it conceivable Locke is now an Other, or at least doing their bidding? At some point did he read/see something in one of the hatches telling him what to do?
Claire and Jack better not make out because that'd be extra gross since they're half siblings!
More fascinating insight from Patchy - Kate could never understand what's going on with the Others since she's not on the List - the List seemingly of people of a certain enlightened mental mindstate. Presumably this List is part of the Lists that Ethan and Goodwin were supposed to make after infiltrating the newly-crashed Losties. And there was reference a few eps back to Jack NOT being on Jacob's List - whoever Jacob is. Who is on the List? What's the significance of the List - are these people to be recruited?
We had another scene of seeming self sacrifice by the Others, perhaps aimed at keeping information from the Losties, when Patchy thanked Locke for throwing him through the security perimeter. That, the Claire/Jack connection and the List idea go toward my new grand unifying theory of the island: the Others, who predate the Dharma Initiative by many many years on the island, were/are some kind of super secret society that protects/serves the island (the black smoke monster being some kind of manifestation of the island's consciousness?). They are trying to create higher level people with the island's help - sort of a variation on the story of Prometheus. Through the island's time-bending abilities, it deliberately manipulated to get certain people on the plane as it knew the jet was going to crash. The connections between the Losties, such as the Claire/Jack thing, tell me that while the plane was not deliberately brought down, some of the people were fated to be on the flight.
Finally, that look of betrayal on Kate's face when she saw Jack and Tom throwing the pigskin around all Kennedy like was perfect. There's gonna be some asskicking.
