Note that the code words were nominated and voted for by fans who had no idea what was going to happen. The only nomination that the producers said was “oddly fitting” was something about a garden gnome or something.
Something I’m wondering: how in the heck would the Others EVER have supported Daniel’s plan? As far as we know, their entire PURPOSE is to protect the Island. They’re not going to let someone nuke it, and they certainly aren’t going to participate: especially not when they have an easier alternative to try: attack the Swan dig before the drill hits “the energy.”
Also, if they followed Daniel’s instructions, it’s currently buried in concrete. How is would ANYONE get to it, let alone get it near enough to the Swan site, in just four hours, even presuming that the Others WOULD help and happen to have a bulldozer around? Because I doubt Jack and Kate could carry the thing on their backs. Unless there’s a lot more about the bomb’s situation we don’t know (like, it’s already on a truck, or you can just blow it up in place and that’s close enough to the Swan to do the trick) why would anyone think that this is an even PLAUSIBLE thing to attempt?
Some more things to think about:
We’re still not sure what Daniel thinks he can change, and what he can’t. We still don’t know what else is in his notebook. For instance, he seemed to know exactly when Chang would be around (he’s right on time). Maybe that’s just from some Dharma schedule, but it sort of seems like he “knew” that Chang would arrive AND that Chang would refuse to listen to him. That implies that he wrote those events down in his notebook. But you’d think, in that case, the producers would then SHOW HIM DOING THAT so that the audience was clued in.
Daniel does act like he thinks he can stop the Incident. Wouldn’t a more plausible way to try that, though, be to appeal directly to the big bosses in Ann Arbor? It would be easy for him to convince people he was from the future if he had enough time, and he had three years. So when did his big “you can change things” epiphany occur? Seems like it happened prior to his sub trip back, because that’s the whole reason he came back. So did he try to appeal to the DeGroots? And how did that play out?
Is the reason that Daniel thinks he can change the Incident because his notebook stops recording anything past his return to the Island? Shouldn’t that be a big tipoff for him that something is going to happen to him/the notebook?
Does (older) Eloise later rip pages out of the notebook before passing it on so that Daniel misses some crucial information? Was the notebook empty when she first gave it to him, or already filled in? Where does a physical object like a notebook even COME from if no one ever buys it from a store at any point?
