I should point out another Lost connection. The collected notes are a reference to the Pearl, the Dharma station where "observers" would studiously take notes in journals. Those journals were sent through a pneumatic tube, ostensibly to be collected and studied, but it turns out they just fell out into a pile in the middle of nowhere, never to be read by anyone. (And the observers were actually the ones being observed.)
Kevin's justification of why he was pretending he didn't remember anything since they met makes little sense. The reason is so people watching will be all "OH What's going on here?! Is she in another dimension? Did Kevin just travel here? This is a MYSTERY!"
You know what, I will actually give you that point, because I thought the same thing.
At the same time, I love being trolled by Damon Lindelof and have for a long time. I think it's an acquired taste. In Season 2, when Patti actually started singing "Never Gonna Give You Up," I basically exploded with joy.
If she was lying, "the better story" doesn't sell me. She was too emotional, she definitely believed the story. We have never seen such amazing lying if she were lying.
That's a fair point too, but I'm willing to accept it as an imperfection of producing this thing.
I think Nora would have had all the time in the world to dream up this story. She seems to be living with a sense of shame. (Shame that she couldn't go through with it.) She seems to have lost a lot of dignity. Maybe she's even started to believe the story.
The idea that her family are actually the lucky ones on the other side seems like a fantasy that might have been on her mind for years as she wondered what happened.
Yes, Nora is stubborn. But that is a characteristic, not a certainty. All the time, people make choices that don't exemplify their traits. Nora might have been swayed by another of her core traits — skepticism. And that might have saved her.
