So why did Molly die?

because she was an annoying bitch and the world is a better place without her. best part of the movie actually.

It's odd because the movies are so "destiny" driven, but I think this is purely and simply a joke to punctuate the movie.

Like the way everything works out, after all the work they put it, you're conned into thinking we got a happy ending for the characters... Then BAM! The rug is pulled from under them and they had the incredible misfortune of happening across an identical situation.

Rest in Peaceful Oblivion, Roger Ebert. June 18, 1942 - April 4, 2013

It would have worked better if Molly was the one with the reason to go to Paris instead of Sam and part of the twist was that she was always meant to board Flight 180.

A few theories:

>Just because Sam doesn't see her die, doesn't mean she didn't

>She was meant to die on Flight 180 (but that means she was going to go to Paris all along, even after everyone died on the bridge collapse)

>She was collateral damage

I believe the only utmost straightforward & simple answer for her death is; she was always meant to die on Flight 180 with all the rest of the passengers who were also on death's list.

That's how it happened.

Molly only died because she decided to go to Paris.
she didn't die on the bridge because she made it to the "stable" end.

idk but the ending isn't as clever as the movie thinks it is.
