I was slightly torn for a moment as to which is really the more brain-warpingly bizarre scenario: a world wherein Ben Linus says the eulogy for John Locke, or whatever AU fanfic it is they're apparantly writing over in the flash-sideways timeline. (I guess it wasn't just "a world where the plane didn't crash". It's the "if it weren't for those meddling kids Jacob" world.)
And then I realized - you don't have to choose. Because it's Lost!
...Also, Sawyer-becomes-the-new-Jacob fanfic is being written by somebody out there right now. Yes, I will bet money on this. Come on.
