It occurs to me that with the exception of Kate, everyone is better off in the flash sideways world. 1) Claire is not crazy in flash sideways
2) Sawyer has a good job and some sanity in his life
3) Hugo is the lucky guy
4) Jack seems to have a good life with a respected medical practice and a nice son
5) Ben is not a devious worm and may about to get a nice family
6) Pretty much everyone (Locke, Son, Jin, Charlie, Boone, etc) else is alive and not dead.
I wonder if that is a sign that the flash sideways world is where everyone but Kate lands up?
