I have collected evidence for the loop theory.
Sawyer: will kill himself infront of himself.
Jack: will get Sarah and this is why he lost Sarah in the first place.
Hurley: will speak the numbers and this is why he won the lottery with them.
Kate: will end up alone, running. Her name is not Kate.
Locke: will be in the coffin of Jack's father when Oceanic 815 crashes, so he will be box-man for the third time!
Dharma-stations: named after star-constellations. when you put a map of the stars above the map of the island you find each station at the responding constellation! (for orientation purposes!)
