I've tried to figure this out but it is very confusing.
Jacob's side: Ilana and Richard are the only ones i can think of for sure. I think also Charlie,Boone and Ana Lucia.
Not quite sure as to which side Christian,Widmore,Eloise and even Horace are on.
Couldn't really guess who is actually on MIB's side. People that are might not know they are.
Then you got the wild cards: Desmond,Claire and Faraday
And what about the "Sherrif" the others had, i forget her name.
