Well i wish i could even put my thought together with this episode but Sayid episode are always crazy you just knew what he's going to do, i mean when he goes meet flock and stabs him , the look on his face was funny and than he goes back kill those two other people in cold blood for no reason so that he could let flock in. So in the end the guy was right Sayid has gone to the dark side?.
What do you expect you can't really blame Claire for going crazy can you?, she been all alone in the jungle for 3 years.
. As for Sayid he has too many demons so no surprise why he gone a bit crazy.
Question: why was Jin locked in fridger ?
