Juliet

I am doing yet another re-watch, and I just realized how much I miss her. She seemed like such an important key. It was like she knew so much and was always just on the verge of spilling her guts completely. But what bothers me the most is that when she was with the Losties when they were traveling through time and stopped in the 50’s and the others are speaking in Latin, and she tells them that it is Others 101, why does she call them others, she was on of Them, why do we not ever know what they call themselves (and please don’t quote Locke from season two (we all others to someone)?
Another thing Desmond knew a lot too and never really spilled the beans, he watch Inman make that map, when Sayid takes the boat from him at the end of season 2 and says he is headed to the north shore, he says, “oh, going to see the hostiles are you?” Maybe he just heard about them from Inman but why he believe him about that after he lied about the need for those injections and the quarrantine?
