Has anyone already found an answer, why Kate is so eager to leave the Island and to return to America? She is a known fugitive, facing a prison sentence. I don't understand why she is willingy leaving the Island. Okay, despite the threat from the Others in the first season and a monster living on the Island, it seems a nice place to live. And then, at the barracks they even have proper shelter. So why leaving it all behind? The made several attemps to leave or preparations for it. She wanted to use the ID of that drowned woman, poisoning Michael to get on the raft and joining Jack as the freighter people arrived.
For me, this seems like a legal question. Feel free to comment or to tell me where I find the answers.
