Tonight's episode of my favorite show LOST was one of the best I've seen since the start of the series. In the first season, we saw John Locke as one of the most interesting characters. As the seasons worn on, his character seemed to change as he tried to find his way. Once Locke knew his purpose, he was unwavering - some might call him a zealot or obsessed. I find it compelling that Locke's character has a messianic quality - the note to Jack is interesting. It seems like something Locke would say. But now that we know he was killed by Ben (who should never be trusted) - did Ben write the 'suicide note' or did Locke write it before Ben stopped him mid-hanging? What prompted Ben to kill Locke? Was it when he found out Jin was alive or when Locke mentioned the woman's name?

Who is your favorige character on LOST, and why?
