I've been rewatching alot of episodes as well, but frankly I find Desmond's character extremely boring and I think "The Constant" was highly overrated.
But everyone is entitled to their own opinion, so I'll keep sticking with Ben because the more I watch the more I know he is one of the good guys and things are finally going to get serious in the next 2 seasons. I just wish he would kill Jack and the rest of the Losties (well except Sawyer, Hurley, and Locke) and be done with them instead of focusing on Penny. But now he needs them to get back to the Island...god I hate Jack and Kate and Sayid and Sun etc. etc.
