Good, but not great. This one is all about Desmond, Charlie, Hurley and Jin trekking through the jungle to get to a fallen pilot, based on Desmond's 'future sight'. But for obvious reasons he keeps the knowledge that Charlie gets an arrow through the neck. Desmond is under the impression that if he says anything it could alter the future and keep him from being reunited with Penny. In the end, it didn't matter. It's not her, but someone else all together. The other half of the episode was about Desmond's time as a monk. This was a wasted narrative for the most part. It only mattered that in the end it was how he came to meet Penny in the first place.
