Why "D.O.C." is one of the best episodes of Lost:
1. Patchy is alive!
2. The coolest fight scene yet! Jin kicks a$$!
3. An emotional and involving flashback. Even though Sun and Jin don't actually meet in this episode, we get more insight into how much they love each other.
4. A shocking ending. They found the plane? There were no survivors? What???
5. Juliet gets more development as well. "I hate you". She's going to betray Ben!
Honestly, this episode was just plain fun to watch!
