The comment I write will be for "The Incident" (Part 1 and 2), because it is a two-in-one episode as usual for the season final.
This episode again reveals some of the long hidden secrets, as for example, what is behind the wall of the hatch(season 2), who is Jacob, why does Richard Alpert not age, how did Locke come to life again after Ben killed him. And at the end of this episode there is a cliffhanger, similar to the last seasons, which will make the time waiting for season 6, quite long. What happened after the detonation of the hydrogen bomb? Will they be at LAX? Or still in 1977? What happens after Jacob's death? We are left with questions again, but that's what I love LOST for. See you in some weeks/months.
