Top episode, i'm gripped! The preview for the next episode was interesting too, although sadly it showed no progress following the storylines in this episode.
Jack is really good, gotta feel for him with the "miracle worker" tag and naturally drifting apart from his missus who cheated on him. It shows that he doesn't want to have kissed Kate then see her go off with Sawyer.
The bearded man in the jungle was a tense moment, i was surprised to see him! The power those guys obviously have is pretty disturbing, i can see another survivor dying before the series is out perhaps? They surely won't last long before killing an unwanted visitor...
I believe the "Others" are training in an underground bunker not too dis-similar to the Hatch, a base with computers hence Walt's JungleMSN convos and Michael's clear path to a single place. But what is twisting my melons right now is are the Bearded Guy & Crew actually part of The Others? Maybe they're two different clans, maybe who stay out of each others way, or not.
If not an underground bunker, maybe another island? It would explain why the kidnappers were out at sea
