I liked the episode till I started to think about it
If their not these Island rats, why are they so damn good at tracking and such. Ethan is a doctor and a ninja-tracker-executioner now too? I agree that their not "The Others" as we previously thought of them, but the whole super-human thing seems odd now.
anyways, The bit about Locke freaking out was HORRIBLE. 8th graders write **** like that. Early on they tell ecko that they guy is "smart". Then Locke falls for the old Bugs Bunny "So why is he the boss, you're the smart one" trick. Whats next, the guy is going to paint a tunnel on a wall and Locke will run into it? Terrible.
Also, if I'm being held in a cell and a Ecko (sp?) walks in after checking his club at the door, I piss myself. He then pulls a knife out, I piss a little more.
