Just watched the ep, and I gotta say, for 2 characters that weren't even supposed to be regulars, this was a good ep.
Maybe in Season 3, they can have more backstories, maybe even before they met eachother. Hey, if they can give Locke a full head of hair, they can surely afford to give Bernard a little hair dye.
Some off similarities to season 1 I've noticed. Last year, right before the Recap episode, Do No Harm aired (the episode where Jack tries to save an injured Boone, but Boone dies). Now, in S.O.S., at the very end, Michael stumbles in, looking possibly injured, or just possibly tired from yelling WAAAAAAAAALLLLLLLLLLLTTTTTTTT for 7 episodes straight. Obviously from the previews we see that Michael doesn't die, but it's still similar, I think.
Also, last season, Boone and Locke were out in the jungle digging up the hatch opening. This season, Charlie and Eko are out in the jungle building a church.
Was that thing Sayid and Charlie were building a few eps back something for the church?
Finally, one last note. Fake Henry doesn't have any eyebrows. That creeps me out.
