1. Jin is pregnant. Some have suggested that it would take upwards of 6 seaons for the baby to be born, given the pace of the show already. BUT, I contend that it IS possible she was pregnant before the flight.
It's not uncommon that in times of stress and trauma that a woman's...cycle...will be interupted and Jin could have dimissed a lack of ... time of the month on that. But perhaps, now that we're into the second month on the island, she is starting to think it's more than just stress and that she's really 3 - 4 months pregnant.
Evidence suggesting he is an other is the fact that he was taking / had access to the vaccine injected in Claire. When he took off, people were wondering just where the heck he went. Well, maybe he went to another "Others Hatch" which explains why there has been neither hide nor hair of him since he bolted.
3. Henry Gale, no doubt in my mind, is an Other.
But some are chastizing Locke for "falling for the oldest trick in the book". Uh...can you blame him? Look how his real father played him like a fiddle...it's possible that Locke has always been susceptible to being tricked.
Other general comments.
Mr. Eko, unequivocally, scares the hell out of me.
Some people complain that Hurley (and others) ain't losing weight. Look, all in all it's a T.V. show -- we can't expect the actors to have to undergo weight loss like we see on Survivor. You want emancipation? Watch CBS tonight at 9:00 local time for Exile Island!
