I know what you mean. I love Charlie and I'm really liking the story between Michael and the kid (his name escapes me at the moment). The character development is really good. Although, I must say, I'm not happy with the way Kate has gone. I dunno what it is exactly but I used to really like her and now not so much.
I like Michael and his son (Walt? Or is that the dog?), Jin & Sun, and Claire a lot. I see the most potential for deep characters there. I'm a little over all the emphasis on some of the others. I wasn't crazy about Shannon before, but I like her more since Boone was killed. Maybe it's seeing her take care of the dog; I don't know. Charlie is another of my faves -- I can't believe he took the heroin/nun!!!
But there's a bit too much Kate & Jack & Locke for me.
I've been exploring
www.tv.com and found out the following:
Claire named her baby Aaron, which was Moses's brother's name ... this ep was titled Exodus. (They've also been on the island for 40 days)
During the Hurley flashback, those numbers appear again. His hotel room is 2342. On the panel of his rental car the numbers appeared again: 42km, 16kph, 23 deg. On the screen of the Oceanic Air computer: "Arrival 1?:42." A group of (volleyball? handball?) players with numbers on their shirts: 4, 8, 15, 16, 23 and of course 42. The big sign "Gates 14 thru 23", "Gate 23" and, last but not least: If you look closely, you'll notice exactly 42 people standing in the line where Hurley tries to pass through.
People think about this show way more than I do!
