Does drinking all the time make your skin bad, and other thoughts from Lost

First things first: I screamed out loud twice during the last two minutes of Lost. I'm sure those of you who watched know when. I am still in shock. Is Michael brainwashed? Did he think he had to let Henry return in order to get Walt back? What in the world is going on?!

Now that that is out of the way: It's hard to mask flaws on a 50 inch widescreen plasma HDTV. And if your skin is as bad as Michelle Rodriguez's, it is really, really hard. During this week's episode I was totally fixated on her chin, cheeks and forehead. The entire surface? Covered in zits, which were covered (insufficiently) with makeup.

I'm sure there are a lot of actresses with bad skin--all of that makeup they wear has to take a toll. But I have never seen someone's imperfections so magnified. Does alcohol consumption hurt the skin? Remind me never to hit the bottle the way Rodriguez does (for more reasons than just my skin).

Oh, and did anyone notice Libby had a yellow front tooth in this episode? I remember Cynthia Watros when she played crazy Annie on Guiding Light (now she plays crazy Libby on Lost...interesting), and I remember a nice set of white teeth. So I assume this is just part of Libby. Why hadn't I noticed earlier?

Anyone have any ideas who Jack's half-sister is? Claire? And how creepy that when his father had to come up with a name for Ana-Lucia he chose Sarah--his daughter-in-law's name.
