Ever since Shannon took a bullet to the belly, it’s been something of a running joke amongst fans of this show that sex equals death. Well, tonight we got concrete proof that it’s not just a joke among fans — it’s freakin’ deliberate.

Juliet confirms that women who conceive on the island die, usually by the middle of their second trimester, never later than the beginning of the third. And Sun, we learn, was impregnated by Jin…on the island. (Yeah, we learned his swimmers don’t swim a while back, but tonight Juliet rather casually informed us that sperm production is up five-fold on the island. Which makes me think that Dharma’s missing a bet with all this cloak and dagger stuff — they should just rent out the island to infertile men! Let them come here for a hefty fee, impregnate their wives, then go home to deliver safely. Lot more money in that than in terrifying helpless castaways.)

Where was I? Oh, yeah — Sun’s gonna die. Bummer, huh?

Actually, though, I like this plot development. It adds a ticking clock to a show that’s been woefully missing one for a while. Now there’s a compelling reason to figure out the island mysteries and get off the island as quickly as possible. (Other than, y’know, just wanting to get the hell of the island in the first place!)

Further in the “answers revealed” category this week, Mikhail reveals that–

Wait a sec.

Mikhail?

Shoved-through-the-sonic-fence-by-Locke, blood-spurting-out-his-ears, foaming-at-the-mouth, “He’s dead, Jim,” Mikhail?

Um, yeah. He’s back. With no explanation. Which is actually fine because it was such a complete shock to me that I prefer it go unexplained for now.

Anyway, he reveals that, yes, the island does have mysterious healing properties. Yeah, we’ve known that for a while, but now someone has told the castaways in no uncertain terms.

Things like this, coupled with Juliet’s comment on sperm production, make me think that maybe the producersare going to start doling out the answers a little bit. Stranger things have happened, I guess.

In the flashbacks… Um, we learn that Jin and Sun love each other a lot. (Which we knew already.) We learn that Sun is a hard-core bad-ass. (Which, uh, we knew already.) We learn that Jin’s mother is/was a prostitute who blackmailed Sun. (Which we didn’t know already, but which was telegraphed really badly.) And we learn that Jin’s dad keeps $100 grand in cold, hard Korean cash in his safe and doesn’t mind punching in the code while his daughter is standing there.

Which we didn’t know. But, uh, does anyone feel enlightened by that knowledge?

So, back on the island, Juliet leaves Ben a love note, saying, “I hate you,” which is nice. And Lady from the Sky gives us a great cliffhanger when she reveals that Oceanic Flight 815 was found…and there were no survivors. Ooh… That’s enough to keep me coming back next week, kids.

But…

When Juliet takes Sun to the Caduceus, I couldn’t help thinking, “Why haven’t the castaways moved in here yet? It’s safe; it’s dry; it’s got electricity.”

Which, of course, brought me back to my same old bugabooWhy in the name of all that is holy and good and righteous haven’t the castaways moved to Otherville yet? Jesus! Someone, anyone on the writing staff, PLEASE throw in a single line explaining this because it’s killing me! Of all the lame-brained things the castaways have done on the island, this is surely the stupidest. And every time an episode goes by without an explanation, a little piece of me dies.

And that’s just sad.
