This is the episode we find out the big bombshell that Christian Shephard has TWO kids on that island. It's a bloody family reunion! Claire had been told her father died when she was two.

Mikhail tells his captors that the Others can come and go as they wish, but with the underwater beacon not working, the sub can not currently bring anyone in. Kate doesn't understand. Why would she? She's not ready to. There are things too big or implausible for the mind to wrap around until they are revealed slowly. She asks Mikhail:

Why would you want to come back?
You would not understand.
Try me.
I misspoke. What I meant to say is, you're not capable of understanding.
And why not?
Because you are not on the list. (Ohhh... I wasn't even thinking of that as the reason. I was just going with Kate have no faculty to assume for a second that this island is special and there are people who love it and war over it and would give anything to get back to it. But Patchy begins to talk about Jacob (without mentioning him by name) as "the man who brought me here, who brought all of my people here. He's a magnificent man." She assumes he is talking about Ben. No. Mikhail explains to Kate that she didn't make the list because she's flawed. Locke's angry. And Sayid's weak and frightened. And he knows all of their names. Seems confused as to why Locke's not paralyzed though. He gets interrupted before he mention that further, as Danielle has found the sonic fence.

Mikhail tells Sayid he has guessed correctly - the pylons are a security perimeter. But he lies when he says it hasn't functioned in years. I say he lies because, even though it has occurred to me he could have faked his seizure and pretended to be dead, it would have been hard to fake the very obvious sonic sound effects we get, and the ear bleeding he experiences. Locke decides not to waste any more time or bother with Mikhail's games. He forces Mikhail through the fenceline, which I think is a brilliant decision. Either we learn Patchy was telling the truth and the fence is off and he was just stalling them because it's safe after all, or he will be fried and they will be rid of a captive who it has already been established is of no value to them while being extremely dangerous to them, and they'll know what they need to do. Kate and Sayid do not see it this way, however, after watching Mikhail cook. So strange, though, that Mikhail says "thank you" just before he buys it. Again, is this because he wants to die, or because he can't be killed and so Locke has just set him free?

When arguing why Locke pushed Mikhail into the fence, Sayid asks Locke why he's there. Is it for Jack? Why else, says Locke. Sayid says they'll discuss that later. He also lets Locke's lie about why he took the C-4 go on hold until later. But we can discuss Locke's motives now if you like. Why IS Locke there? We know his motives once he learned about the existence of the submarine. And originally, he very much intended to help find and rescue Jack, and I don't think that's changed. But more than anything, I think he just wants to see where Eko's Jesus stick clue leads him, where the island would have him go.

Kate is the one with the idea to build a tree bridge over the fence. She tries it first, and makes it fine. Examines Mikhail's body. He sure looks dead.

The Note Claire Writes to Attach to the Bird:

To Whom it May Concern,

We are survivors of Oceanic Flight 815. We have survived on this island for 80 days. Six hours into the flight, the pilot said we were off course and turned back towards Fiji. We hit turbulence and crashed. We've been waiting here all this time, waiting for rescue that has not come. We do not know where we are, we only know you have not found us. We've done our best to live on this island; some of us have come to accept we may never leave it. Not all of us have survived since the crash, but there is new life, too. And with it, there is hope. We are alive. Please don't give up on us.
