3.75 to 4/4 Excellent episode! So much happening!
My only complaint is that I was hoping this episode would be more revelatory about Richard, since I was spoiled on the fact it was his episode... but it was more of an ensemble episode.
Too bad we didn't see what's going on with the Ajira camp. Remember the bit about the secret codeword from forever ago?
So Locke wants to kill Jacob! I did not see that coming! It makes sense in retrospect, since Locke thinks that Jacob has been keeping the Natives under his cruel thumb all these years. But how do you kill a poltergeist? Can't wait to find out!
Finally, finally, we get confirmation that yes the Others have extensive tunnels running throughout the entire Island. Boo yah! It's a little crazy that they had to swim though a super long water tunnel to get in, though. Surely there are more convenient entrances, like the one they used to put Jughead in there.
Interesting to see Radzinsky overthrowing Horace like that. I can't wait to see how this ends up with Rad stuck in the Swan all alone, the lone (loyal) survivor of the Dharma Initiative. Again it's a shame that Hanso and the DeGroots are nowhere to be seen.
Kate's last minute appearance on the sub was absolutely hilarious. Sawyer and Juliet have this big touching moment where they're gonna live happily ever after... then Kate is literally shoved between them!

Ah, the look of horror on Juliet's face! I love it. Do the writers intentionally make Kate as annoying as possible???
Loved seeing Ben as Locke's loyal acolyte. Great stuff. I wonder about Richard's loyalties, though. Is he really going to help Locke to kill Jacob? Hasn't he faithfully served Jacob all these decades/centuries?
Also loved Hurley stuffing a sack full of Dharma tinned food before not-so-subtly slipping off into the jungle
Should be an excellent finale!
