David's mother is Sarah. But the fact that we haven't heard anyone call her by name yet and haven't seen her brings up some interesting questions about her identity. It could be that they couldn't get the same actress, but then they'd still say her name when talking about her and to her via the phone.

below decks 5 days before fending off the wild boar. The Smoke Monster appears as Isabella on day 6.

releases Ricardo and says 'it's good to see you out of those chains' - the same thing John Locke says in "LA X". This explains Richard's expression when he hears Locke say it.

instructions and dagger given to Ricardo to kill Jacob are identical to those given by Dogen later. It's his first attempt to use the loophole he later used in the season 5 finale.

leave the island while Jacob was alive, and he couldn't leave after Jacob was dead due to the presence of the candidates - hence his apparent interest in taking them with him

whether MiB cannot leave the island without all the candidates - though it seems reasonable

Island - The Losties face off each other and then are let into the group. Jack sees 'Locke' for the first time and sits down to talk with him. Notice Jack cradles his rife all the while? He's willing to listen to Smokey but he doesn't trust him (not that a rifle would do much against him, but it's the thought that counts, right?)
Smokey tells Jack that he appeared to Jack as his father, Christian. Is he telling the truth, a lie, or a partial truth? I'm leaning towards a partial truth. At times he may have been Christian but I have a feeling it was Jacob that led them to water etc.

LA X - Following the accident, Locke is rushed into an ambulance, Ben hops in alongside him. Locke mentions the name Helen Norwood. I'm guessing we'll see a scene where she's notified of the accident and comes to see him at the hospital.
Sun awaken in a stretcher, as does Locke. She recognises him and screams. But does she recognise him as Locke or Smokey?

Island - Claire and Jack finally talk. Thankfully, she seems to be more herself. It's a lovely moment between siblings but then she seals her loyalty to Smokey with the comment, 'Jack, you decided to join him, the moment you let him talk to you'. Creepy!
Sawyer tells Hurley of his plan to leave the Island using Widmore's submarine. Hurley gives a Star Wars reference and Sawyer doesn't seem to recognise it. Is this an error, or is he just too flustered to bother with trivial pop-culture references? I'm hoping it was the latter.

LA X - Sawyer and Kate are at the police station. Sawyer eats an apple. Is he just hungry, or are the writers hinting at an Adam and Eve connection with the two? The forbidden fruit in the Garden of Eden wasn't necessarily an apple, but the belief that it was has entered public consciousness. Miles enters and notifies Sawyer of a murder suspect leaving Keamy's restaurant and about a non-English speaking witness. It doesn't take a genius to work out that he's talking about Sayid and Jin.

Island - Zoe enters Smokey's camp, demanding to speak with Smokey. She tells threatens them and orders an air strike to frighten them. Zoe and Smokey don't flinch but it freaks out everyone else.

LA X - Claire heads to the Adoption Agency but Desmond intercepts her and talks her into going to see a lawyer he knows. Desmond is decidedly creepy here - very much a stalker. If I were a young, single woman, I'd be especially disturbed. His lawyer is on the same level as the Adoption Agency, Level 15 (Sawyer's number). There we meet Ilana?! She has an American accent and seems to recognise Claire, possibly from the Island.

Island - Smokey tasks Sawyer with getting a boat on the shore to take them and Locke to Hydra Island. He gives him a rudimentary map to help. Sawyer uses the map to clue Hurley into his plan. Sawyer wants to help the sane Losties all escape on the boat, so they can find the submarine and escape from the Island. Meanwhile Smokey tasks Sayid with killing Desmond. I don't think he went through with it.

LA X - Sayid returns from Keamy's restaurant to Nadia's house and packs his bags to leave. Miles and Sawyer turn up to arrest him. Sawyer pulls a fancy garden-hose trick to trip up Sayid.

Island - Sawyer takes Kate and they find the boat. Smokey goes off to talk with Sayid and the sane Losties leave the group. Sayid returns from 'killing Desmond'. He seems to have a bit of a soul now. Talking to Desmond must have done him some good.
We witness Kate's loyalty to Aaron and Claire when she refuses to leave Claire behind with Smokey and has a great talk with her. She admits that she shouldn't have raised Aaron. Good stuff! The Losties all climb aboard. The boat looks very familiar - it's the Elizabeth, the yacht Desmond sailed to the Island in. More precisely, Libby's dead husband, David's boat. Awesome!

LA X - Jack and his son, David arrive at the Law Office (?) and they go to Level 15. Hmmm... This is for the reading of Christian's will but wow, Claire is there also and she's been expected. Desmond has shepherded her where she was meant to be! They discover that they have the same father. Jack is disturbed by it all, gets a phone call for an emergency at the hospital. He has to leave, so he reschedules for the reading of the will.

Island - The Losties sail the Elizabeth to Hydra Island. On the way, Jack and Sawyer have a disagreement (really?) and Jack jumps off the boat. Sawyer acts like a baby and Jack is now a man of faith. He doesn't want to return to LA where his life will be hellish. He believes they're there for a reason and that they have a job to do. Sawyer is peeved because he just wants to get off the Island. I commend Jack for his decision.

LA X - Sun survives surgery, as does the baby. Jack and David make their way to the hospital, where Jack will perform emergency surgery. David's okay with waiting X amount of hours for his dad to finish work. What a patient kid! Emergency surgery would take, what, six hours minimum? I find it funny that dural-sacs are mentioned so often in the show. It's like it's the only medical term the writers know. Ha, hilarious! Jack's patient is none other than Locke. Wow, I didn't see that one coming.

Island - Jack returns to the Island where Smokey and his crew are waiting. On Hydra Island, the other Losties are taken captive by Widmore's crew. Sun and Jin are finally reunited and a lovely reunion follows. Unfortunately, it didn't have the impact it should've after several years. Maybe we didn't care about these two characters as much as we used too, maybe the writers delayed it too long and maybe it was cut short. Either way it was a nice moment but surprisingly anti-climatic and short-lived. I have a disturbed feeling that Sun and Jin won't be with us much longer.
Sun regains her English voice.

So the Island or the MIB takes away her ability to speak English to punish her. When she's reunited with Jin, her speech returns because her doubt has disappeared and she has found her love again.
Zoe orders an air strike on Smokey. There are lots of lovely explosions and Jack and many red-shirts are blown away by a blast but only he seems to survive. Smokey picks Jack up and runs for cover. He tells Jack, 'you're with me now!'
Chilling. So Jack is The Last Recruit, but will he also be The Candidate?

I cannot remember the exact episode but I do seem to recall that during Season 2 (I think it was "What Kate Did", but I cannot remember for sure) Kate saw a horse on the island. Given Smokey's ability to morph into important persons from the characters' pasts was the horse actually Smokey? I didn't get a "bad" vibe about the horse like I got from all the other manifestations, but then again it might be because it's an animal and one might not look at it that way...

Smokey.

MIB

First things first: in the island timeline, lots of death: Sayid dies a hero’s death, hoping to save the others in the sub. Jin and Sun both drown in the downed submarine (I understand Jin’s reluctance to leave his wife, but what about a parent being there for little Ji Yeon?), Kate has been shot – with little prospect of even a first aid kit to help out, and Sawyer is unconscious after a serious blow to the head. Whew!

We find out that Flocke wants all the candidates so he can kill them so he can leave the island. He tells them that Widmore wanted them all on the plane, in a small enclosed space that they could not get out of, in order to kill them all at once. Then he does it with the sub.

I think he planted the C4 on the Ajira plane so he could arrange the whole submarine con. At the end, he goes off to finish what he started – to kill the candidates that survived the sub sinking.

Jin and Sun have a touching final scene, and they’re still alive in the alternate reality, but still, to see them die is…just sad. Maybe the emotional depth of the scene will grow on me. (Yes, I’ve read those spoilers that indicated there would be a lot of death – including characters we’ve come know and love).

had some nice touches. Jack meets Bernard (nice to see him again!) to talk about John Locke's background. Several characters find it interesting that all of them were on Flight 815 - like they're beginning to put the pieces together.

John knows about the island reality somehow (in his sleep/dreams/delirium he talks about “pushing the button” and repeats his “I wish you’d believed me” line from season 2).

In this reality he loves his father “more than life itself” and bears immense guilt over Cooper’s injuries in a plane crash John piloted. Jack repeats “whatever happened, happened,” at one point, as well as “I wish you’d believe me” back to John.

At the beginning Jack calls the injured Locke "a candidate" - for spinal surgery but also as a word play to Jacob's island candidates.

For starters I knew that Sayid, Sun and Jin were going to die, but to actually see it was really sad!
I’m glad Sayid redeemed himself, and did what he did to save everyone else! And to have it confirmed that Jack is the candidate was assumed even though I figured it was him.
I bet Jack was right when he said not to do anything, that everyone would have been ok.
I nearly cried when Jin refused to leave Sun, even though he knew it would end with them both dying.
I’m glad that if they had to die, it was together, even though it was sad!
I am so exited for the next episode!!!! I’ve heard that they are going to explain a bunch of stuff, I hope they are right!!!!

This episode reminded me of a little bit of Season 3, it was powerful and sad!

Lost writers, you are dead to me.

That is all.
