Jacob lays Mother & MIB's bodies to rest at the caves, they are Adam & Eve

Jacob makes his way through the jungle to a stream and washes up. He looks up and sees the lifeless body of his brother on some rocks. Jacob weeps over the body, then picks it up and carries it to the cave.

Jacob lays MIB's body where they slept as children. He then goes to Mother's body and picks up the black and white stones and places them in a pouch. We cut away and see Jack and Kate discovering the pouch of rocks in season 1 with the "Adam and Eve" skeletons.

Jacob then closes Mother's eyes, picks her up and lays her next to MIB's body. We again cutaway to season 1 and Kate asks who the Adam and Eve skeletons are and where did they come from. Jacob then joins Mother and MIB's hands, kisses the pouch containing the stones and places it in MIB's other hand. We cut away again and see Locke calling the skeletons "Our very own Adam and Eve."

We then see Jacob looking over the bodies, still crying, and he says "Goodbye brother."

This was one of the biggest reveals of the series. While the clips from the season 1 episode "House of the Rising Sun" hit us over the head a bit with the significance of the Adam and Eve reveal, it did show us how far the story and these characters have come since Oceanic 815 crashed on the island.

With MIB's body being discovered by the creek indicates he is no longer human, but he still has the same goal of leaving the island. What would happen if this creature gets off the island?

MIB wrecks the caves, stabs & kills Mother, Jacob pummels MIB

As Mother and Jacob make their way back towards the caves, Jacob says that there is a storm coming. She tells him to go gets some firewood before it rains and tells him to be careful. Jacob says that he'll see her back at home and leaves, but clearly seems to Mother know they won't see each other again.

As Mother returns to the cave, she finds that it has ben ransacked, including the tapestry which is ruined. She discovers the Man In Black's Senet game on ground and removes a black and white stone from inside. As she examines the black stone, MIB plunges the dagger through her back and she falls to the ground.

MIB leans over her body and asks why she wouldn't let him leave and she says "Because I... I love you." She then says "Thank you" as she dies. He weeps over her body and then sees that Jacob has returned.

Jacob repeatedly asks MIB what he did and then leaps forward and attacks him, much like he did as a teenager. After pummeling him in the face he finally stops. We'll pick this up in the next post.

So Mother seems to have the same feeling about her death as Jacob did when Ben stabbed him. They both didn't fight their deaths and Mother even thanked MIB. Why is that? Is it just their time to move on after thousands of years of performing their job?

Mother takes Jacob to The Source/The Light, passes her job on to him

Mother returns to the caves at night where Jacob is sleeping. She wakes him and tells him "It's time." She leads him through the jungle and as they're walking Jacob says that "Something happened, didn't it?" She tells him that she had to let MIB go because she doesn't have a choice and it's what he wants.

As they reach a stream, she asks him if he recognizes where they are and he does. It's the stream that leads to The Source, the tunnel of light. She passes Jacob the torch, literally, and tells him that he must protect The Source now.

Jacob asks what's in the tunnel and Mother says that it's life, death and rebirth, the heart of the island. She tells him to never go down there because what will happen would be much worse than death.

Mother then pulls out the bottle of wine (the same one from "Ab Aeterno") and a cup. She chants in Latin was has been deciphered as "Nam non accipimus hoc quasi vulgarem potionem, sed ut ille sit quasi unus mecum." That roughly means "For we do not accept this just as a common drink, but as if that (he?) should be one with me."

She pours some wine into the cup and tells Jacob to Drink. She says that if he drinks, he accepts the responsibility of protecting the island as long as he can, and then he'll have to find his replacement. Jacob says that he doesn't want to protect the island. She says that someone has to and Jacob says that he doesn't care. She says that her time is over and it has to be Jacob that takes over.

Jacob gets emotional and says that he doesn't have to be him because she wanted it to be MIB, and now "I’m all you have." Mother says that it was always supposed to be Jacob and she sees that now and one day he will too. She adds that the doesn't really have a choice though, so he must take the cup and drink.

Jacob reluctantly takes the cup and drinks. Mother then takes his hand and says "Now, you and I... are the same."

So we see that Mother essentially forces Jacob to take the role of protector of the island. She says that he doesn't have a choice, which likely led to Jacob's view that everything is a choice, which he told Hurley in the back of the cab in "The Incident." Jacob has always seemed to push people in a certain direction, but never forces them to do anything. Jacob seems to do many things differently as the protector of the island.

MIB shows Mother his path to the light, the donkey wheel, she knocks him out

Jacob returns to the caves and Mother asks where he was. He says that she knows and she asks what the Man In Black said to him. Jacob tells her than MIB finally found a way to leave the island. Mother looks terrified.

Mother makes her way across the island to the work site of well. She watches intently as the men and women pack up and leave. She then heads down into the well.

Down there, we see MIB standing over a fire and we he hears something, he turns quickly wielding the dagger. We he sees that it's Mother, he puts it back on his belt. He has her how she is and Mother says that she's worried. He says that she should be and that he spent 30 years covering the entire island looking for the source of the light at the tunnel she took them to as a child, but could never find it. But then he says he figured out that he could get to the light from another place on the island an finding that place took a long time.

Mother worriedly asks if his people saw this too and he says yes and that they have interesting ideas about what to do with it. She starts to say that he has no idea about something but he interrupts her saying that he has no idea because she wouldn't tell him.

MIB then uses a tool to pull a small stone from the wall behind him revealing a beam of bright, yellow light. Mother then notices a large wheel leaning against the wall and asks what it is (it is the infamous wheel that was frozen when both Ben and Locke turned it). MIB says that they are going to cut a larger hole into the wall and attach the wheel to a system they are building. The system will channel the water and light, so when he turns it, he will be able to leave the island.

Mother asks him how he knows this and he says that he knows because he's special. She begs him not to go, but he says he has to because he doesn't belong there. Mother says that this is goodbye then as she steps towards him and embraces him. During the hug, MIB seems content and  tells Mother goodbye. Mother releases him, grasping his face like she did when he was a child. She says "I'm sorry" as she slams him against the wall, knocking him out.

Geez. There's so much here. There is the origin of the frozen donkey wheel and a vague description of how it is intended to function. We learn that the light we saw in the tunnel earlier is the same as is found in pockets across the island. We also learn that MIB seems in tune with the island on an amplified level that he is able to deduct intricate things about's function. We also see that mother is afraid of any humans learning about the light, which we'll see the results of in a later post. Heavy, heavy stuff.

MIB is visited by Jacob, shows him magnetism at a well, tells him people are bad

When we return for Act 4 of the episode, we jump forward 30 years and we see Jacob as an adult at the caves working on a tapestry. Mother sits close by pressing something in a mortar with a pestle. She seems distant as Jacob turns to her and asks her what she thinks of his tapestry. She says that it's nice, and when he asks is she is alright, she says she's just tired.

It then cuts to a work site on another part of the island, where the other people are working on a well including the Man In Black (this is the same well that Locke fell down in season 5 to leave the island that is near the future sight of the Orchid Station). Jacob watches the site from a distance and Man In Black sees him.

Later, after the workers have gone, Jacob and MIB sit nearby playing the same Senet game from their teenage years. As the play, MIB asks Jacob if Mother knows that he visits him, and Jacob says that she never asks about him. MIB bitterly says that he's sorry he asked about her then.

He then asks Jacob why he watches his people and Jacob says that he wants to see if Mother was right about them being bad. MIB says that Mother may be insane, but she was right about the people being bad. Jacob says that they seem fine, but MIB says that's easy to say when you just watch them from a distance. He adds that after 30 years of living among them, he's learned that they are "greedy, manipulative, untrustworthy and selfish."

Jacob asks why he's with them then and MIB says they are means for him to get off of the island and they've found a way. Jacob says that is impossible because there's no way off of the island.

MIB pulls the dagger from his belt (the same one MIB gave Richard and Dogen gave Sayid) and throws it at towards the well. The dagger curves and sticks to side of the well. Jacob goes to the well and pulls the dagger from it. MIB tells him that there are smart men among his people who are curious about how thing work. He says that they have found sites all over the island where metal acts strangely and when they find these sites, they dig. He says at this site, they found something and asks Jacob to come with him.

MIB asks Jacob what he's going to do when Mother dies, and Jacob says she'll never die. MIB says that everything dies. Jacob emotionally says that he doesn't want to leave the island because it is his home. MIB replies "Well, it’s not mine."

Like so many scenes in this episode, this one is quite heavy. We see and hear about the digging of the wells, which Locke told Desmond about before pushing him down one. We see debate start about all men being bad and corruptible versus them having the potential for good (MIB's position versus Jacob's). There's certainly a lot to download and absorb.

It also seems that Mother may know that something bad is coming by the way she's acting at the caves. It's not likely that we'll ever know the full extent of the powers and abilities that the island's protectors have.

MIB is beaten up by Jacob after revealing the truth, leaves for the other camp

As Mother lays sleeping at the caves at night, Man In Black sneaks in and goes to where Jacob is sleeping. He wakes Jacob up and tells him to come with him.

A short distance into the jungle, MIB reveals that he has all of their things and they are going to leave and never come back. MIB reveals that they are going to the other people on the island because they are their people. Jacob strongly objects, reminding him of what Mother told them about the people. MIB tells him that Mother lied about everything and Jacob has to go with him because he doesn't want to go alone.

The argument gets more heated as MIB says that Mother doesn't love them and she's not even their mother. With that, Jacob snaps and tackles MIB, repeatedly punching him in the face. Mother shows up and Jacob stops, leaving MIB's face bloody.

Jacob tells Mother that MIB is leaving to go to the other people. MIB stands, spits the blood from his mouth and says that he knows now that there is another place across the sea that is where he's from. He says he's going to go home. Mother asks who told him that and he says his mother, Claudia, told him.

MIB says that Mother killed Claudia, who was Jacob's mother too. He asks Jacob again to come with him and Jacob says "no." Mother stops MIB and says that no matter what he's been told, he'll never be able to leave the island. MIB picks up his bag and heads into the jungle towards the people.

Why is it that at this point in his life, Mother is saying that MIB can't leave the island? She said they couldn't hurt each other, but Jacob beat up MIB, so does this mean she's lying about a lot of things? Either way, MIB picked his destiny early in life and is on the path that he'll follow for many, many years.

Mother tell MIB there is nothing across the sea, Jacob doesn't know how to lie

At the caves, Mother is working on a tapestry as Jacob returns (we see where he got his knack for tapestries). She asks him where his brother is and he tells her he is at the beach, staring out at the ocean. Mother looks at Jacob suspiciously. Jacob asks if he can help her and she tells him to sort some thread.

Mother asks what Jacob and MIB were doing at the beach. Jacob hesitates, and then says they were just walking. She turns to him and asks "Do you love me Jacob?" He says yes and then she asks him to tell her what happened.

We then see MIB sitting at the beach, looking at a sea turtle. Mother approaches, sits down with him and smiles. MIB realizes that Jacob told her about the Senet game he found. Mother says that Jacob does not know how to lie because he is not like MIB. He asks what is he like and she tells him that he's special.

He then asks if he can keep the game and she says of course and that she left it there for him. Presumably, this is a lie because she doesn't want him to know that there is a world beyond the island. She asks where else could it have come from, and he says from somewhere else, across the sea. Mother says that there is nowhere else and the island is all there is.

MIB asks where did they come from then, and Mother says that he and Jacob came from her and she came from her mother. He asks where her mother is and she says that her mother is dead. MIB asks what dead is and she tells him that it's something he'll never have to worry about.

So clearly, we see that Mother certainly has more in common with MIB than Jacob. She is manipulative and certainly knows how to lie, but is she truly crazy like Locke said earlier this season? I guess it's subjective.

Claudia gives birth to Jacob & the Man In Black, Mother kills her with a rock

At the caves, Mother sits with a mortar and pestle, grounding up something to help Claudia's wounds. Claudia is eating some food and asks where the rest of Mother's people are, and Mother says that it is just her. Claudia asks how she got to the island and other says the same way she did, by accident. Claudia starts to ask "How long have you..." and Mother interrupts her and says "Every question I answer will simply lead to another question."

Claudia says there were other people on her ship and Mother suddenly interrupts her and says if there are other people on the island, she will find them. Claudia then starts to wince in pain as the baby starts coming.

Some time passes and Mother is helping Claudia give birth to her baby. After struggling, the baby is born and Claudia says that his name is Jacob. Mother sits him on a blanket and looks at him happily. Then, Claudia starts struggling again and Mother looks concerned. She discovers that there is another baby that she is giving birth to. After the other baby is born, Claudia says she only picked one name, so the Man In Black still has no name.

Both babies are laying next to each other, Jacob wrapped in a white blanket and the Man In Black in a black blanket. Also, Jacob is calm and looking around, while the Man In Black in crying.

Claudia asks to see the babies, then Mother moves over her and says "I'm sorry." She then bludgeons Claudia to death with a rock. We hear the repeated blows as we look at the two babies.

So it seems that Fake Locke wasn't completely lying about when he told Kate that he had a crazy mother, and we see more of that later in the episode.

Jack & Hurley find Shannon's inhaler, visit the caves, Adam & Eve skeletons & Christian's coffin

As Jack and Hurley make their way through the jungle, Jack steps on something that was pivotal to the season one plot. It's none other than Shannon's missing inhaler.  Jack looks up and realizes that they are at the caves which were last seen in the season two episode "Adrift."

They go in the caves and Hurley examines the "Adam and Eve" skeletons, which had only been seen once before in the season one episode "House of the Rising Sun" when Jack discovers them. Hurley comes up with a theory that the survivors time travel to "dinosaur times" as he calls it, died and were then laid to rest in the caves.

Meanwhile, Jack is staring at Christian Shephard's coffin which he destroyed in the season one episode "White Rabbit" after he discovers Christian's body is not inside. He tells Hurley the truth about how he found the caves, since everyone originally thought he stumbled upon them while looking for water.

Hopefully this scene is going to lead to an answer to both of these big questions in coming episodes. Exactly who are the skeletons, how did they get there and when? And then, what exactly happened to Christian's body and is it somehow tied to the body's disappearance in the new timeline?
