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.

Richard Alpert returns, checks out baby Locke

Here, we see Emily Locke, her mother and the nurse standing next to baby John Locke. The nurse tells them that he is being referred to by the other nurses as the "miracle baby" due to his being the youngest premature baby to survive at the hospital. He also had infections and pneumonia and fought them off. Before she can hold John, Emily runs out of the room saying, "I can't do this." Emily's mother asks about adoption as she starts to light a cigarette before being told by the nurse that she can't smoke there.

Then comes the best part of the scene. Richard Alpert returns for the first time since season 3 (Cane was good but I'm glad it's gone so Nestor Carbonell could return to Lost). He appears at the window looking in on baby Locke. The nurse asks Emily's mother if he's the father and she says she's doesn't know who he is. Again, Richard Alpert appears to be the same age as every other appearance, even though it's the 1950s this time.

Why was Alpert watching Locke and how did he seem to know that Locke was special from his birth?

Emily Locke as a teenager hit by car

Here we see Emily Locke as a teenager as well as her mother, John Locke's grandmother. She is in her room listening to the Buddy Holly song "Everyday" when her mom comes in and asks her if she is going out with "him." I assume him means Anthony Cooper (or whatever is real name is). She runs out into the street in the rain and gets hit by a car.

Lostpedia has the date of John's birth listed as May 30, 1956, but the Buddy Holly song "Everyday" wasn't released as a b-side to "Peggy Sue" until 1957. Was the song placement a mistake or is John's date-of-birth wrong?

Also, who was driving the car that hit Emily? Was is similar to the experience Anthony Copper claims to have had when he was brought to the island?
