The foster mother of Jacob and his brother murdered their birth mother Claudia just after the twins were born, and raised the twins herself. She was the protector of the Source until shortly before her murder by Jacob's brother.

According to the Man in Black, she was "crazy" and responsible for his growing pains as a child ("a long time ago") that continue to this day. Template:Crossref

On the Island

Her presence on the island pre-dated any other individual known. Approximately 2000 years ago, she found Claudia, heavily pregnant and shipwrecked on the Island. When Claudia asked her how she had arrived on the island, Mother replied "the same way you did; by accident." When asked how long she had been there, Mother cut her off and flatly stated "every question you ask will only lead to more questions." Moments later, Claudia went through labor, with Mother assisting her in the delivery. After Claudia had given birth to Jacob and his twin brother, Mother killed Claudia. Eventually, she would tell Jacob that she had done this because Claudia and the other people who were shipwrecked with her were bad people, and she did not want the infants to be raised by them and therefore become "bad".

Jacob and the Man in Black grew up believing this woman was their mother. She told them no where other than the Island existed, and that her mother had died. She also said that she had "made it" so that Jacob and the Man in Black would not be able to hurt (or, kill) each other. When Jacob and the Man in Black were thirteen, she took them to a cave filled with water and light. She told them it was "the heart of the island", and that she was its protector; she also said that someday one of them would have to take her place as the protector of the light.

After the Man in Black learned from Claudia's ghost the woman had lied to him, he decided to leave her and live among Claudia's people. Jacob decided to stay with the woman, but continued to visit his brother. After several decades, the Man in Black and Claudia's people learned about the magnetic energy pockets on the island, and dug wells to learn more about them. In a chamber beneath one of these wells, the Man in Black had started to build a wheel which he hoped to use to leave the island. When the woman learned about his plans, she confronted him and knocked him out. When he regained consciousness, he found the well had been filled in and all Claudia's people were killed.

Meanwhile, the woman took Jacob to the cave of light, and gave him a cup to drink. She said by doing so, he would take on the responsibility of protecting this place for as long as he can, after which he will have to find his replacement. However, she told him never to enter the cave, and if he did, it would be "worse than dying". With reservations (which arose because he believed the woman favored his brother), Jacob accepted the cup and the responsibility.

The woman returned to the cave where she lived and her belongings and loom were destroyed. As she examined the black playing piece from the Senet game, the Man in Black stabbed her from behind with his dagger. As she died, she said, "Thank you." Template:Crossref


After Jacob fought with the Man in Black and threw him into the cave of light (thus transforming him into the smoke monster), he took the woman's body and the Man in Black's body and laid them to rest in the cave, with a pouch containing one black and one white stone from his brother's Senet game.

Their skeletons were discovered millenia later by Jack Shephard and Kate Austen; John Locke subsequently nicknamed them "Adam and Eve". Template:Crossref

When telling Kate about Aaron now having a crazy mother, the Man in Black described his own mother as "very disturbed" and responsible for him having issues that he was still trying to work through. Template:Crossref

  • Her nickname on's LOST Untangled was "Knotty Mommy Hair", similar to Claires's nickname on the show "Crazy Jungle Hair Claire".
  • While Damon Lindelof and Carlton Cuse have not confirmed nor denied the theory that Mother was the Monster prior to the Man in Black, they did note that while [she is] "a scrapper", for her do wipe out the Man in Black's village as a human by herself against "twenty armed men" would have been "impressive, especially in daylight".
