Jacob (Lost)

Jacob is a fictional character of the ABC television series Lost played by Mark Pellegrino. He is seen as the mysterious and ageless protector of The Island. He was first mentioned as the true leader of The Others by Ben Linus and was described as a "great man" that was also "brilliant", "powerful", and "unforgiving". He made his first appearance in the Season 5 finale "The Incident". He was also killed in this episode, but continued to appear as a ghost as well as in flashbacks in the episodes Ab Aeterno and Across the Sea. Being the unseen character for much of the series, almost all the events that take place starting from the plane crash right to the end revolve around him and his nemesis The Man In Black. In some of his appearances, Jacob has exhibited supernatural powers such as healing, near omniscience, conferring immortality, and changing peoples' destiny to suit his goals. Through these powers, he had a heavy influence on the lives of several of the main characters including Jack Shephard, Kate Austen, John Locke, James Sawyer, and Hugo Reyes.

Early life on the Island
Jacob's mother, a Roman woman named Claudia, was shipwrecked on the Island sometime in the 5th century. She gave birth to Jacob and The Man In Black. She was then murdered by the female protector of the Island who then raised the brothers. Jacob was clothed in light cloth, a trademark of his that continued into adulthood. They were told that there was no life outside the island and that it was just them. They were also told about a mysterious light that eventually one of them had to protect. Eventually, the Man In Black discovered that their 'mother' had lied to him and told Jacob, that she was not their mother, but they belonged to a group of people who had arrived on the island with their biological mother. Jacob loved his mother too much, and did not want to believe this. He ended up staying with his mother for the next 30 years, while The Man In Black lived with his people. The Man In Black and his people were about to discover how to tap into the light (which is revealed to be a source of electromagnetism) as a means of escaping the island. Their mother later initiated Jacob into becoming her replacement and proclaiming afterwards "that they're now the same". Unfortunately, the mother killed all of his people and in a fit of rage he killed her. Jacob, in return through vengeance, threw the Man In Black into the light, which he was told by his mother would lead to a fate worse than death. The Man In Black was now trapped on the Island and unable to escape until he killed Jacob. However, Jacob and the Man in Black are not able to kill each other due to the machinations of their mother. He attempted to manipulate other people who came to the Island into killing Jacob. Aside from making sure the Man in Black stayed on the Island, Jacob brings people to the island to further a philosophical debate that humanity is innately good while the Man in Black echoed their mother's belief that humanity is inherently corrupt. For several centuries, their debate has raged on with numerous casualties, thus being the many people Jacob brings to the Island and the Man in Black usually killing most of them to protect the island as a "security system".

The Others
In 1867, Richard Alpert was shipwrecked on the island. The Man In Black manipulated him into attempting to kill Jacob, however Jacob convinced him to join him. He then granted Richard immortality, told him the true nature of the island, and made him his spokesperson. Whenever people crashed on the Island, Richard convinced them to come under Jacob's wing, thus creating the island natives dubbed "The Others". Richard was the leader at first, however it was eventually moved on to others like Charles Widmore, Eloise Hawking and eventually Ben Linus. The leader of the Others would converse with Jacob and pass on his orders to the rest of the Others (who were not allowed to see him). However, when Ben became the leader, Jacob refused to show himself to Ben and Ben had to get the orders from Richard, sparking a slight resentment Ben had regarding his importance. Over time, Jacob had Alpert recruit people from the mainland to become part of his group such as in the case of Juliet Burke.

The Candidates
Jacob feared that The Man In Black would eventually kill him, so he chose candidates, who would succeed him after his death. He recruited people who he knew had lost hope in life. He recruited Kate and Sawyer when they were children. Specifically, he protected Kate when she was caught stealing and touched her. He then made contact with a young Sawyer when he was writing a threatening note to Anthony Cooper. He visited Sayid Jarrah around this time and this leads to the death of Sayid's wife. He touched him as consolation. He later visited Sun-Hwa Kwon and Jin-Soo Kwon at their wedding and touched them to give his blessing. He also touched Locke when Locke apparently died after being pushed off a very high building. He then touched Jack after Jack was taught about the counting to five strategy from his father. Hurley was touched by him right before boarding Ajira Flight 316. He managed to make all the candidates attend the Oceanic Flight 815 so they could crash on The Island and succeed him.

Death
The Man In Black finally found a loophole in Ben Linus. He convinced Ben that Jacob had neglected him and that he must kill Jacob. Jacob awaited his doom in a statue of Tawaret where he lived. As Ben came in, he made a final attempt to convince Ben not to do it. However, Ben stabbed Jacob several times and then The Man in Black kicked him into the fire. Jacob then returned as a ghost and guided Hurley and the rest of the survivors as to how to defeat the Man In Black. At some point in the past, Jacob compiled a list of 364 candidates (virtually everyone that has visited the island since at least 1988) on a glass dial in a derelict lighthouse that only he is aware of until he instructs Hurley to take Jack there in an successful effort to show how important the latter is to his plan. Jacob constructed the list in a way that could correspond to certain numbers, just as he did in a cave that had more recent revisions. The Man in Black later showed Sawyer this cave in his elaborate plan to kill the candidates. It is later revealed that the candidates can't be killed by the Man in Black due to Jacob's rules so the former improvised his plot by manipulating the candidates into killing themselves which became partly successful with the deaths of Jin, Sun, and Sayid. His spirit finally vanished after he made Jack succeed him.

Development
The producers, particularly Damon Lindelof and Carlton Cuse, have stated that the character was inspired by Aslan from the Chronicles of Narnia, exemplifying his god-like powers and kind nature. Much like Aslan, Jacob serves as an almost eternal guardian of a fantastical realm, in this case, being the Island instead of Narnia. Lindelof also stated that he and co-creator J.J. Abrams had planned for the concept of light and dark to eventually be personified by Jacob and Man in Black, referencing the scene in Pilot, Part 2 where Locke explains the game of backgammon to Walt Lloyd. . In addition, Christ can be seen as the prototypical model for the character of Jacob which was also the case for Aslan. In the episode, "What They Died For", Jacob appears before a burning bush and Jack accepts his responsibilities, mirroring Moses from the Book of Exodus. Another similarity can be attributed to Zoroastrianism where Jacob can be seen as Ahura Mazda and the Man in Black is that of Angra Mainyu ("the Angry Man"). Curiously enough, that phrase is used by Jacob's assistant, Dogen, who explains the nature of the Man in Black to Sayid.
