Lincoln Six Echo

Lincoln Six Echo is the primary protagonist of The Island and Tom Lincoln's agnate.

History
Lincoln Six Echo was born around 2016, three years before the events of July 2019, and was intended to be an insurance policy for Tom Lincoln, who had contracted cirrhotic hepatitis and was facing liver failure.

Like all agnates, Lincoln Six Echo received memory imprints before entering the active population.

During his time at the Institute, Lincoln befriended Jordan Two Delta, Gandu Three Echo, and Jones Three Echo.

Lincoln’s Nightmares
Lincoln’s nightmares were a garbled combination of false, imprinted memories, the memories of his sponsor Tom Lincoln, what appear to be real memories of his birth, and his own fears. Throughout, he experiences the sensation of drowning, which wakes him up.

False and imprinted memories featured in the nightmares include subliminal messaging, both audio and visual. Text flashes on the screen, showing the words, “lucky”, “happy”, and “obedient”, while the face of Dr Merrick repeats the phrases, “You’re special... You have a very special purpose in life... You’ve been chosen... The Island awaits you.” Also seen is an eighth birthday party, the face of a child, and a baby crying, presumably depicting his fabricated childhood. Brief imagery depicting the Contamination is shown – warning symbols and people in hazard suits, as well as a bodybag being zipped up. Everything is interspersed with footage of the Island.

Several flashes show Tom Lincoln driving a car and a motorbike, which are presumably from memories that Lincoln is developing originating from his sponsor. Visions of the Renovatio also originate from Tom Lincoln, who designed and built it, but it is Lincoln and Jordan on the boat and Jordan is wearing white clothes that never appear elsewhere in The Island. Noticeably, they are both wearing their barcoded wristbands. In the first nightmare shown, Lincoln falls from the boat and Jordan ends up in the water with him.

The nightmares center around drowning and being manhandled by anonymous figures. It is suggested that this stems from memories of product extraction, as he is seen trapped within a gel sac as a technician shouts at him to breathe.

Lincoln’s nightmares started shortly before the 19th of July and it is unknown if they continued after his escape the next day, but as none are depicted it is assumed that they did not.

Personality
Lincoln's most exceptional trait within the Institute is his curiosity and questioning, something that Dr Merrick could not account for and discouraged. Jordan claimed that "...you always question the good. You only think about the bad." Ultimately, Lincoln's suspicions that something was wrong were proven correct. His questions didn't stop once he got outside, but his blind trust in his sponsor suggests that he shares the other agnates' optimistic naivity despite his cynicism (as opposed to pessimism).

Throughout the events of July 2019, Lincoln is motivated by a righteousness that pushes for the truth of Merrick Biotech to be revealed to the sponsors and the world, which, by his optimistic reasoning, would stop the agnate program and save his friends. He values this goal above his own safety, willingly returning to the Institute even after Tom Lincoln had been killed and the hunt called off.

Despite this apparent morality and valuing of human life, Lincoln is far less concerned than Jordan about their kill count. During the events of the film, he kills several people indirectly and at least one directly, expressing regret for exactly none of them.
