Lucy Stillman

"Have faith, Desmond..."

- Lucy, showing to Desmond she is on his side.

Lucy Stillman is a genetic-memory researcher working for Abstergo. It is later revealed that she was secretly working as a spy for the Assassins in attempt to free Desmond from Abstergo's hold.

Early Life
Lucy Stillman was a research assistant for Dr. Warren Vidic. She had been working for Abstergo Industries for three years, focusing on the Animus project. Dr. Warren Vidic considered her as an invaluable asset for Abstergo for her intelligence and knowledge in cognitive neuro-science and values her highly, although he does not express it. She was a talented student at her university. She studied science but was rejected in many fields of work because of some of her beliefs in science that related, unbeknown to her, to the work Abstergo performed to achieve the information to retrieve their goals. She apparently tried everything to get a job and jokes to Desmond, "I was this close to waiting tables".

Understandably, she was excited when she got a call from Vidic offering her a job. She accepted and worked with Vidic for an amount of time. She was also apparently friendly with a few other employees at Abstergo, but it was these same people who tried to kill her before Vidic intervened.

As the game progresses, Desmond learns more and more about Lucy. He does this in two ways:

Conversations
Throughout the game, Desmond can speak to Lucy and get to know her better at the end of each memory segment, after Dr. Vidic leaves the lab. As Desmond talks to Lucy, she starts to tell him a bit about her past.

Lucy explains that during her university career she was ostracized for her scientific beliefs and theories. The criticism continued after university- no scientific organization or academic institute would employ her. Desperate, she was almost ready to give up science altogether. Then she received a call from Dr. Vidic, who told her he agreed with her theories and offered her the chance to work for Abstergo and to prove her theories to be true. The beliefs she was criticized for may have regarded genetic memory. Lucy is portrayed in the game to be knowledgeable about the Animus, so it's likely that, because of her feelings on genetic memory, Vidic contacted her so she could contribute to the creation of the Animus.

Lucy also reveals to Desmond that he is not the only person Abstergo is detaining- she too is a captive. She then tells him a story about how a while back, Abstergo decided to silence her to keep her from speaking about the Animus, but before her assailants could commit her murder, they were ordered to stop by Dr. Warren Vidic. She claims that he saved her life that day, and she tells Desmond not to judge Dr. Vidic so harshly, as he is under a lot of pressure.



Emails
At various points in the game you can gain access to Lucy's computer and read her emails. Desmond comes upon the codes to Lucy's emails when he finds door codes to the main room in his wardrobe, and Lucy's access pen, which was left on the Animus. It can be speculated that she planted them to give him a better idea of what was going on with Abstergo. However, this is not certain. The codes may have been left there by a previous subject, and the pen left by mistake.

From the messages, you definitely get the idea that she is telling the truth, as she is obviously concerned for her own safety and is trying to find out more information about a previous Abstergo employee who died a while back. This employee is said to have "committed suicide" but the documents relating to the death are being held as classified and are not being released.

In one deleted email, there is a conversation in which Lucy tells another person that she has been delaying the doctor from finding the artifacts and asking for the other person to send a rescue. A strange reply appears to be an attachment, but has random capitalization of letters. When these capitalized letters are put together, they form, "WE WILL BE THERE SOON". Towards the end of the game, a gunfight is heard outside, and Vidic explains that present-day Assassins have come for Desmond. The hidden message was probably a reference to the attack. If so, it would mean Lucy is an assassin, which is also shown by her showing Desmond her left hand and symbolically bending her ring finger (see photo), to have it appear like Altaïr's missing finger, and is spying on Abstergo Industries. The V-neck and collar of her blouse, if turned upside down, are also identical to the Assassin's logo. At the end of the game, Desmond gains the ability to use Eagle Vision. When Desmond uses this on Lucy, she appears with a blue aura, confirming her to be a trustful ally.

The achievement of "Conversationalist" can be unlocked in the 360 version of the game.



The Side Story of Leila and Neumann
It is stated in Lucy's e-mails that her friend Leila Marino died in September 2007 and that no circumstances were revealed to her. Vidic replied that it was suicide and that "it had something to do with a kid named Neumann." Lucy asked Nancy Nilop for information concerning Leila's death to which Nancy replied that the coroner's report was confidential. Lucy also sent an e-mail to Alan Rikkin to which he never responded.

Assassin's Creed II
Taking place a couple of hours after the end of the first game, Lucy is reintroduced to the story with blood splatters on her shirt, presumably from fighting her way to where Desmond is being held. Lucy flees with Desmond from the Abstergo building to the Hideout, where she introduces Desmond to two of her assassin friends, Shaun Hastings and Rebecca Crane, and also tells Desmond about what happened to Subject 16. During this time, Desmond can engage in conversations with Lucy, some of which hint toward a romantic involvement.

When Abstergo invades their hideout, she gives Desmond a Hidden Blade and they go to fight them. When she sees Vidic, he reminds her that he saved her, which is why she came to work for Abstergo. When the Abstergo guards are defeated, Lucy and the others' escape the hideout, and head to another one in the mountains, while Desmond is preparing to enter the Animus again to continue searching for clues, while she studies the notes and tries to figure out what the "god" Minerva meant, and also tells Desmond that everything she feared would happen, is starting to happen.



Personality
In contrast with Warren Vidic's personality, Lucy is an optimistic and cheerful woman with a bright personality. She always has some encouraging words and sympathy towards Desmond Miles, though it obviously irritates him sometimes. At times when Warren Vidic attempts to force Desmond to go deeper to the Animus memory, Lucy will stop him from going and plead with Vidic to let Desmond to rest, showing her caring personality however she may also be doing this to slow down Vidic and Abstergo from getting the Piece of Eden.
