Lucy Stillman

"Desmond, shut the fuck up...please."

- Lucy and Desmond escaping Abstergo

Lucy Stillman (born 1988) is a member of the Assassin Order and former genetic memory researcher, working for Abstergo Industries on the Animus project. During her time at Abstergo, she spied on the company and helped Desmond Miles escape the Abstergo Laboratory. She then aided in Desmond's training to be an Assassin, alongside Shaun Hastings and Rebecca Crane.

Early life
Before starting work with Abstergo Industries, Lucy Stillman attended a university to study cognitive neuroscience, but was forced to leave when her mentors began to hold issue with her topic of study (considered pseudoscience). Forced out of the university, she applied at a variety of locations and tried close to everything to achieve employment, at one point joking to Desmond, "I was this close to waiting tables."

Eventually, she was contacted by Dr. Warren Vidic, offering her a position at Abstergo Industries. She accepted the offer, and began working with Dr. Vidic on his Animus project immediately. For the first three years, Lucy was largely responsible for the design of a number of the Animus's functions and interfaces. While Lucy was on fairly cordial and friendly terms with a few other employees at Abstergo, such as Richard, these same individuals were later ordered to have Lucy killed, before Vidic intervened, seeing her as a valuable employee.

Working for Abstergo
Lucy was first seen after she pulled Desmond out of the Animus, seeing that his subconscious would not let him view the specific memory that Abstergo wanted. As Warren explained to Desmond what the Animus does and what genetic memories are, she explained Abstergo's goal without revealing too much information to Desmond.

In between sessions, Lucy asked Desmond questions concerning his past, or answered Desmond's questions with what little she could reveal about Abstergo's goals. Lucy also mentions that he was not the only person Abstergo was detaining, and that she too was an unfortunate captive. She then told him a story of how, in the past, Abstergo had decided to silence her, to keep her from speaking about the Animus; but before her assailants could commit her murder, they were ordered to stand down by Dr. Warren Vidic. She claimed that he had saved her life that day, and she told Desmond not to judge Dr. Vidic so harshly, as he was under a lot of pressure.

As more time passed on, Lucy leaves the access codes behind in Desmond's wardrobe, so that he could finally leave his room. On top of the Animus, Desmond found Lucy's pen, which was also left there for him to find. This gave him access to her computer, in order to read her e-mails. Later, Lucy revealed to Desmond that she to is also an Assassin and was only undercover to learn more about Abstergo's plans.

When Desmond finished his time in the Animus, reliving the memories of Altaïr Ibn-La'Ahad, three Abstergo CEO's, along with Warren, decided to kill Desmond, seeing as they had already retrieved the information they needed. Lucy intervened, and convinced them to keep Desmond for more testing, as his memories could still reveal more about the locations of the Pieces of Eden. In turn, she had to leave him behind in the lab.

Escape to the Hideout
A few hours after Lucy and Vidic left, Desmond was still trapped in the lab after he had first used his new skill, Eagle Vision. Suddenly, Lucy rushed inside with blood splatters on her shirt from fighting her way through the Abstergo facility. Lucy told Desmond that there was no time to waste, and that he had to get into the Animus to retrieve the memory core data. Lucy wrote the data on a disk and decided it was time to flee. The two successfully fought their way down the facility, and made it to the parking lot. There, they found themselves confronted by guards. Quickly disposing of them, Lucy told Desmond to go into the trunk of a car "for [his] own protection". When the ride was over, the pair arrived in the Hideout. Before entering the main room, Lucy told Desmond that she had brought him to the Hideout to train to be an Assassin, by using the Animus 2.0 and its bleeding effect to imprint skills through Ezio Auditore da Firenze. Entering the Animus 2.0 room, Lucy's fellow Assassins, Shaun Hastings and Rebecca Crane, introduced themselves to Desmond, and set preparations for the sessions. Later in the day, Lucy evaluated Desmond's progress in between the sessions. The night after, Lucy and Desmond talked once more, where Desmond promised that he would protect her.

After Desmond made his new discovery through Ezio from the the Vault in Rome, the alarm went off as Abstergo invaded their hideout. In a rush, Lucy gave Desmond a Hidden Blade similar to Ezio's, and made her way downstairs. When Lucy encountered Warren Vidic again in the warehouse, he reminded her that he had saved her, which was why she came to work for Abstergo in the first place. Vidic burst out in anger as he stated his disappointment in her for her "betrayal". Both Lucy and Desmond engaged in a fight with the Abstergo guards, and managed to defeat them. Vidic was last seen in the back of a truck, stating that the attack was only the beginning, and fled. When Desmond started to go after him, Lucy stoped him and said that they will bring Vidic to justice for what he has done eventually. Lucy and the others evacuated the hideout, despite having defeated the guards from Abstergo, as their location had been revealed, and Abstergo would most likely be back with reinforcements. They left to hide out in the mountains, while Desmond was preparing to enter the Animus again to continue their search for clues. Meanwhile, Lucy continued to study the session notes to try to figure out what the "Goddess" Minerva meant and also told Desmond that everything she feared is starting to happen.

After a long drive, the Assassins finally arrived in Monteriggioni, setting up a new hideout in the Sanctuary underneath the Villa Auditore. She and Desmond access the sanctuary together via underground sewers and tunnels.

After reliving Ezio's last memories in the Animus, the Assassins discover that the Apple of Eden was hidden by Ezio in a vault underneath The Colosseum. After retrieving the Apple, Juno takes contol of Desmond's body saying "A sacrifice must be made to awaken her". Juno then proceeds to force Desmond to kill Lucy. It is unknown at this time wheither Lucy will survive, however, when she and Desmond passed out the Apple fell in-between them, with Desmond unconcious the player is returned to play as Ezio in "free roam".

Personality
In contrast with Warren Vidic's personality, Lucy is a warm and patient woman with a bright personality. She always lends 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 allow Desmond to rest, showing her caring personality.

During Assassin's Creed II, it is shown that she is cunning and resourceful for keeping Desmond's night-time explorations of the Animus room secret, but becomes irate or worried under too much pressure. She becomes sensitive to the death of her collegues like her friend Leila Marino, her role to Subject 16's loss of sanity, and the stress over the death of two more (eight Assassins) teams in the field.

Trivia

 * She is modeled after and voiced by Kristen Bell.
 * The achievement of "Conversationalist" can be unlocked in the 360 version of the first game by talking to Lucy every time Desmond comes out of the Animus. Note that you must talk to her completely, until she says that she's too busy to talk, or asks if he's tired.
 * Lucy's character model is drastically altered between games. In the first Assassin's Creed, she is dressed in appropriate business/work attire. In Assassin's Creed II, her clothes are much more casual, and she has a slightly more curvaceous figure, and different facial structure: larger eyes and lipstick. Lucy's eyes also go from blue-grey to completely blue. In Assassin's Creed: Brotherhood, she wears a brown jacket over her clothes from Assassin's Creed II.
 * In Assassin's Creed II, it is revealed that she is a very successful fighter, taking down many Abstergo guards while she and Desmond were escaping the Hideout.
 * It's implied throughout Assassin's Creed II that Lucy and Desmond have feelings for each other. There is evidence of this by her caring for his well-being due to the Bleeding Effect, as well as hugging him and saying that she's glad he's with the Assassins before Desmond's training. It is also implied through Desmond by example of him trying to be humorous around her and always asking how she is and trying to make her feel better about Subject 16, saying that its not her fault about what happened to him. Desmond has also said that he would protect her, further implying feelings between them.
 * In Assassins Creed: Brotherhood it is revealed that Lucy has free-running abilities like Desmond and his ancestors.
 * In Assassin's Creed: Brotherhood, she seems to have a scene from Project Legacy on her computer in the sanctuary.
