Lucy Stillman

"No, no, you're right. Let's all just screw around while the world falls to pieces."

- Lucy to Desmond in the Sanctuary

Lucy Stillman (born 1988) is a member of the Assassin Order and former genetic memory researcher for Abstergo Industries' Animus project. During her infiltration of Abstergo, she reported back information to the Assassins on their recent activities. Once Desmond Miles had finished reliving his ancestor Altaïr Ibn-La'Ahad's memories, Lucy helped him to escape the Abstergo laboratory. She then took him to the hideout, where he began his Assassin training, with the aid of new allies, Shaun Hastings and Rebecca Crane.

Early life
Before starting work with Abstergo Industries, Lucy Stillman attended 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 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, who offered 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' 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 Vidic 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, and answered his about Abstergo, while trying not to reveal too much information. Lucy also stated 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, in order to keep her from speaking about the Animus; but before her assailants could eliminate her, they were ordered to stand down by Warren Vidic. She claimed that he had saved her life that day, and told Desmond not to judge Dr. Vidic so harshly, as he was under a lot of pressure.

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

When Desmond finished his time in the Animus, three Abstergo executives, along with Vidic, decided to kill Desmond, seeing as they had retrieved the information they needed. Lucy however 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.

Escape to the Hideout
A few hours after Lucy and Vidic left, Desmond was still trapped in the lab, after he had used his new skill, Eagle Vision, to view Subject 16's hidden messages. Suddenly, Lucy rushed into the room, with stains of blood 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, along with Desmond, began to flee. The two successfully fought their way out of the facility, and eventually made it to the parking lot.

There, they found themselves confronted by more guards. Quickly disposing of them, Lucy told Desmond to go into the trunk of a car "for [his] own protection." When the drive was over, the pair arrived at the hideout. Before they entered the main room, Lucy told Desmond that she had brought him to the hideout to train him to become an Assassin, by using the Animus 2.0 and its bleeding effect to imprint skills through another ancestor, Ezio Auditore da Firenze. Entering the main room, Lucy's fellow Assassins, Shaun Hastings and Rebecca Crane, introduced themselves to Desmond, and began preparations for the sessions. Later in the day, Lucy evaluated Desmond's progress, by tasking him with setting up the security systems. In between sessions, they also spoke of issues such as the Templars, and other Assassins.

After Desmond discovered the Vault in Rome by reliving Ezio's memories, the alarm went off as Abstergo invaded their hideout. In a rush, Lucy gave Desmond a Hidden Blade similar to Ezio's, and they made their way downstairs. When Lucy encountered Warren Vidic in the warehouse, he reminded her that he had saved her life. Vidic burst out in anger as he stated his disappointment in her because of her "betrayal". Both Lucy and Desmond engaged in a fight with the Abstergo guards, quickly defeating them. Vidic was last seen in the back of a truck, stating that the attack was only the beginning, and then fled. When Desmond started to go after him, Lucy stopped him and said that they will bring Vidic to justice for what he has done eventually. Lucy and the others evacuated the hideout, as their location had been revealed, and Abstergo would be back with reinforcements. They left in a van to hide in the mountains, and Desmond prepared 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 had meant, telling Desmond that everything she had feared was starting to happen.

Search for the Apple
After a long drive, the Assassins finally arrived in modern-day Monteriggioni, setting up a new hideout in the Sanctuary underneath the Villa Auditore. She and Desmond both opened the door to the Sanctuary by passing through the underground sewers and tunnels.

After Desmond relived Ezio's last memories, the Assassins discovered that Ezio had hidden the Apple of Eden in a vault underneath the Colosseum. After Desmond retrieved the Apple within the vault, Juno took control of Desmond's body and said that "The Path must be opened. The scales shall be balanced." Desmond was then forced to stab Lucy in the abdomen with his hidden blade.

Her fate remains unknown.

Personality
"Let me guess, you're more the in-bed-at-six type."

- Desmond to Lucy while they travel to the Sanctuary.

In contrast to Warren Vidic's personality, Lucy is a warm and appreciative individual with a bright personality. She always lends encouraging words and sympathy towards Desmond, though it irritates him sometimes. At times, when Warren Vidic attempts to force Desmond to go deeper into the Animus memory, Lucy will stop him from doing so, and plead with Vidic to allow Desmond to rest, showing her caring personality.

Lucy is also both cunning and resourceful, 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 colleagues, particularly her friend Leila Marino, as well as her role in Subject 16's loss of sanity, and the stress over the death of two more teams (eight Assassins) in the field.

Trivia

 * Lucy is modeled after and voiced by Kristen Bell.
 * The name "Lucy" means "Light." Whether or not this is meant to reflect her character is unknown.
 * The achievement "Conversationalist" can be unlocked in the Xbox 360 version of Assassin's Creed by talking to Lucy every time Desmond exits the Animus. Note that Desmond must talk to her completely, until she says that she's too busy to talk, or asks if he's tired.
 * In Assassin's Creed II, Lucy drives a car similar to the real world Mercedes CLS.
 * Lucy's character model is drastically altered between games. In the first Assassin's Creed, she is dressed in appropriate business attire. In Assassin's Creed II, her clothes are much more casual, and she has a slightly more curvaceous figure, and different facial structure and hairstyle, with larger eyes and lipstick. Lucy's eyes also go from blue-gray to completely blue. In Assassin's Creed: Brotherhood, her model is again altered, looking closer to the first game's version, with a brown jacket worn 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 Abstergo, and later, the Hideout. In Assassin's Creed: Brotherhood, she is seen to have a similar level of free-running abilities to Desmond and his ancestors.
 * It is implied throughout Assassin's Creed II and Assassin's Creed: Brotherhood 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.
 * In Assassin's Creed: Brotherhood, an e-mail she received from William M. also further implies that Lucy has feelings for Desmond. The message states that she should not keep Desmond out of danger "just because of feelings she may or may not have" for him.
 * In Assassin's Creed: Brotherhood, Lucy has Assassin's Creed: Project Legacy up on her computer in the sanctuary, set to the memory sequence for Mario Auditore.
 * Lucy's e-mail password in Assassin's Creed: Brotherhood is "Juno57". This proves to be foreshadowing, as Juno is the one who controls Desmond when he stabs Lucy.
 * While Desmond talks to Lucy outside the Villa in Assassin's Creed: Brotherhood, she comments that nearly a decade of her life has been spent searching for the Pieces of Eden. That would mean she had been looking for the Pieces since she was at least 14 years old (according to her birth year).
