Lucy Stillman

Trained by the Brotherhood from childhood and planted inside Abstergo's Animus program, Lucy spent years as Vidic's assistant, protecting subjects where she could — she talked the Templars out of ending Desmond after his usefulness lapsed, then broke him out entirely. In the warehouse and Monteriggioni days she was the cell's leader and Desmond's anchor. The ugly question underneath — revealed only after — is when the years undercover stopped being cover: cut off, unacknowledged, and courted by Vidic's cause, Lucy had quietly agreed to deliver the Apple to Abstergo.
