Jule (previously named Victoria) is a female synth living in Acadia in 2287. At an unknown point, Victoria escaped from the Institute and found her way to Far Harbor, and then to Acadia. She was a friend to the residents there, until she was swayed to go on a boat ride with Faraday. She felt very nervous about the ride, but was apparently comforted by Faraday's looks.
The boat crashed, with Victoria receiving severe damage to her head, resulting in Faraday having to mind-wipe her in order for her brain to function properly. But there was an issue with the mind wipe, resulting in Jule now mentally damaged, jumping between two distinct personalities in her speech, and having severe issues with her memories. By the time the Sole Survivor arrives, she is very moody and sarcastically angry. She refuses to speak to the player until the quest Data Recovery. She apparently suffers from nightmares about the crash, and only confides in Cog.
