Rebecca Crane is the Assassin technician who works beside Shaun Hastings in Assassin's Creed Syndicate's modern-day scenes. She helps recover the Frye twins' genetic data from Isabelle Ardant's London office and joins the final attempt to take the Shroud of Eden from the Templars.
Rebecca and Shaun infiltrate Ardant's office, retrieve the twins' data for Bishop and bug the room. Their decision to wait and kill Ardant nearly ends with Sigma Team executing them before planted explosives let them flee. Later she sleeps while Shaun keeps watch, just before Galina arrives.
In the fight beneath Buckingham Palace Rebecca first tackles Violet da Costa to stop her shooting Galina, then takes a bullet for Shaun. She survives, and Eric Cooper later extracts her and Shaun from London.
