Cyril Mitchell is the person that Rafe's mother had given him to contact as a last result. Maya Delaney, Daniel Bianchi, and Corey Carling attempt to get a hold of Cyril in The Rising but find out that he died six months before the call was made when his daughter, Sylvia, answers the phone instead. He died of a heart attack but Sylvia believes it was because he was working for the St. Clouds.
He found Ashton Gray when Ash went searching for answers online and offered him a place to stay but Ash refused. Instead, Cyril tried to give him money but all Ash would accept was information on the experiments.
Cyril used to work for the Edison Group.
