Sunny Bennett is the granddaughter of Walter Bennett.
Sunny is the granddaughter to Walter Bennett. She was present in her grandfather's lab along with Simon Simms when Walter was working on his teleporter. However the lab ended up being raided by Walter's brother Moral Bennett and agents working for the Clandestine Company. Walter was shot dead, and Sunny and Simon were taken away by agents.
Although Nathan managed to negotiate the release of Simon, the Clandestine Company refused to give up Sunny. She was later transferred to an unknown location in order to receive experimentation and brainwashing.
