T.E.S.S. What does this stand for? Test Electro Surrogate Synhuman. She was supposed to be a revolution in technology and science and more importantly save Matt's eight year old daughter from the cancer but the project failed. Something went wrong during the consciousness transfer and it happened. The virus, anomaly, trojan, glitch in the system, whatever you want to call it. It Drives T.E.S.S. insane. When it attacks, she kicks and screams wanting it all to end murmuring 'it won't leave it won't leave' over and over again. In her spare time she talks to Ash, her security system. Why doesn't Matt find a way to end his daughters misery you ask? He's too afraid to lose her.
