Driscoll (The Hand of Fear)

Driscoll was an employee at the Nuton Power Complex. He was part of an armed radiation team sent to get Sarah Jane Smith out of the fusion room. When he and his team couldn’t get through the doors, the Doctor found a way in through the cooling duct. After Sarah was removed from the fusion room, Driscoll went back in to remove Eldrad's hand for examination and containment. The Doctor noticed that Eldrad's ring was missing and Sarah, barely able to remember anything, didn’t know anything about it either. Driscoll volunteered to go back in and search for it. When he did he too was taken over by the ring's influence. Asking him if he found anything he said he found nothing. In decontamination, he knocked a man unconscious and took Eldrad's hand and headed for the reactor core. When the Doctor realized that he must have been taking over, he set out in pursuit of him and told others to stop him as well. They were unsuccessful as Driscoll used the power of the ring to blast down the guards sent after him. Entering the fusion room, Driscoll unlocked the door to the reactor core and went in taking the hand with him. He was no doubt vaporized -sacrificed for the sake of Eldrad's regeneration.
