Carter (The Hand of Fear)
From Tardis Wiki, the free Doctor Who reference
Dr. Carter was a pathologist in the hospital at which the Fourth Doctor and Sarah Jane found themselves following an accident at a quarry. The Doctor tasked him with investigating the stone hand that Sarah had found in the quarry.
While doing so, he was attacked by Sarah Jane, who had come under the influence of Eldrad. Thereafter, he joined the Doctor's effort to track down Sarah, giving the Doctor a ride to a nearby nuclear power station.
