Tom Watson
Tom Watson was a fish stabber. He and Trevor injected antibiotic serum into fish from the lake.
One day at work, Tom accidentally injected himself with the serum. The next day he felt so good that he put some in his tea. He started to hear voices — the fish were asking him to stop injecting them. The Sixth Doctor and Peri arrived and offered to help him.
He brought Peri home to dinner and introduced her to his wife Mary and his daughter Linda. At dinner he talked about his vegetarianism.
The next morning at work, he made his farewells to the Doctor and Peri. He drank his tea, not knowing that Peri had put something in it. His headache cleared and he stopped hearing the voices. (PROSE: The Stabber)
