George Harrison (Slow Decay)

George Harrison, most often simply called George and named after the Beatles member of the same name, was the name which Jack Harkness gave to an alien tapeworm which infected Rhys Williams.

Rhys was infected with George when he took a 'Start' pill given to him by Dr Scotus in order to try and both lose weight and save his marriage. Growing inside him, George forced him to gorge himself on food, while Rhys lost weight at the same time.

Gwen Cooper advised Rhys to swallow the 'Stop' pill given to him by the Scotus Clinic. She didn't tell him about the creature living inside him. He swallowed the pill, flushing George from his body using the nearest toilet. (PROSE: Slow Decay)
