Gemma Griffin

Gemma Griffin was a human who lived in the town of Folkestone. She was the daughter of Harriet Griffin. She and her brother Samson met with the Eighth Doctor in a library and had several adventures with him.

Travels with the Doctor
After meeting the Doctor in the Folkestone Library where Samson worked, he and Gemma followed the Doctor into his TARDIS. The Doctor and the two siblings travelled to several planets, including Valuensis, Porteus and Murgatroyd. They visited the Ice Caves of Shabadabadon, the court of Queen Elizabeth I, prehistoric Earth and Studio 54. (AUDIO: Terror Firma)

The Doctor once left Gemma and Samson in Vienna in 1816 while he went to investigate a distress call. (AUDIO: Mary's Story) Having recently acquired the 19th century British author Mary Shelley as a companion, he had intended to retrieve Samson and Gemma and continue their travels. However, he and Mary arrived in Vienna on 11 September 1873, fifty-seven years later than intended. (AUDIO: The Silver Turk)

They also paid a visit to a friend of the Doctor's, Edward Grainger, on 25 June 1956. (PROSE: Dear John)

Encounter with Davros
After a trip to Valuensis, the trio came across a Nekkistani time cruiser. The siblings went on board to explore, and met Davros. He took control of their minds, and forced Samson to knock out the Doctor. Davros used his control of Samson to control the TARDIS, piloting it back to Earth. Davros then altered the Doctor's memory so he forgot all about the two siblings.

The Doctor went on his way. He eventually met Charley Pollard and C'rizz. Samson remained subconsciously aware of the Doctor's travels. Davros used this to monitor the Doctor. Davros had infected Gemma with a disease which mutated humans into Daleks. He used this to pave the way for the Dalek invasion of Earth.

The Doctor, Charley and C'rizz arrived on Earth and Davros sprang his trap. C'rizz joined a small unit of Daleks headed by Gemma. They attempted to make him the new Dalek emperor. This attempt failed. In the end, the Doctor blackmailed the Daleks into leaving Earth, taking Davros with them and releasing Samson and C'rizz, whom they had captured, from their control, though not before Gemma had been killed.
