She is heard again in "Project: Nirvana" and "Black and White" and "Gods and Monsters", all alongside another new military companion, Captain Aristedes. Sally is voiced by Amy Pemberton. A companion of the Eighth Doctor mentioned in "The Gallifrey Chronicles" by Lance Parkin and possibly taken from the Telos novella "Rip Tide" by Louise Cooper. Alice Obiefune was a companion of the Eleventh Doctor in Titan's Eleventh Doctor series. Molly O'Sullivan (played by Ruth Bradley) is an Irish Voluntary Aid Detachment nursing assistant in World War I and companion of the Eighth Doctor. The character first appears in "Dark Eyes" (2012), an audio box set from Big Finish Productions. She first meets the Doctor in the battlefields of France, subsequently becoming involved in a chase across time pursued by the Daleks. She is described as having extremely dark eyes, which are revealed to be caused by "retrogenitor particles" which the Daleks have implanted in her in an attempted to destroy the Time Lords. Ultimately the plan backfires when the Dalek Time Controller rewrites time, eliminating the particles. Molly subsequently returns to the First World War battlefields, later being reunited with the Doctor in 1918 in the midst of a Viyran incursion. Following this she once more becomes the Doctor's travelling companion, helping him to defeat the Eminence with the assistance of Liv Chenka, who subsequently joins Molly and the Doctor on their travels. She is mentioned by the Eighth Doctor in the TV mini-episode "The Night of the Doctor". Olla was very briefly a companion of the Seventh Doctor in the "Doctor Who Magazine" comic strips. Olla was a Dreilyn, a heat vampire whose race drew sustenance from draining the heat from other beings, although never enough to kill. She first met the Doctor and Frobisher on A-Lux in the story "A Cold Day in Hell" (DWM#130-#133), written by Simon Furman and drawn by John Ridgway. A-Lux was a resort planet which the Ice Warriors were planning to freeze and turn into a new Mars. Olla helped the Doctor and Frobisher defeat the Ice Warriors, and when Frobisher elected to stay behind, the Doctor took her on board as his newest companion. The Doctor, however, was mildly disturbed by the way Olla kept waiting on him hand and foot. Her stint in the TARDIS was short-lived.
