Continuity

• The exterior of the TARDIS was rendered white during the events of The Angel of Scutari. It remained as such for the previous trilogy of stories, Project: Destiny, A Death in the Family and Lurkers at Sunlight's Edge.
• The TARDIS with the black exterior was inexplicably seen in a trilogy of solo Seventh Doctor stories, Robophobia, The Doomsday Quatrain and House of Blue Fire, which, for the Doctor, take place between Lurkers at Sunlight's Edge and Protect and Survive. It is also in Project: Nirvana, which takes place just before Protect and Survive.
• Peggy Marsden returns in Gods and Monsters.
