Thin Ice (audio story)

Thin Ice is an audio play based on the unproduced story Ice Time, which was originally scheduled as one of the stories for the planned Season 27, which was supposed to air in 1990. However, the cancellation of the series made these plans moot.

This story puts into the forefront what the Seventh Doctor's ulterior motive for raising up Ace was: he wished to groom her for entrance into the Time Lord Academy if she was willing to join them. While the Cartmel Masterplan would have designated this as Ace's departure story and Raine Creevey's start as the new primary companion for the Doctor, the audio adaptation skewed from the original intentions of writer Andrew Cartmel and instead saw Ace decline the Doctor's offer and elect to keep traveling with him. The change in narrative allowed Big Finish Productions to keep charting its own course for Ace.

 * Ace first visited 1960s London in TV: Remembrance of the Daleks.
 * Immediately after the events of this story, the Doctor and Ace travel to October 1989 where they are reunited with Markus Creevy and Colonel Felnikov as well as the former's then twenty-one-year-old daughter, Raine. Both Markus and Felnikov take some time to realise that Ace is the same girl that they met in 1967, having not aged a day in the interim two decades. (AUDIO: Crime of the Century)
 * Hhessh mentions "rival factions" of Ice Warriors, and that the militaristic force on Earth are the last "true" Ice Warriors. The Third and Fifth Doctors had previously encountered one of these pacifistic factions on Peladon. (TV: The Curse of Peladon, TV: The Monster of Peladon, AUDIO: The Bride of Peladon)
