26 December

On 26 December 1899, the Fifth Doctor and Nyssa watched a Boxing Day mummer's play in Stockbridge. The play recalled events seven centuries earlier that the Doctor and Nyssa were soon to live through: overthrowing the Rutans who inhabitted Stockbridge Castle. Upon interacting with the Doctor, the actor who played the dragon recalled the experiences of his ancestor Osbert — a Rutan clone — and went went under Rutan control. After the TARDIS crew lived through the 1199 events, they returned to 1899 when the Rutan ship exploded (AUDIO: Castle of Fear) and they woke up in Stockbridge on 4 August 2009.
