Continuity

• The Valiant last appeared in Last of the Time Lords.
• At the end of the episode, when the TARDIS fly's off, the Doctor says his "What, what, what" line from Donna's first appearence in The Runaway Bride.
• Rose Tyler appears on the TARDIS scanner screen for a split second, she appears to be shouting 'Doctor!' and was last seen in Partners in Crime.
• The Valiant's laser is similar to that of Torchwood 1's one used against the Sycorax. (DW: The Christmas Invasion)
• The Doctor is threatened by Luke Rattigan and by the cloned Martha with a gun. He was previously threatened by Mr Halpen in Planet of the Ood.
• The Doctor thanks Donna and Martha just before he sacrifices his life. He last said this to Donna in The Sontaran Strategem when she was supposedly leaving him.
• This is the first time a serial has continued onto the next one in the new series; as normaly happened in the classic.

Discontinuity, Plot Holes, Errors

• A corridor explodes with Sontarans inside it. This is the same corridor that exploded in the Torchwood episode Sleeper. The corridor in Sleeper was in Cardiff but the one in this episode is in London. A similar mistake occured in Partners in Crime. (Perhaps these buildings are built to the same design.)
• Commander Skorr is killed by Colonel Mace with a pistol, but minutes later he can be seen open skinned next to General Staal in the Sontaran ship. (The second Skorr, however, could simply be an identical-looking clone.)

DVD and other releases

• It will be released on the Series 4 boxset DVD in November 2008.
