Continuity

• The Valiant last appeared in Last of the Time Lords.
• At the end of the episode, when the TARDIS flys 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 was last in Partners in Crime. She appears to be shouting 'Doctor!'
• The Valiant's laser is similar to that of Torchwood 1's used against the Sycorax. (DW: The Christmas Invasion)
• The Doctor is threatened by Luke Rattigan with a gun. A gun was previously shown in Planets Of The Ood by Mr. Halpen and The Doctor told Colonel Mace he doesn't like people with guns standing around him!!

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.)

DVD and other releases

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