Myths

• The Sontarans need the gas from the cars to make the earth habitable for themselves.
• A Rutan army will appear in flashback.
• Details of the Brigadier's whereabouts are revealed.
• The Sontarans steal the TARDIS.
• UNIT will launch a nuclear strike. This is highly likely as the trailer for this episode is set around a countdown at [one of UNIT's bases. Also during the trailer Staal states that: "the planet is going nuclear".
• The Valiant will be put to good use by Colonel Mace.
• Donna will kill a Sontaran by the Probic Vent.

Continuity

Discontinuity, Plot Holes, Errors

• In the next time trailer, a corridor is seen exploding with Sontarans inside it. This is the same corridor that exploded in the Torchwood episode Sleeper. This is not a plot hole or error. It is common for TV shows to make use of sets more than once to save on the budget. Also the corridor could have been rebuilt.

DVD and other releases

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