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.
