Once Sarah Jane has analysed that the Bane ingredient was sentient, she activates her computer, Mr Smith – after some shouting by Kelsey – and contacts Mrs Wormwood and politely requests that she leaves Earth. Mrs Wormwood refuses, and in retaliation takes control of the majority of the human race. Sarah Jane races to the factory, but cannot enter until she drives the bus into a wall. Mrs Wormwood reveals the Bane Mother, and explains the Archetype is a conglomerate of human DNA designed to be investigated so that "Bubble Shock!" could be improved. The Archetype uses an alien communicator Sarah Jane had been given, realising that the signal would be strong enough to kill the Bane Mother, and Sarah Jane, Maria, and the Archetype escape as the factory explodes.
