The Quarks have begun work on drilling the outer boreholes. The Doctor and Jamie are captured by a patrol of Quarks and taken to the Dominator ship for questioning and scanning. A scan of Jamie is presumed to apply to them both and to the Dulcian race as a whole, who are thus described as possible but not definite for conversion into a slave force. During an intelligence test, the Doctor feigns stupidity to prove their worthlessness. He also fails to use a weapon from the Dulcian museum, falsely claiming such military technology has been lost to the Dulcians. The Doctor and Jamie are freed as worthless idiots.
