Solon has awakened and assembles a tranquilliser gun. He tells the Doctor that the operation was not complete, only the motor functions are working, the rest on an instinctual level. Knowing Morbius' hatred, he will seek out the Sisterhood. Morbius finds one of the Sisters in some ruins nearby and kills her. The Doctor and Solon find the body and they search the ruins. Morbius attacks the Doctor, but is knocked out by Solon's tranquilliser. As they carry the creature back to the castle, the Doctor tells Solon that Morbius's brain will be detached and returned to the Time Lords.
