Sarah makes a bargain with the Queen Spider and returns to Earth with the Doctor.
The Doctor escapes from his cocoon, and reaches the mouth of the cave of the Great One, who warns him not to enter due to the lethal radiation within. She orders him to return the blue crystal that he stole, and humiliates him by forcing him to march in a circle like a tin soldier via her psychic power. The Doctor is too overcome by fear to face her, and escapes with Sarah Jane back to Earth in the TARDIS. They meet the leader of the meditation center, the Abbott K’anpo Rimpoche. Meanwhile Lupton’s followers, possessed by the Eight Legs, fire telekinetic force at Tommy, the only person standing in the way of their taking the crystal.
