Doctor uncovers Ogri origins and Vivien’s plan

In the ancient Stone Circle, the Doctor confronts Vivien Fay’s transformation into the Cailleach, who reveals she has captured Romana and taunts the Doctor with a forcefield barrier. The Doctor deduces her true identity and intent, then sees through her illusion to address the missing stones. This leads him to identify the Ogri as an ancient entity linked to blood sacrifice on Earth, exposing Vivien’s ancient scheme. With Romana trapped and global disaster imminent, the Doctor and Emilia split forces to gather tritium crystals, the only means to stop Vivien’s plan and rescue Romana from hyperspace. The Doctor’s revelation reframes the entire crisis from a local abduction to a planetary threat rooted in prehistoric forces.
