S12E9 · The Sontaran Experiment Part 1

Doctor and Sarah escape the camp

As Vural’s men pursue Roth through the camp the chaos creates a rare opening Sarah exploits to free the Doctor and lead him to safety. The Doctor’s quick thinking about transmat technology fails to impress the hostile survivors, and Vural’s distrust hardens as Roth’s escape confirms something is deeply wrong. Sarah’s decisive action introduces her as a pragmatic ally capable of risking everything to protect the Doctor from people who no longer trust or understand him.
