After the Battle of Demon's Run, Madame Vastra and Jenny returned to the station on the Demons Run asteroid and used alien technology to resurrect Strax. They told him that the station was being evacuated, and offered to take Strax with them back to London. Refusing at first, he finally agreed to accompany them back to Victorian London. Sometime before 1893, Strax became Vastra's butler. (TV: A Good Man Goes to War, WC: The Battle of Demons Run: Two Days Later)
