The Paternoster Gang are in a spaceship that is going to crash in London. While Jenny Flint and Vastra guide the ship into water, Strax sends a message to Sontar on the topic of the Doctor's ability to regenerate. His remarks include short details about each of the Doctor's incarnations known to date. As he reaches the end of the message, he is interrupted by Vastra and told that they're about to parachute off the ship, telling him that "something impossible" has been sighted in the River Thames.
