Nearly 200 years have passed for the Doctor, and as he nears his death at Lake Silencio he decides to visit his friend Craig Owens. Craig has moved in with his girlfriend Sophie and the two are raising their baby son, Alfie. The Doctor arrives just as Sophie has departed for a holiday and is compelled to stay and investigate strange electrical disturbances in the area. He traces this back to a department store, which the Doctor and Craig discover contains a teleporter to a Cyberman spacecraft as well as a Cybermat . The Doctor finds the ship underneath the building and is captured by the Cybermen; Craig follows and is nearly converted to a Cyberman, but he hears Alfie crying and recovers the strength to reverse the conversion. Elsewhere, Kovarian and the Silence strap River into the astronaut suit.
