In 2011, Craig Owens awoke to find the Eleventh Doctor gone following the events of the day previous; the Doctor went to Sanderson & Grainger on his own to battle the Cybermen. Craig joined him and was almost Cyber-converted, but managed to reverse the process half-way through when his son Alfie's cry rebooted his emotions. This also caused an emotional overload for the Cybermen; their ship was destroyed in the explosion. Despite supposedly having little time to live, the Doctor then travelled back a few hours to clean up Craig's house before Sophie returned, and then left for one last trip in his farewell tour and to finally confront his death.
