Sophie (The Lodger)
Sophie was Craig Owens's girlfriend and the mother of their son, Alfie Owens.
Sophie had romantic feelings for Craig, as he did for her, but they never pieced together that they loved each other. When Craig took in a new lodger, she found him very quirky and strange, but was inspired by him to follow her dream of helping orangutans, to Craig's chagrin. One day while the Doctor was at the flat, she was lured upstairs to an attempted time machine ship, which was trying to leave by kidnapping a pilot who had a desire to leave. The Doctor and Craig saved her, with Craig putting his hand on the control panel and revealing that the reason he didn't want to leave was because he loved her. Sophie responded in kind, also placing her hand on the console, and the pair kissed; their combined desire to stay together destroyed the ship. (TV: The Lodger)
Some time after this event, she and Craig moved in together. They had a son, Alfie. (HOMEVID: Up All Night)
Needing a break, Sophie went away for a weekend, leaving Alfie in Craig's care. Unknown to her, the Doctor visited Craig that weekend and had an adventure with them. When she returned home she found the house completely cleaned up and Craig's relationship with their son vastly improved. (TV: Closing Time)
