Sophie (The Lodger)

Sophie was a friend of Craig Owens. She did have romatic feelings for Craig as he did for her, but they never did piece together that they both loved each other. She along with Craig took on a new lodger in their flat. This lodger turned out to be the Doctor. She found him very quirky and strange, but was later inspired by him to follow her dream of helping animals, much to Craig's chagrin. One day when the Doctor was living at the flat, she was lured upstairs to a time machine attempting to kidnap a human pilot. The Doctor and Craig saved her, with Craig, at the Doctor's insistence, placing his hand on the control panel. When asked by the Doctor why he didn't want to leave the flat, Craig replied that it was because he didn't want to leave Sophie, proclaiming that he loved her. Sophie responded in kind, placing her hand on the console and kissing Craig, which resulted in the destruction the time machine. As the Doctor left, she and Craig saw him off. (DW: The Lodger)
