[on Captain Jack’s on-screen romances] The best kiss, the person I love kissing the most, was Gareth David-Lloyd, who played Ianto. It was just because I felt powerful, because Gareth is straight. Gareth likes the girls and he totally gave over and was passionate with me and everything. Put it this way: Gareth was always happy to see me. And I felt very powerful when that happened. I was like, I’ve got something that you don’t want but it’s still turning you on.
John Barrowman (Captain Jack Harkness)
