I feel like my poor knowledge of Doctor Who is letting me down here, because I bet that there is an older Doctor who would be a perfect match for Scully -- not in a romantic way, necessarily, but Scully needs someone who is not Mulder around whom she can relax, you know? And I don't see that with any of the newer Doctors. Although Scully/Nine would be an interesting pairing, at least in a postapocalyptic way. In fact, I may need to think about that some more.
