In the Rain King, I actually love Mulder's answer when Holman questions him and expresses surprise upon learning that Mulder and Scully are not in fact together.
"I'm perfectly happy about my relationship with Agent Scully."
My first reaction (as a shipper): "yeah, right!" And from the tone of the episode, I'm pretty sure it's meant to be read that way.
But then I started thinking about it more and, knowing Mulder, I don't think he is lying here. I genuinely believe that he is happy about his unique, hard-to-define bond with Scully, even if (maybe) a part of him wants more by then.
