Ellen: I get the feeling you're not used to someone taking care of you.
Mulder: Well, that has a-- a vaguely pathetic ring to it.
Ellen: No, I just mean that I didn't notice a wedding band.
Ellen: Do you have a significant other?
Mulder: (Considers for a moment, smiling almost impercetibly) Um... not in the widely understood defintion of the term.
Ellen: Oh. Well the right woman will come along and change all that.
