Ok, now I *really* need to rewatch that. The way I remember it, in the end they agreed to go their separate ways. They did kiss, yes, because they obviously love each other and always will, but Mulder couldn't offer Scully what she wanted (a steady, *normal* relationship), and Scully couldn't do what Mulder wanted, which was to just take off, the two of them together, and never look back.

Come to think of it, it may all be due to the fact that I was forced to see this dubbed in Spanish. I never do that. Dubbing is dreadful, they actually change the meaning of words and whole sentences just to make them fit the movements of the actors' mouths...
