'X-Files': The Mulder-Scully hookup

Season one: The romance

Tender moments: In the very first episode, Scully and Mulder huddle up in motel room as he confesses his obsession with UFOs and starts her down the long path from skeptic to believer. Things between them remain strictly professional, with both agents taking it to such an extreme it’s an emotional breakthrough for Mulder when he uses Scully's first name, Dana, while trying to comfort her after her father's death.

Splitting up already?: The X-Files are closed down in the season finale and Mulder and Scully are assigned to different duties.
