Chris Owens, who plays the mysterious G-man, hinted in a TV Guide Online chat that Spender might get killed in the conclusion of the Fox show's tell-all two-parter (Sunday, 9 pm/ET). Asked what scares him in real life, Owens replied, "Unemployment. I'm facing my fears next week!"

Other than that little tease, Owens was suitably secretive about the episode. He did, however, confirm that viewers would get the skinny on the abduction of Agent Mulder's sister, Samantha.

Speaking of Mulder — why does Spender have such a problem with the sexy investigator, played by David Duchovny? "Mulder's taller," Owens explained.

The actor added that he doesn't mind being loathed by loyal fans of Mulder and Scully. "Hate me, baby," he said. "I love it!" — Susan Campbell Beachy
