(SCI FI Wire) Xena: Warrior Princess star Lucy Lawless, who appears in the two-part season premiere of The X-Files, revealed a few tidbits about her top-secret role to free-lance genre columnist Ian Spelling. The X-Files kicks off its ninth season on Nov. 4 with the episode "Nothing Important Happened Today."

"My character, Shannon McMahon, re-enters [Agent John] Doggett's life," Lawless told Spelling by telephone from her home in Auckland, New Zealand. "They used to be in the military together--in my backstory, they fought in Beirut--and now she's causing a great deal of trouble. You don't know if she's good, and you don't know if she's bad. She seems to be both things at once."

Lawless added that McMahon bears tidings for Scully's baby. "And I spent half my time naked," she said. "Why not, if it looks good onscreen? Of course, you don't see anything, except my well-endowed body double. Let's just say the character's a bit of a water baby, a water babe. She's a nymph."

But Lawless declined to say more. "I feel like [X-Files creator] Chris Carter will come after me, and I'll end up with bloody cement boots on my feet at the bottom of the ocean if I tell you too much."
