Lyndsy Fonseca and Maggie Q

Nikita's inside man may soon betray her boss.

As TVGuide.com first reported, Alex (Lyndsy Fonseca) will have a run-in with the head of the Russian sex trade ring into which she was once sold. He'll give her an unwanted taste of her old life by drugging her.

Once Alex is returned to Division, Amanda will attempt to use her fragile and drug-addled state to dig up secrets. Instead, Alex will have a vision. She'll see a future in which she is working against Nikita (Maggie Q).

Does that mean it will definitely happen? "I don't think it's out of the question," Fonseca says of the possibility.

"We're doing this episode where we get a glimpse of a possible future Alex and why she turns out that way," the actress continues. "It's not like one day she'll wake up and say she's evil. It happens over time. You grow, you change, you kill, the killing becomes easier. Thom's kill was just the beginning."

Nikita returns Thursday, Jan. 27 at 9/8c.
