Nikita fans have to wait until January 27 for a new episode of this thrilling drama, but star Tiffany Hines has a preview of what's ahead when the The CW hit returns:

Major Jaden/Alex drama!

Following the stunning death of Thom on Nikita's midseason finale, Hines says incident gives her character "more purpose, more reason to really go after Alex, and now it's going to get interesting."

"Alex has been on Jaden's radar forever, they haven't gotten along. It's been like this playful catfight, but now it's going to turn serious," Hines told E! News. "I found the thumbprint, the thing she used to break into the office, so I have a feeling that she's a plant and she's working with Nikita."

Just how intense will Jaden get in her hunt for the truth? Hines make it clear, and scary:

"I go to Thom and I confide in him, and the next thing I know he's dead, and he's [set up] as a mole. So now all bets are off. You'll see in the following episode, all bets are off. It's not about, 'I don't like this girl' anymore; now it's a vendetta. 'You killed the man I love, and I'm going to take you down.'"
