...when it's revealed that Alex's mother is still alive as she makes her way back home in Russian. It's when we see that it's Sarah Clarke (24) is playing her. Ever since the debut of Nikita, I have been waiting for her to pop up somewhere down the road, given the fact that she is married to Xander Berkeley (Percy) and they have worked together before on 24, CSI and The Booth At The End. It was only a matter of time before they added Nikita to their list. I just never thought it would be a plum role like that of Katya Udinov. I'm sure they will set it up that she and Percy of a relationship that is more than...business.
