Swedish actress Helena Mattsson has decided to join CW action series Nikita Season 2 a few days ago. She’ll play a recurring role.

As we know, Helena will play a smart female politician Cassandra in the series. Michael had a relationship with her when he worked for the department. Now he found his revenge action has threatened the life of his old love, so he decided to save her.

Mattsson played the part of Irina in ABC’s established soap opera Desperate Housewives, then she guest starred in The Mentalist, Detroit 1-8-7, Two and Half Men, etc. Although war correspondent Hannah in the Boons left FBI special agent Booth, her actor Katheryn Winnick is not free. She will guest star in CW action series Nikita.

It is reported that Winnick will show up in Nikita Season 2, episode 4, playing former agent Kelly in the service. While she was performing tasks with her partner, they messed up. Nikita ran away while she was locked up in Turkey secret prison. Many years later Kelly escaped successfully. I’m afraid someone’s got to be in trouble.

In Fox’s crime series Bones last year, Winnick played the war correspondent Hannah, who was known by Booth when he was performing overseas task. They have been really intimate, even made Brennan quite unpleasant for a time, but his proposal frightened her away.

Nikita Season 2 will come back on September 23rd.
