Booth’s polarizing ex-girlfriend Hannah is back, and Nikita‘s got her!

Former Bones lightning rod Katheryn Winnick has booked a pivotal guest spot on the CW drama, TVLine has confirmed.

She’ll play, Kelly, the athletic, tough, and no-nonsense former partner of Maggie Q’s titular character who has just escaped a high-security prison in Turkey. Kelly blames Division for letting her rot in jail, and since Nikita abandoned her and went rogue, chances are their reunion will be a tense one.

E! Online first broke the news.

Winnick will appear in this season’s fourth episode.

Nikita‘s second season kicks off on Friday, Sept. 23.
