She is a dancer who was smuggled to the United States.

She had a deal with Michael. Michael helped her get a U.S. green card (because Michael has U.S. citizenship, Nika can also get a U.S. green card after marrying him), and she was responsible for helping her get a U.S. green card when Michael went to jail. Later, he helped with some things, such as giving a "credit card" to Michael in prison, and later helping him steal the key to the infirmary.

There were some scenes of her in the first 4 episodes of the second season, but they disappeared later.

She also helped Michael and Lincoln a lot when they escaped from prison. It seemed that she really loved Michael, but she also knew that Michael loved a female doctor and felt that she was just being used. In addition, she also coveted money, so she still had the idea of ??betraying Michael. This plot probably ends at the end of episode 4 of season 2.

As for this role, there was no explanation, and then nothing happened. Michael and Lincoln continued to flee to Mexico, and she seemed to go home very hurt~

Personal I think Nika is quite affectionate and kind, and the idea of ??betraying Michael in the end was just because she felt that she had been used and let down, so she was very hurt.
