In the second episode of the mid-season, Sara gives Nikita her first assignment as a fully fledged agent of the Division. She is asked to assassinate Prince Eric of Georgia at a museum gala in New York City. So, Nikita's job is actually to figure out how to stop the plot to kill him. She hopes she can get some help from the Prince's wife, the Princess, but it turns out she's in on the plot and incapacitates Nikita with a Taser. Upon waking up, Nikita subdues her captor and quickly comes to the rescue of the Prince just as members of the Division raid the gala event under the guise that they are Georgian rebels.
Safe for the moment, the Prince explains his marriage was merely a business arrangement and it's his assistant he truly loves. They're still in danger, but he won't leave the museum without her. The two set to arrange for her, but the Division comes after Nikita and she defends herself with an ancient sword in the museum, and she looks hot while doing it. Next the New York Police raid the museum and try to quell the fake rebel situation. Michael appears on the scene too.
Michael and Nikita both agree they have jobs to do and will try not to get in each other's way. It's tricky for Nikita and Alex to save the Prince while the Division is after them, but in the end they prevail. In the aftermath, Alex is once again the go-between for Nikita and Michael, but both are in the dark about the other's apparent intrigue.
