Nikita (Maggie Q) and Michael (Shane West) try to help Carla (guest star Erica Gimpel) remember her past, which holds the key to taking down Division. Carla recounts the night Nikita was arrested and Nikita is stunned at what she learns. Meanwhile, Alex (Lyndsy Fonseca) shows up at a Zetrov press conference where Semak (guest star Peter J. Lucas) is speaking and announces that she's Alexandra Udinov. Alex demands a trade -- her mother for the empire. Melinda Clarke, Xander Berkeley and Aaron Stanford also star. Michael Robison directed the episode written by Albert Kim.
