Birkhoff (Aaron Stanford) tells Nikita (Maggie Q) that Sonya (guest star Lyndie Greenwood) is Amanda's (Melinda Clarke) mole and not only has Amanda reactivated Sonya's kill chip but she also placed a second mole in Division to keep an eye on her. Nikita, Michael (Shane West) and Ryan (Noah Bean) devise a plan to use Sonya to ferret out Amanda's hiding place and Birkhoff sets a trap for the second mole. Meanwhile, Michael confronts Alex (Lyndsy Fonseca) about her drug use and she begs him not to tell Nikita.
