Description: It's her son Sam's birthday and Kiera is out of sorts. Vancouver PD has a new police chief and Insp. Dillon is replaced by Insp. Nora Harris whose main task is to find the mole in the department. Dillon warns Kiera to watch her back and she is soon being interrogated by Harris and CSIS agent Gardiner. When things get a bit testy with Gardiner, Kiera finds she's been taken off line by one of her built-in programs, a cognitive therapist, who cuts her communication with Alec in order to conduct a psych evaluation. The program tells her that it will erase her memories if she doesn't calm down. Kiera helps Betty get out of a jam. Matthew shows Alec the state of the art lab he's set up for him and Alec finally agrees to partner with him. Jason gives Alec a series of diagrams about time travel.
