Rookie Blue is back this Thursday and fans may get to see if Andy and Gail's friendship can be fixed.

In last episode, "You Are Here," Andy revealed to Gail that she and Nick hooked up. While it may not have been the perfect timing to tell Gail, as she was in the hospital suffering from an allergic reaction, Andy couldn't hold back the secret any longer. She thought that by telling Gail would be the best solution, but the situation didn't end like she wanted it to.

"I'm really happy we're friends, and I would never want to do anything to jeopardize it," Andy told Gail.

After procrastination, Andy told Gail, she "slept with Nick." Surprisingly, Gail reacted calmly.

Towards the end of the episode, Gail told Andy that she broke the friendship code by sleeping with her ex boyfriend.

While Andy and Gail may attempt to avoid each other, fans will get to see a different side of Division 15 in this week's episode, "Deception."

Marlo has an obsession with Kevin, the man who has yet to be found guilty of kidnapping Chris' son. Last week's episode left off with Marlo stalking Kevin, as she was watching him from outside his house.

Despite Andy and Nick new relationship, she will work with Ben unscramble Marlo's unprofessional conduct before everyone finds out.

In the below video, Andy catches Marlo in her car going through Kevin's records. Marlo is convinced that because she "looked him in the eyes," he is guilty of kidnapping other children.
