I do not own Rookie Blue.
This is after the season three finale. Before we know what Nick and Andy were undercover as however Nick is not in this story. Before Andy left she left a message on Sam's phone saying 'I love you to but I'm going undercover. I shouldn't be telling you but I really had to.'
"1519 requesting assistance to 235 Brookline. It's a warehouse suspected to be a base of human trafficking operation" Cruz said into her radio.
"1519 This is Detective Swarek, wait for my team there on there way there as we speak. This is my takedown."
"Yes sir." Cruz said back within minutes the team was there and they swarmed into the warehouse. Cruz goes in and tries to stop a runner. She tackles her.
"Your making a huge mistake. I'm a cop" the person mumbles.
"Sure you are!" Cruz then cuffs the girl and then walks to the squad with her. When there Oliver notices who it is.
"Cruz go check and see if there okay." Oliver says and Cruz does so. "McNally we have to bring you in so when we get there elbow Cruz and I'll see this so I will get mad and take you to an interrogation room." Oliver whispers to Andy. She winks to him. He puts her in the car and when Cruz gets back they head back to the barn. The entire way Andy was complaining about being wrongfully arrested. When they get there Cruz brings her to booking with Oliver and once they get into booking Andy elbows Cruz in the gut hard. "That's the last straw your going to interrogation. Cruz when your okay help with booking" Oliver then takes Andy into the bullpen. As the two head to interrogation Sam spots them.
"Oliver what in the world is going on here" Sam screams.
"Marlo arrested her at your bust!" Oliver says not stopping and treats Andy like she's another criminal being brought into interrogation and puts her in Interrogation 1 and then leaves.
As Oliver passes the observation room Sam pulls him in. "Oliver that's Andy!"
"I know that Sam. That's why when I first saw her I told her to elbow Marlo so I had an excuse to take her to an interrogation room so her cover wouldn't be blown." Oliver says.
