The team watched Mary gathered weapons from Castle to prepare for a fight. Casey and Sarah are eyeing each other waiting for the perfect timing to attack but Beckman saw them and eyed them not to continue with their plan.

"Mom, what are you planning to do? Why would you want to kill Agent Decker? Sarah said he's a high ranking official. Do you have a death wish?" Chuck asked his mother.

He is so desperate for answer ever since she returned to his life.

"I don't have a death wish, Chuck. They're the ones who wish for me to be dead. I'm sure by now, Diane filled you in Project Clean Slate", Mary answered.

"Yeah and they called it off but if they found out that you're the one who destroyed the Deep Blue Sea and that you're after Agent Decker, they will reactivate Project Clean Slate and they will kill you", Chuck explained.

Mary put down the gun on the table and turned to her son.

"Agent Decker was the agent who shot your father in that video. In this room, only me and Diane know what he looks like. Casey and Sarah only knew him by his reputation so they didn't recognize him when I showed you the video", Mary said which surprised her son. "Decker is a cleaner. The CIA wanted Project Agent X to be cleaned and so he started with your father. Surely, he would've kill me too but he cannot get to me because I am with Volkoff and he sure cannot touch Hartley. I know you think there is another way, Chuck, but there isn't. He killed your father and he will pay with his life", she added.

Mary resumed preparing as Chuck watches her. He's out of words. He doesn't know how he could possibly reason with her to stop what she's planning to do. He's angry that his father got killed and it's CIA's order but he cannot bear the road his mother is walking through now because of it. She's a good person. He knows that. She's a loyal agent and a true friend. She could've turn her back on the agency after learning they have erased her file on their database but she didn't and still continue on doing her mission. At the same time, she's a loyal friend to Hartley. He might be not the same person anymore but she can still see Hartley in Volkoff and she hasn't given up on him yet. Chuck knows all of these and what he's looking at now is the monster her mother is becoming. He knows she will not stop until she kills Decker and she will kill anyone who gets in her way.

"Is this what Dad wants you to do?" he suddenly asked and that made his mother stopped packing.

Mary thought about it. The answer is no. Stephen was a pacifist. He's a scientist. The only reason he was in the business was he's brilliant that the agency took advantage of it. Other than that, he had no other skills to offer the CIA. He's a peace lover. He didn't like violence and death. One time, there was an attempt on his life and Mary killed three men in the process of saving him. Though grateful for her help, she saw the resentment in his eyes for the lives that she took. Stephen wouldn't want her to kill Decker or anyone else for him. That is the truth.

"No, he wouldn't want me to kill anyone. He never did. He asked me to quit a few times but I couldn't because he couldn't get out of the agency so I stayed. What does it matter now? Your father never listened to me anyway. I am betting if the situation is reversed, he might surprise you too", Mary answered bluntly and then grabbed her bag filled with guns.

She was about to leave when the door closes. Mary turned around and saw Casey and Sarah who locked it.

"Please, don't start with me", Mary muttered.

"We cannot let you out. The agency is investigating everyone about what you did with their facility. So far, you're in the clear and the Project Clean Slate has been called off. If we let you out, you're blowing everything and risking putting us and your family in danger", Sarah explained.

"CIA doesn't know you know about Project Agent X", Mary countered.

"Do you think they will not know that you came here? They will find out soon enough and all of us will be dead", Casey exclaimed.

Mary took out her gun and shot the switch to open the door. The alarm went off inside Castle.

"They will not know and they wouldn't dare because they will be busy with something else. I'll call you soon, Chuck", she said and then leave.


Mary is inside a car when Volkoff called her. She picked up her phone and answered.

"My love, when are you coming home? I have an amazing job planned", he asked over the phone with such affection.

"Soon, darling. I just have to finish one thing before I leave. I cannot wait to know all about that amazing job", she answered with her affectionate voice though it doesn't reflect on her face.

Alexei laughed with excitement.

"You will love it. Well, take care, my love and see you soon", he said and then hung up.

Mary put her phone down and looked back at a big house across the street.


Back in the Castle, they are still recovering from Mary's surprise visit. Some are talking about whose fault it is that Mary is going rogue while Chuck is staring at the flash drive his mother left. Then, he got up and plugged it in his computer and started exploring it.

"Oh my god…", he muttered and everyone went to him. "Remember when Mom said the CIA will be busy with something else? Well, here's the reason why. She copied all the files of the agency…everything", Chuck added.

"She must've sent it to Volkoff. She knows he will make use of that and create a new problem that will divert CIA's attention away from she did", Sarah concluded.

Then, Chuck opened the surveillance footage Mary happened to copy from Deep Blue Sea. It's her as she killed the agents on board one by one.

"Oh my god…Mom, what did you do?" Chuck muttered.
