The Castle is in panic mode. CIA thinks it's a terrorist attack what happened with Deep Blue Sea. There's no trace of who did it and the agency is scouring all possible lead on how can someone found their secret facility in the middle of the ocean. All CIA branches and other acquired facility are on lockdown and everyone is under investigation including Castle.
Beckman just got off the phone with her superiors.
"Do they know it's Mom?" Chuck asked.
"No. They don't have a clue just yet. They think it's a terrorist attack and the agency got a lot of names in mind. What the hell did she find in there that sets her off like that?" Beckman answered.
Suddenly, the alarm sounded off and it alerted everyone. Casey and Sarah both took out their guns and got themselves ready. Few seconds passed and there's no one coming in. Morgan smiled and then looked at them.
"I think guys it's just faulty wiring or something. This place needs an upgrade", he joked when he suddenly fell onto the floor.
Mary came in and shot Casey, Sarah, and Chuck with some sort of tranquilizer gun that paralyzed them but kept them conscious.
"Mary", Beckman muttered in surprise.
The three fell on to the floor joining Morgan. Mary then walked towards Beckman who's trying to get her gun ready but Mary is faster and knocked it off her hand and then hit her on her face. She then pinned the general onto the table and pointed her gun on her face.
"Don't you Mary me, you two-faced bitch! You knew he was there all those time!" Mary exclaimed ready to fire the gun any moment.
The nervous Beckman tried to hide it from her friend but she cannot hide it in her eyes.
"I don't know what you're talking about, Mary", she said as calm as she can.
"You think I'll just believe you? They kept him in that awful place for years and used him for their own benefit and when they're done, they just disposed of him like some garbage", Mary continued.
Beckman frowned.
"Who are you talking about, Mary?" she asked.
Mary can somehow see that Beckman has no idea what she's talking about and why she's so angry.
"Stephen…did you know that the CIA kept him in Deep Blue Sea for years when everyone thought he's dead?" she asked.
"No, Mary. I thought he died while he's in his lab", Beckman answered.
Mary put down her gun on the table and took out another gun and shot the four agents on the floor with the anti-dote to allow them to move again.
"Mrs. B…I have to say, that hurts like hell", Morgan muttered as he got up.
Mary doesn't want to let go of Beckman but she knows she doesn't know anything. One of her many talents is reading people when they're lying so she let her go.
"Mom, what is going on?" Chuck asked.
Her mother handed him a flash drive.
"Stick that to the monitor", she instructed and like an obedient son, Chuck followed even though he got a lot of questions in his head.
They all saw the video footage Mary saw in the facility of Stephen tied on a chair and then he got shot by another agent.
Chuck couldn't find the words to react to what he has seen. Mary knows it is too much to let her son saw that but she figured he's a spy now. He can handle it.
"We thought he died", he muttered.
Sarah put her arms around him for comfort.
"He faked his own death as per the agency's request. They kept him there for years to make them serums, weapons, and other stuff. Then, they killed him", Mary explained while looking at the monitor. Her fingers are playing with her husband's wedding ring and Chuck saw it too.
It pains him to see how much his mother is hurting right now.
"That's why you blew up Deep Blue Sea", Casey muttered understanding everything.
Mary scoffed.
"Yeah…among other things", she muttered and then turned to Beckman. "I need a favor", she said.
Beckman wiped the blood from her lips.
"A favor? I wonder what you want right now, Mary. You just blew up a CIA facility", she asked.
"I want Decker, Diane. Tell me where I can find him and you'll never see me again", Mary answered.
Casey's eyes lit up upon hearing his name.
"He's a high ranking official. You take him out, the entire CIA will come after you", Sarah intervened.
Mary turned to her and smiled.
"No, they will not", Mary said and it made the agent curious. Mary then turned to Beckman again. "Give me his location, Diane. You know I will get it one way or another so might as well make it easy for your sake", she said.
"So you'll kill me now if I don't help you? Is that how it works now?" Beckman asked the woman that used to be her friend.
Mary smiled at her and then pointed the gun on her head.
"They killed my husband so yes, that's how it works now, Diane. Now, are you going to help me or do I have to shoot you right here, right now?" Mary answered then asked her back.
