CSU searches the house Kate was in. Castle is standing there, helpless. He can't do anything to save the love of his life. After a while, they find blood. "Over here, I found some blood!" One of the CSU people finds the blood on the airshaft ventilator. He swabs it to check who's DNA it is. Castle sighs as he hoped the blood isn't Kate's. When the CSU person looks inside the airshaft he sees a letter. He grabs it and unfolds it, against all rules. "Mr Castle, it's addressed to you." Rick sighs. After so much experience, he knows letters like this are not a happy ending. He starts reading it and if eyes fill up with tears.

"Dear Rick,

I don't know how much time I have, even to write this letter. What I do know now is, that I'm in this. And the only way I'm gonna make it out alive is to see this through. I'm sure everyone is looking for me, and if they figure out I was here, CSU is gonna search this house. They're gonna look for blood and they will find it which will lead them to this letter. Babe, it's your letter. And I hope you never have to read this, that I can tell you all of these things in person. But if something happens, and I don't make it, I need you to know that our partnership, our relationship is the greatest thing that has ever happened to me. You're an amazing man, and I love you with all of my heart.

Always."

Captain Gates, Esposito and Ryan stand by his side. The worried look on their faces tell more than a thousand words can. After finishing it he passes the letter on to Gates. Tears escape his eyes, but he refuses to believe Kate is dead. He knows her, she is strong, she is still alive.
Back at the precinct, Castle is sitting at Beckett's desk, watching the empty chair she always use to sit on. He can help but think in the past time, even as he convinced himself she is still alive.

"Mr Jones wants a word." The man who picked Beckett up leads her to the face she knows as 'Mr Jones.' Guarded men stand guard, as they watch her every move. She is assigned to a special assignment, to kill a man. When they drop her off at the house of the person she needs to kill, she goes inside. She is afraid but doesn't show it, as the cop is still inside her. The man sees her coming in through the TV. He looks back and Kate puts her finger in front of her mouth, making a 'sshht' gesture. "I'm going to tell you what to do and who I am. If you don't, we both end up dead." She puts the gun down and runs to the kitchen to get ketchup and beet juice. She covers the man with it. "Now I need you to lay still when I come back. My name is Kate Beckett, I'm from the 12th precinct. I'm supposed to kill you but I won't, unless you do what I say, or they will kill you. They want proof of me killing you. Tell the police what I just told you." The man lays down on the ground and Beckett fires two shots. She rushes back to the car that's still waiting in front of the man's house. "It's done."
"Show me." As they walk back in to the house, all they see is a dead body. She did what she had to do to meet Lazarus. They promised they bring her to him. The package was delivered, without any issues. They take her down to a basement. They tell her he likes it there, but she isn't too sure. When she comes downstairs, she sees half naked women counting money. She knows the money is not legal. What she doesn't know if who she's up against.

As she walks in the room after they told her to wait, she sees blood draining down the drain, afraid that will be her blood. As she stands face to face with Lazarus, he isn't too amused. He has seen her before, trying him to pin him against the wall, as she broke the interrogation room mirror doing it.
"She's a cop," he says, as he walked towards her, slowly. She accused him of murdering her mother. "Simmons," she whispers, terrified. "Torture her," he commands. And as faithful his employees are, they do what they're told. They put Beckett in front of a bucket of ice water, keep her head under water, trying to get her to talk. Her lungs are burning, she's tired and she doesn't know how much longer she can keep this up. After collapsing, Lazarus commands to leave her for dead in the woods, and bury her in a nice deep hole in the ground. One of the men picks her up and forces her to walk with a gun sticking in her back. Tired as she is she does what she's told and walk into the woods. Exhausted she paces forward, stumbling over her own feet. Than, the man puts his feet in front of hers, as she falls down the hill. She gets up, facing her so called destiny. But then, something out of the blue happens, the man who was forced to kill her, falls dead on the ground. She sees the real Elena standing in front of her with a knife, telling her Lazarus ordered her to keep Beckett alive. As Elena walks away, Beckett collapses and passes out.

Hours pass by and Castle still didn't hear anything from or about Kate. He's worried sick and stayed the night at the precinct trying to come up with a theory why this could've happened. It could've happened to Elena as she never knew what she was up against. She wanted to be freed from this horror. She never knew who was behind the texts, all she knew is that she never wanted this again. At least that's what they could tell of the video Kate watched earlier before going undercover. Castle watches the tape over and over again. "What is Elena isn't who she says she is?" Ryan and Esposito look at each other. "What do you mean?"
"I mean, what if Elena is in this together with Lazarus, or whoever is behind all this?"
"It's possible, but at the moment, everything is."
"Or, what if Lazarus is someone who knows who Kate is. That they discovered she is a cop." He sits down after saying that. "What if…" Ryan cuts him off. "Don't do this to yourself Castle. Don't go after 'what ifs' when we don't even know that's the case." Castle sighs as he knows Ryan is right. Now, he must be strong for her. He knows she knows it, but isn't so sure how long he can take this.
