"Can I ask you something?"
"Yeah," she nods in agreement.
"Why are you still wearing the ring?" his glance falls on her left ring finger.
She stares at him with a look of guilt written across her face, "Because I couldn't bring myself to take it off."
"You are still holding out hope that this will all work out."
"How can any of this work? I betrayed you. I am pregnant, and I am fairly certain that the baby isn't yours."
"So why are you still wearing the ring?"
She looks up at him with hazel eyes, and a heavy heart. She presses her hand to his chest. She breaks eye contact, and answers candidly, "Because I still love you."
"I know. Why do you think that I am here?"
"To reek havoc on my life. Castle you do know that this isn't a case? You can't use a story to explain everything."
"Just because I have a theory doesn't mean that I'm not right."
"In the past you have been right with some of your theories, but you have been wrong way more than you've been right."
"Can I ask you something?"
"Sure."
"What are you going to tell her?"
"Tell who?"
"Your daughter."
"My what? Castle it's way too early for me to know what I'm having."
"I know these things. I am never wrong. Trust me on this. Tell me, what are you going to tell her?"
"I will more than likely be dead, so I am not going to tell her anything."
"Hypothetically."
"The truth. I would tell her the truth."
"What if she hates you for it?"
"She can go live with her dad," she tries to make light of the situation.
"Can you imagine Esposito as a father?"
"No."
"Neither can I."
"As much as I don't even want to consider it a possibility, I have no choice."
"You want me to go?"
"You don't have to, it's late."
"You miss me," he realizes.
"Maybe."
"Kate make up your mind do you want me in your life, or not. I don't want you to think about all the possible outcomes. Just tell me do you want me here, or not?"
"Yes."
Javier enters the room. Castle closes the door behind him. Esposito folds his arms across his chest.
"Why are we in here?"
"Have a seat," Rick points to the chair on the other side of the table.
"Look I know that you hate me right now, but if you are going to do something stupid you should pick a room with less cameras."
"I brought you in here for a reason."
"What is that reason?"
"Have a seat," Castle once again points to the chair.
Espo nods, and walks around to the other side of the table. Rick takes a seat on the chair closest to the door.
"Man, you want to explain to me why we are in the interrogation room?"
"I am going to interrogate you," Castle explains.
He cracks a smile, "Interrogate me, about what?"
"What happened that night."
"I already told you. You know what happened."
"I just have a few questions.
"You have asked me the same questions over, and over again."
"Why did you go over there?"
"She was my partner. I just wanted to make sure that she was okay."
"Why did you bring the tequila?"
"I just wanted her to get out of her own head for a little bit. She is so logical all the time, and love is completely illogical."
"You didn't know that I was going to propose. I never told you that."
"I never said that I did."
"Kate told Lanie that you knew. How could you know?"
"I just had a feeling."
"I don't buy it. What really happened that night? Why did really go over there? Why did you really take that bottle of tequila? What was your plan?"
"I was just trying to be a good friend," he insists.
"I don't buy it," Rick raises his voice.
The door to the interrogation room flies open. Ryan enters the room, with nostrils flaring.
"What the hell are you two doing? We are supposed to be on our way to pick up a suspect. Gates is up my ass because I'm still here. How am I supposed to explain to her that the two of you are in here playing good cop, bad cop? I mean Castle, you're not even a cop."
"I know."
Ryan furrows his brow, "So why is Espo on that side of the table?"
Javier shakes his head, "Because I am the one being questioned."
"About what?"
"Close the door," Rick replies.
Javi shakes his head, "Castle don't tell him."
"Ryan your partner is a cheating S.O.B., and that is all you really need to know."
"Castle what are you talking about?" Ryan wonders.
"Haven't you noticed how awkward things have been around here lately?" Castle doesn't miss a beat.
"Yeah, but as per usual I am the last one to know anything."
"He and Lanie are on the outs," Rick adds.
"And by the fact that you are in here trying to interrogate him, which is completely laughable, because he is former special forces, I am guessing that the two of you have beef with each other."
Castle turns and looks at Javier in disappointment, "Detective Esposito tell your partner what you did, or I will."
"No," Espo shakes his head.
"Do you want Gates to come in here, and kick our asses? Bro just tell me so that we can get out of here, and pick up our suspect," Ryan suggests.
"I slept with Beckett."
"What?! No. That violates everything that either one of them stands for," he looks at Castle.
"Thank you Ryan, I completely agree. It does not change the fact that according to them it did happen."
