"To get dressed," she answers.
"And then what?"
"Go interrogate Javi."
He's sitting on his couch, playing Madden, when someone begins pounding on his door. He pauses his game, and vacates his seat.
"I'm coming," he calls as he moves towards the door.
He checks the peephole. He finds a very angry looking former NYPD homicide detective standing outside his door. He unlocks the door, and pulls it open.
"Beckett, what are you doing here?"
Castle smiles, "Since my interrogation was unsuccessful I asked for someone with a little more expertise to get to the bottom of this."
"Can we come in?" Beckett questions.
"Yeah," Esposito nods, folding his arms across his chest.
Beckett enters the apartment first, Castle enters, and closes the door. Esposito moves towards his couch. He points.
"Why don't you guys have a seat? I'll grab you something to drink."
Kate wears a stern look as she shakes her head, "Javi take a seat," she insists.
He takes a seat on the arm of the couch. He looks to his former partner, "What's going on?"
"I got the DNA results back," she reveals.
"I thought that it was too early for DNA," he admits.
"No."
"So what did it say?"
"You're the father," she answers, bluffing.
"What?!" he cocks an eyebrow.
Castle hands her a manila envelope. She reaches inside and pulls out a piece of paper, and hands it to Esposito. He studies the paper, and looks at her.
"I never gave you a sample," he points out.
"I had Ryan get one for me," she lies.
"So you're telling me that the baby you're carrying is mine?"
"Yes," she nods.
"Unbelievable," he shakes his head.
"Why is it so unbelievable?"
"It's not unbelievable, it's impossible," he admits.
Kate cocks an eyebrow, "Impossible? How so? Is there something that you want to tell me, Javi?"
"No," he shakes his head.
"'Sito we know."
He swallows hard, "Know what?"
"I have the recording from your meeting with the blackmailer. I have the video from the night that you went over to Kate's apartment."
"Tell me the truth, Javi. What really happened?" Kate begs.
He looks her in the eyes. He exhales, and then begins, "Nothing."
"Nothing happened?"
"Nothing happened. I never thought for a second that either one of you would believe that it did. I hoped that you would figure all of this out before everything hit the fan. With you in D.C., and Castle here, it didn't go the way I wanted it to. I didn't mean to cause such a rift between the two of you."
Castle speaks up, "We know why you did it."
"You have to believe that I never meant to hurt anyone. I just felt like I didn't have a choice," he looks to Kate, "I knew if I told you that you would never go along with it. I was afraid if I told Castle he couldn't keep quiet. I knew that neither one of you would willingly betray the other. I had to do it to keep you guys safe."
"Kate didn't remember because nothing happened."
Esposito nods, "I couldn't do it. I couldn't destroy your relationship."
"But you nearly did," Kate points out.
"I am sorry I never meant for any of this to happen, but I didn't have much of a choice."
"Who is the blackmailer? Kate probes.
Javi shrugs, "I can't tell you that."
"Why not?" Castle cocks an eyebrow.
"Because they won't hesitate to kill you," Javier reveals.
"They? What do you mean, they?" Kate quizzes.
"This goes far deeper than any of us ever thought. These people are powerful, you can't bring them down with one blow."
"We have to do something," Castle argues.
"Javi I am going to have a baby, I can't have something like this hanging over my head."
"Then I suggest that you walk away. Leave D.C., and come back to NYPD. Stop looking into your mother's case. Stop digging. You have to let it go."
Her nostrils flare, and her voice raises, "Let it go? You just expect me to let it go?"
"If you don't you are going to end up dead."
"I..."
Castle cuts her off, "Is it really worth it? Kate I know how much catching your mother's killer means to you, but at what cost? Are you really willing to sacrifice everything for that? What about our child?"
Her anger quickly morphs into guilt, "I don't know how to let go of this," she tells him, with a pained expression on her face.
Javier speaks up, "Don't let it go, just put it away, for now. Give it time. Let this rest for a while. When the time is right we will catch these guys, but now is not the time."
"I just want to put this to bed. I don't want to have to worry about someone coming after me, or my child. I want this over with."
Castle turns to her, "I know that this has been a lot to handle. I understand if you want some time alone right now."
"Yeah, is there anyone at your place right now?"
"No. Alexis is at school, and mother is working on a play. You can have the place to yourself. I'll catch up with you in a while. I just want to talk to Javi, for a little bit."
"Okay," she agrees.
They watch her as she turns to head for the door. Castle waits for the door to close before he reinitiates the conversation. Once he's certain that she's gone he turns to Javier.
"What do you know?"
"Too much. Castle I have done a lot of digging. I know who most of the pawns in this game are. I think with a little help I could get all of them."
"How are we going to protect her?"
"You worry about that, and I will worry about catching these bastards, okay?"
"Do you need my help?"
"You're too close to her. I don't want this to come back on either one of you. I'll have Ryan help me."
