"Enlighten me," Castle insists.
"I am the one who put him in prison."
"For life?"
"No," she shakes her head.
"Dreams are your subconscious telling you something," he points out.
"If it was him that means that my son is probably in a shallow grave somewhere, and that I'll never find him."
"What makes you say that?"
"Miguel wasn't a drug dealer."
"Did he have a son named Felix?"
"Yes. He blamed me for his death."
"Why?"
"Miguel was a single father. When he got sent to prison his mother took his son. Felix drowned in a pool when he was a fifteen months old. It was an accident, but he blamed me, because he thought if he had been there he could have stopped it. His mother was hard of hearing. She didn't hear Felix fall in the pool. She had run in the house to get a towel, not more than thirty feet away. She turned her back for a minute. She couldn't save him."
"Who did Miguel kill?"
"Felix's mother."
"Why do you think that Miguel took Dominick?"
"For revenge, but I don't even know if he was out of prison then."
"Why would Miguel want to take Dominick?"
"Because Dominick was close to Felix's age. He was about a year younger."
"Did he know that you had a son?"
"He asked to see me when his son died."
She takes a seat in a small room, with a table, and two chairs. She looks at the criminal in front of her. He's got thick dark hair, and bright green eyes. He wears an orange jumpsuit, and chains.
"I don't understand why I'm here. You didn't want to confess, earlier."
"I wanted to tell you something."
"Tell me what? The truth?"
"My son is dead. He is dead because you put me here. If I were out he would still be here."
"I'm sorry you feel that way."
"You don't get it do you? Can you imagine having your son ripped away from you? He was fifteen months old."
"I wouldn't want to."
"Detective do you have children?"
"Why am I here?"
"You do," he realizes, "A boy, or girl?"
"I did not come here to talk about me. You said that you wanted to confess."
"Tell me the truth, and call the D.A. I'll tell you everything."
"I have a son."
"What if you didn't, anymore?"
"Are you threatening me?"
"No I'm just asking."
"I wouldn't know what to do."
"My son was my whole world. What am I going to live for now? Huh? You took my freedom, and you took my son."
"I didn't do anything. You are the one who killed Felix's mother. You put yourself here."
"Why did he kill the mother?"
"He caught her smoking crack."
"So he killed her?"
"She was in the backyard, and she had left Felix in the backseat of the car. It was the middle of July. Luckily he was only in the car for a few minutes before Miguel came home. He put Felix in his crib, and he went outside to talk to Emily. She had been clean for over two years. He was angry. They argued. He shoved her, and she hit her head on the table."
"It was an accident?"
"Then he picked up a brick, and he hit her with it over, and over again. He went in the house he washed his hands, packed a bag, and took Felix to his mother's house."
"What kind of a deal did he make with the D.A?"
"I don't know. I left before she got there. I went home to be with Dominick."
"We need to track this guy down."
"He's probably out by now."
"We should find out."
She shakes her head, "Castle this is my burden to carry, not yours."
"You have been carrying this one on your own long enough."
"I need to do this myself."
"Which is you saying that I need to back off."
"Yes," she nods.
"Ok. I can respect that."
"Thank you."
"Can I ask you something unrelated to murder?"
"Yes."
"Something you said has been bothering me."
"About what?"
"That you spent every Christmas since you were a rookie at the precinct. What about after you had Dominick?"
"His first Christmas he was only a couple of months old. Unfortunately it was actually my turn to work."
"And his second Christmas?"
"I got up with him on Christmas morning to open presents early, and then my dad picked him up, and took him to the cabin."
"So you didn't spend Christmas with him?"
"I picked him up after I got off work, and we played with all of his toys. He was perfectly happy with my dad."
"What were you planning to do when he got older, and was big enough to realize you were gone?"
She shrugs, "I don't know."
"I mean how would you explain suddenly not working on Christmas?"
"I would have come up with something. Are you questioning what kind of parent I was?"
"No that wasn't it at all."
"Then what was it?"
"I don't know."
"Castle if you have something to say, then just say it."
"I understand why you would want to work on Christmas, now."
"What do you mean?"
"I can't imagine not spending Christmas with my kid, and if she weren't with me..." he trails off.
