The suspect looks like he has passed out, his head resting on the interrogation room table, when Beckett and Castle enter the room.

Castle wrinkles his nose and mutters, as they take their seats opposite "Oh, this is going to be pleasant."

"Castle, focus. Let's get the job done," Beckett snaps at him.

"Ok, Ok. Just saying." He turns his attention to the man across the table, "Anything we can get you? Coffee? A breath mint?". The man slowly raises his head, attempting to focus his eyes at the short distance, looking decidedly blue. Castle leans back mildly repulsed, "A bucket perhaps?"

"Castle..." Beckett warns and throws him a dark look, although she is also sharing some of his aversion. "So, your ID card here says your name is Kaido. Is this correct?"

The man rocks slowly back and forth on his seat, his eyes partially closing, and slurringly speaks, "Kaido? That can't be your name. Thish ish my name." With that, he falls forward once more, his head crashing against the table.

Castle taps the table with his fingers and looks to Beckett, "Think it would help if we poured a bucket of cold water of him?"

"Sober him up quicker?" Beckett asks with a smirk looking back at her partner.

"Yeah, that, and maybe get rid of some that god awful smell." Castle says and covers his nose with his hand.

Beckett rolls her eyes and leans over the table, lightly smacking the head of the semi-conscious Kaido. "Hey Kaido! Wake up!" The man once more raises his head, and stares at a point around four feet past her.

"Yeah? That's me. Can I help you?"

Beckett, pronouncing each syllable slowly, asks, "Why did you kill your brother?"

Kaido, swaying on his chair, starts to scratch his armpit. "I don't know man. Because I wanted to?" he answers with drowsy smile on his face. "All I remember is pulling up to the car, ripping out my gun, and ...and firing at him" he raises his arms and starts imitating shooting "Phew, phew, phew!"

Castle's eyes go big, "Whoa. Damn Beckett, he might have actually done it."

"Hold ya horses there, Castle." she thinks to herself that nothing is that easy. "OK Kaido. Go through it with us. Take your time".

"Well, let me see." Kaido snorts, clears his throat and drawls, "My brother, right, he ish a right royal pain in the ass. Always like 'Oh why can't you be like Kalev, Kalev is sho talented, blah, blah, blah.'" The disdain was plainly evident. "Sho, I was tripping out today, and I thought to myshelf, 'Why not just kill him?'". At the last comment he grins stupidly. "So I remember getting this awesome bike, grabbing my gun and..."

Kaido pauses for a few seconds. "And what Kaido?" Beckett is frowning now, as Castle peeks at her out of the corner of his eye.

"Well I shot him." Confusion appears across his face. Castle snaps his head back to the suspect. "Well at least I think I shot him. Yes. Yes. I must have shot him." He nods to himself and smiles once more. "Any chance of a coffee? Seem to eaten something bad I think."

"Yes, of course Kaido. It was the food." Beckett states sarcastically.

Castle once more glances at Kate as she rolls her eyes. He can't suppress his delighted smile.

Beckett notices Castle's smile in the corner of her eye and she turns to him "What?"

"Uhh, nothing. I was just, ah ...thinking when you do... umm never mind." He needs to recover the situation quickly so he changes the topic really fast. "So you are tripping out Kaido? What is the drug you cool guys are doing these days?"

Beckett is still glaring at Castle who is doing a bad job of ignoring her. "What is going on? He is acting really weird today…" Her attention is drawn back to Kaido, who is now singing.

"Lucy in the Shky with Diamonds. Lusy in the Sky with Diamonds. Lucy in ...in... " Kaido's eyelids droop down and he slowly falls forward, his head hitting the table once more. He then starts snoring.

"I think he's out for a bit now." Castle bends down to see Kaido's face, which he realized too late, was a mistake. His breath was still god awful. "So, he's coming down from LSD trip," he states.

"How did you come to that conclusion?" the detective asks with surprise on her face.

"Lucy in the Sky with Diamonds? The Beatles?" Castle looks at her with hope she could recognize the reference. She clearly doesn't. He smiles and continues with explanation, "Urban legend has it they write that song about LSD they were using at the time. He started singing it when I asked him about the drugs."

"Ahh, I see. Know this from experience?" Beckett is smirking now, but Castle is quick with his reply.

"Nope. Never needed them or been tempted. That is the start of the walk in the valley of death." He winces as he looks at their snoring companion. "What are we going to do with him?"

"We'll hold him here. At least till he sobers up. LSD though sends you delusional. Who knows if he did it or not?" she muses as they rise from the stools together and head out from the interrogation room in unison.

"That was … awkward." Castle sighs, leaning back in the sofa.

They are sitting in the break room, after the short time spent with the brother of the victim. Beckett is sitting on the chair and she is looking through the newspaper that had been left on the table. Castle, on the other hand, is sitting on the couch, resting his head against the wall and he is pinching the bridge of his nose.

"The interrogation?" she asks, not lifting the gaze from the newspaper.

Castle nods and hums "Hmhmh."

"If it makes you feel better, this interrogation is somewhere on the top of my weird list too." she says raising her eyes to him for a moment.

Castle snorts out a laughter. "Never had a junkie in your interrogation room?"

She throws a glance at him that says 'Really?'"I have had junkies there before, but none of the junkies never openly confessed that they killed somebody. Usually they try to deny everything." she says calmly.

"Do you think he actually did it?" Castle asks, suddenly leaning forward, placing his elbows to his knees.

She pretends to think about it for few seconds and sighs out exaggeratedly. "I am pretty sure he didn't do it."

"Really?" Castle is a little bit surprised. "Why not? He seems to have the memories of the shooting." He pauses. "And he seems to have a motive for killing his brother too."

"And what is the motive?" she asks, her voice seemingly bored.

"He really, really hated his brother?" he states, but it comes out like a question.

She smiles and tries to bring him down from his fluffy cloud. "Yea, I don't think he was capable of killing, judging by the state he is in now." She closes the newspaper promptly and stands up. She eyes Castle for a second, takes her cup and walks to the coffee machine. Placing her cup to the holder, she refills it with the hot and steamy beverage. She takes the cup and turns herself around again to look at Castle, who is eyeing her intently.

"Wanna refill?" she asks.

He nods slightly. She smiles again and walks to the table and takes his cup. After refilling it, she walks to the break room couch, where he is sitting. She extends her arm with his cup and he takes it with a slight thank you nod.

"Move" she says after a moment of silence. He chuckles and shifts himself, till there is some room for her to sit.

They lounge there together. Sipping their coffee in unison and enjoying the quiet moment. Esposito and Ryan have gone to the bank to retrieve information about the victim and his financials. Beckett decided that they needed to look over the workers of the Consulate, to see if they had missed something. Since they had spent over an hour on the files, it was mutual consent that they all needed a break. So, there they were, sitting and enjoying their coffee.

After observing the room, she turns herself to face Castle, when she notices that he had just done the same. They sit there, looking at each other, a slight smile on their faces. Just when Castle lowers his cup and opens his mouth to say something, there is a slight knock to the door.

There is a woman standing there uniformed escort just behind her. She has pretty blonde hair and face that has too much make-up. She tentatively steps in and asks "Excuse me, are you Detective Beckett?"

Beckett stands up fast and walks to the girl. "Yes, I am. How can I help you?"

"Are you investigating the murder of Kalev Järvesoo?" she asks, voice shy, almost whispering.

Beckett gets more curious about the mystery woman that stepped inside the room. "Yes, we are investigating his murder. Can we help you?"

She takes few steps further inside the room. "I think I can help you." She pauses for effect. "I think I know who the killer is."

Castle and Beckett stare at her; both have the same kind of confused and surprised faces. They turn to look each other in unison. Castle mouths to the detective, 'What the hell is going on?'
