Sorry for the late update, we have been a little hung up with the Castle spoilers, Cote de Pablo leaving, and Emmy news, amongst other things. Hopefully won't happen again, we will try our best not to.

DISCLAIMER: WE DO NOT OWN CASTLE OR ANY OF THE CHARACTERS, IF WE DID CASKETT WOULD HAVE BEEN CANON FROM EPISODE 1 AND THEY WOULD LIVE IN A BIG HOUSE WITH 3 KIDS AND A DOG, OK?

Chapter 4

Kate was now in a delirious state of shock and confusion, and she genuinely had no idea as to what he was talking about. Before she could protest, the familiar burning and jolting took over her senses once more.

"Ok, I'm going to run her name and see what pops," Esposito said, as he began to tap away at his keyboard. "I'll cross reference her with Beckett, hopefully should get something."

They waited a few moments and another ping followed by a new window flickering to life on the screen, sporting information about Beckett and the mystery lady. Esposito went to open it, but red lights flashed the words 'COURT SEALED' every time he clicked.

"Damn it, we need a court order!" Ryan exclaimed, annoyed that there was another obstacle in their way when 2 of their own were already in grave danger. Gates however, was already on the phone and had got a judge to subpoena the records. He typed in the code, and new information appeared on the screen.

"Ok, it says here that Beckett's mother, Johanna had a cousin. Her name is Carol Boulton, and she is our DOA," Esposito read out as he scrolled down. "Grew up in New York, had 2 kids, 1 deceased now unfortunately, the other lives in state, married once and divorced, inherited an old bit of an estate from her father.. not much else."

"What's that?" Laine asked as she pointed to a corner of a picture hiding behind the open tab. Esposito complied and clicked on it, revealing an image of a gorgeous ornate blue enamel butterfly shaped pendant, encrusted with what they only could guess to be sapphires and diamonds. It was beautifully crafted; the glassy enamel streaked and pearled, mixing hues of blue and silver in a variety of tones. The individually set stone scattered what natural light there was, creating a look as though the jewellery piece was glowing.

Beckett slowly closed her eyes and tried to regulate her erratic breathing, following her last shock.

"What do you want with that pendant? I don't even know what it's about!"

"Oh Kate, I just told you! Didn't you hear my description? I always considered myself a writer." At the word 'writer' Beckett shut her eyes, blinking back tears. The room she was in was not completely soundproof, and her torture had caused her to scream, loudly too, and she knew he would be able to hear. He had become so protective recently, he wasn't quite the same now.. It hurt her more than the torture itself to know that he could hear it all, and feel so helpless.

"It was supposed to be mine! But no.. it's yours, you're welcome," Dr Collins spat in disgust.

"I don't know anything about it! I don't know where it is or why it's mine, if you say it is! How did I get it? Why have I got it?" Beckett replied. If he was lying, then he was very good, if not then what is this blue butterfly thing got to do with anything. He wouldn't lie though, would he? Not if he wanted something.

"We never had much money growing up. Not like you, with the lawyer mother, who was never strapped for cash. Ok, you weren't rolling in it, but still, you had money. I, on the other hand, did not. I lived in a tiny apartment in the Bronx, which I would never have got out of if it wasn't for my mother's love for yours. They were only cousins, I don't know why they were even close, from what I remember, your mother was a meddling idiot who bit off more than she could chew. But then, my grandfather died and left a bit of an estate to my mother, and also the Blue Butterfly. It's a very important thing Kate, worth a LOT of money. But in her will, my dear old mummy left it to you," he said mockingly, to show her she wasn't worth it.

"But why have you kept me here? I obviously know nothing, and I didn't ask for anything. Just let the people in the other room go. They don't deserve this. It has nothing to do with them," Kate said, trying to think straight even though her brain was a cloud of bright light and fog. She had trouble remaining conscious, every ounce of energy was put into regulating her breathing, and trying to read between the lines of Dr Collins words.

As she blinked back the tears, her eyeballs drew back into her skull as the metallic electricity pulsed through her body, sending her muscles into spasms, turning her world black. As quick as it started, it stopped. Head swimming, she could hear Dr Collins words through the haze, sounding as though he was speaking from the end of a cave, even though he was only mere inches away from her writhing body.

He snapped is fingers, pulling her back from her stupor.

"That was for asking for the hostages to be released. Do you think I'm stupid?"

"No. I think you're clever. If you were stupid, then I would have you in cuffs by now wouldn't I? But then, you should know that you only have 2 ways of leaving this bank. In cuffs or a bodybag."

"Oh I very much doubt that. You were left that pendant. You are going to get me that Blue Butterfly one way or another," he sneered a cocky smile.

Esposito and Ryan sat in the break room sipping their coffee, trying to manufacture a plan to help hostage rescue.

"Ok, so we need to find a way in, without harming the hostages. Castle and Beckett are both in there, so they can probably help in some way," said Ryan, totally oblivious to the fact that their friend and only qualified police officer was currently being restrained and being tortured.

"I think we need to get snipers to take out the main threats in the bank overlooking the hostages," said Esposito.

"Well, in that case, we need at least three snipers up there plus a back up, so that all of them can be taken out at once, so that they don't start to kill the hostages. At the same time, we need a SWAT team on the doors, ready to get the hostages out immediately. After that, another 2 teams need to go in and sweep the bank, and detain any other perps as necessary," Ryan replied, as they both grabbed their coats and ran out of the Precinct, to go back down to the bank.

Castle lay faced down on the floor, legs spread, and hands behind his head. He knew a gun was still being pointed at him, even though he was facing the other way. His cheek was stuck to the floor with a pool of tears that had escaped his eyes, even if he forced them shut, when he heard Kate scream.

How could he let this happen? She was never meant to be anywhere near the bank, if he hadn't come here today, then none of this would have happened. She was too beautiful for this, not that it would matter, her beauty ran deeper than what was visible to the eye. Her hair, her face, her smile..

Castle was wrenched from his thoughts when the sound of glass shattering, bodies falling, and a huge bang releasing a large amount of dirty smoke and a blinding flash of light overpowered the room. His head was filled with the hostage's screams, and the sound of Espo and Ryan shouting Beckett's name. A scream, higher and more piercing than all the others attracted their attention. The 2 cops disappeared towards the back room. It wasn't the same. He knew it was her. But he heard something else underlying in the ear splitting noise. Weakness. Beckett was becoming weak. Castle remained speechless on the floor, his world blurring.
