A.N. So I have some time to spare at UNI today so I figured I would treat you to another chapter. I am working on the next few and I promise that it gets really good. Especially this chapter. Please review.

After hearing a loud thump come from the break room, the boys came rushing in only to see Castle unconscious on the floor, Kate tapping his face to try and wake him up while still talking on the phone to someone.

"Thank you for getting back to me Doctor. I will talk to you later. Castle's just fainted." She stated, tapping his cheek again.

"Oh, you should put his feet above his head and he will wake up soon. Goodbye Ms Beckett." The Doctor said, hanging up the phone, Kate hanging up on her end too, putting her phone on the floor next to Castle's head.

"Ryan get his chair. Esposito, get him a glass of water." Both boys did as they were told and rushed off to get the items they were instructed to get. Ryan came back quickly with Castle's chair while Espo filled up the glass, handing it to Kate.

"Ok, I need you guys to get his legs and put them on the chair." She instructed. Esposito bent down next to Castle and lifted his legs up in the air while Ryan slid the chair in under them. "Thanks guys." Kate told them, both of them taking it as a sigh to leave, while Kate stayed and kept an eye on him.

When Castle finally woke up, it took him a while to process what happened and where he was. As the cogs began to turn, the information that he was the father to Kate's child hit him like a brick wall.

"Why did you choose me?" Castle asked quietly, making Kate jump from the sudden noise in the quite room. Kate turned to him from her place on the couch and watched as he slowly sat himself up and walked over to her.

"What?" Kate asked, completely taken back.

"Why did you choose me?" He asked again, sitting down next to her.

"I didn't know it was you. They just give a photo. No name. By the time I'd looked though 50 donors, I was just interested in the baby photos. I had no idea it was you. If I did I..."

"You what Kate?" He cut her off, his tone almost rude.

"Rick I wouldn't have chosen you if I'd known. Our partnership and friendship means too much to me. I don't want anything to jeopardise that."

"Kate..." Castle tried.

"No, Castle." She told him, placing a hand on his chest. She looked over his shoulder and out the window into the bullpen. "Not here. I can't have this conversation here when anyone could walk in." She told him gently. Castle nodded in understanding. Kate gently squeezed his hand and sent him a sympathetic smile. "We'll continue this conversation when we got home." She clarified, standing up and walking back to her desk, leaving Castle to sit and ponder over the information.

Castle eventually stood up and, picking up his chair, walked back out to the bullpen and placed his chair back next to Kate's desk.

He was in a complete daze for the rest of the day.

When it finally came time for the pair to go home, Castle numbly collected his coat and phone, and walked to the elevator in complete silence.

"What the hell is wrong with him?" Esposito asked his partner.

"No clue. But I hope he's better tomorrow or else we might have to sit him out on this one."

Kate watched quietly as Castle fiddled with the front door, finally opening it. Kate, giving him his space, let him walk in in front of her, pushing the door shut behind her. Kate watched as Castle silently walked into his office and shut the door behind him.

Castle sat heavily in his desk chair as he thought over the day's events.

'I never dreamed that anything like this would ever happen.' He thought on a sigh, running his hand through his hair. Back then, he was just starting off as an Author and he was so low on cash he was desperate... 'On one hand it's not such a bad thing.' He sighed again, scrubbing his hands over his face. 'I just wanted this to go differently.'

"Castle?" Kate called quietly, opening his office door slowly.

"I just wish you had come to me first. If I'd've known that you wanted a baby..." Castle told her from his seat behind his desk. "Kate, if I'd've known, I would have moved heaven and earth to help you. If you had of asked me, I would have donated for you or even slept with you if that's what you wanted. And if you didn't want me to be in the baby's life, I would have accepted that." Kate stood in silence as she tried to absorb everything he was saying to her. "You're my best friend. My partner. And I love you Kate. I'd do anything for you." He told her, his eyes beginning to water at his words.

"I know you do Castle." She told him, rounding his desk, standing in front of him. "And I want you to be with me every step of the way." Castle smiled gently at her, standing up before cupping her cheek and slowly leaning in and placing a tender kiss on her forehead. When he pulled back, he rested his forehead against hers, eyes still closed. It was then that Kate slowly lifted her face until her mouth lightly touched his. Castle tensed at the unexpected touch before pulling her in closer and moving his lips with hers in a reverent and gentle kiss. When they finally pulled away, their breathing was slightly laboured while smiles slowly spread across their faces.

"We should have done that years ago." Castle chuckled. Kate pulled him back and placed a gentle peck on his lips, letting out a slight hum in agreement. "You know..." Castle smiled deviously, "If you still want a direct deposit, I would be more than happy to oblige."

"What good will that do?" Kate asked playfully, letting out a small burst of laughter.

"Well that way you can just tell people we slept together and save the hassle of explaining this." Kate's smile spread from ear to ear as she pulled him in by the lapels of his jacket and began kissing each other feverishly.
