"Did you want to try walking around for a bit more Mrs. Beckett?"

"Detective," Kate growled at the nurse. "And no, I want to get these babies out of me."

"I know, Detective Beckett, walking will help shift the babies into a good birthing position," the nurse smiled, maintaining her bedside composure.

"Yeah Kate, how about we try walking around again?" Castle smiled, trying to spread his calm manner to his stressed out wife.

Contractions crashing through her every five minutes, midwives barking orders, doctors explaining the risks of naturally birthing twins, it was all too much for Kate. All she wanted was to hold her babies in her arms. She wanted to hold them close to her and listen to the tiny heartbeats against her chest. Wanted to the present them to the family. Wanted to finally complete the family she always envisioned with her husband.

"Fine," she muttered, allowing herself to be supported by Castle's strong arms. Castle was amazed that six hours ago his wife's water had broken all over the floor of their favourite café whilst he hailed a cab. He had then paid a hefty tip to the poor worker required to clear it up. Six hours of waiting, having his hand squeezed to death, and watching his wife go through the agony of not being able to push

Pacing the room at an excruciatingly slow speed, waiting for their future to bloom, Kate made her way through another torturous contraction. She had been shot, tortured, drowned, and been in several other equally unpleasant situations and this may have hurt the most. The difference being there was a point to the pain. At the end of this perpetual walk of agony there would be two little boys who would no doubt bring them immeasurable joy.

Once seated upon the bed, knees scrunched as close to her chest as possible, Kate was given the okay to push at the next contraction. They were clutching hands, waiting for the pain to roll through again.

"I love you, Kate."

"Say something reassuring, Castle," Beckett choked out through her dry throat.

"I bet Grayson Alexander Castle is going to be the shy, sweet and sensitive one. On mother's day he'll come home from school with the sunflower he grew in class and a pretty little card with a poem he wrote. Jasper James Castle however will be a little clown. He will always be getting into trouble, nothing major of course, his mom's a cop right? Yeah, on mother's day Jasper will come in, nice and early, with a tray of his best attempt at breakfast food. Burnt toast and runny eggs but we won't care because he tried and we just love them so damn much."

The contraction came and the midwife gave Kate the all clear to push. Her face contorted with pain, Castle stopped his story telling to rub a hand down her back.

"Don't stop my story," Kate grunted.

"You know, I cannot wait to take them to Disneyland. I'll make them beg for it though. Grayson will pick up an increase in his chores and drop subtle hints. Little Mickey Mouse pictures drawn and stuck on the fridge. Jasper will bring out his Castle blue eyes and ask about it. I'd like to surprise them with it, say we're going to visit Alexis but we'll end up at the airport. I reckon the boys will be identical but Grayson will have your beautiful hazel eyes and I won't be able to refuse him anything. Jasper will have my blue eyes so naturally you will melt in them and do whatever he says."

"One last push, Mrs. Castle," the midwife smiled.

And with that massive push she felt a slight wave of pressure release and a tiny cry echoed through the room. Cord cut, whisked away for a quick clean and wrapped in a blanket the first baby was placed in Rick's arms. He untangled one hand so he could hold on tight to Kate as she delivered another earth shattering push.

The final push was just as Kate was ready to give up, exhausted, drenched in sweat, Beckett mustered every ounce of strength she had left and pushed and the second cry resonated through the room. She could no longer hold it in, tears coated her face. She reached out and held the wrinkled, pink child to her.

Castle noted the glow that surrounded Kate as she held their twins in her arms. He pulled out his phone and snapped a few shots of her grinning down at them. They decided to wait until the boys opened their eyes before assigning them names. They knew almost all newborns had blue eyes but they were sure that some clue to their designated identities was hidden in their eyes.

Sure enough after the family had come through and said their, "ooh's and aah's."

"Which one is Grayson?" Alexis had asked excitedly.

"We don't know yet. We're going to wait a bit, just until they open their eyes and we can see their personality a bit."

"That makes sense, I guess."

Sure enough, an hour later when only the four of them resided in the room, when the boys opened their eyes one of the boys, the lighter one weighing in at only 6lbs and 2 ounces, had Kate's hazel eyes.

"This one's Grayson," Kate whispered excitedly.

"He has your eyes," Castle choked.

"Castle? Are you? Are you crying?"

"What! No?" he lied. "It's just, seeing you with our babies, Jasper and Grayson, it just makes my allergies act up."

"We're a family," Kate whispered.

"That we are," Castle agreed. Each with a baby in their arms and their spare hands gripping at the others.

"So this one is Jasper?" Alexis asked, hours later in the loft.

"Uh, yes. He has your dad's eyes. Jasper has the Roger eyes and Grayson has the Beckett eyes," Beckett smiled wearily. "And you're sure you can take them until their food?"

"Of course, Katherine. You need sleep. You have had maybe an hour since these beautiful boys were born and you deserve rest. You both do, sleep," Martha smiled taking Grayson from Castle's arm and giving them a knowing look.

They then both collapsed on the bed, barely managing to kick off their shoes before falling into a heavy and exhausted sleep.
