Again, thank you to everyone who favourited/followed/reviewed and to those who gave suggestions for this fic.

I hope this chapter is clearer and easier to distinguish between the two.

Thanks for reading and I hope you enjoy it!

Edit: The Mr Peterson in this fic is in no way related to the Peterson's in season one episode two, Nanny McDead. It's just a coincidence.

Disclaimer: I don't own Castle or the characters.

Beckett woke up to the smell of coffee and breakfast cooking. She kept her eyes closed for as long as possible hoping that yesterday was just one big, very bad dream. But she knew it wasn't. She could already tell the bed she was in wasn't her own. And someone had made coffee and breakfast meaning she wasn't home alone like she usually was when she woke up.

She made her way downstairs to find Castle making coffee. She found herself glad that it was her Castle and not the other one.

"Morning," he said, as she sat down, both smiling as she accepted the cup of coffee and plate of food he offered her.

She looked behind her as she heard movement and the other Castle and Beckett stumbled out of Castle's room, obviously having smelt the coffee.

"Morning all" said the other Castle brightly, as he and the other Beckett entered the kitchen and accepted a cup of coffee and food as well.

"Coffee first, then me and Castle will head to the precinct to find out what we can about Mr Peterson," said the other Beckett, after she'd had a sip of coffee.

"I'm assuming you mean your Castle and not mine," said the past Beckett. When the future Beckett nodded, she continued, "we should have different names to avoid any confusion because this could get confusing very quickly."

Before either Castle could interject with crazy name suggestions the future Beckett replied with, "good idea," then she paused, trying to think of appropriate names for all of them. "Okay, how about we call you two Beckett and Castle, and we'll be Kate and Rick. How does that sound?"

Everyone agreed with the other Beckett, well now Kate.

They'd all just finished their coffee and breakfast when Kate's phone rang.

"Beckett," she answered, and then was quiet while she listened to whatever the person on the other end of the line was saying. "Ok, thanks Espo, we'll be there soon."

She hung up the phone and then addressed everyone in the kitchen, "Sorry, looks like we're going to have to put our plans of finding Mr Peterson on hold," and then she continued just addressing Rick, "we've got a body. We're going to meet the boys there."

"Castle and I can head to the precinct instead then, while you two are at the crime scene," said Beckett.

"Is that really such a good idea?" asked Kate, "what if someone sees you?"

"We're you guys, remember? And I'll wear a hat. We'll be in and out quickly, no one will know the difference," answered Beckett.

When Kate looked unsure, Beckett continued, "look, I know you're hesitant but we just really want to get home and the quickest way to do that is if we go to the precinct while you two are at the crime scene."

"Kate, we should let them go, they are us. As long as they don't talk to anyone everything should be fine. And not that I don't find your short hair sexy but you will need to wear a hat." said Rick, admiring the hair he remembered from when he first met Kate.

His comment earned him a hit on the arm and a "Castle!" from Kate.

"What? You don't like me hitting on your younger self?" Rick asked, a smile on his face. Kate could tell he was trying not to laugh.

Kate glared at him but she couldn't stop the small smile that broke across her face as her gaze softened. "Come on, we need to go, they'll be waiting for us," she said. She was about to go get dressed for work when she realised that Castle and Beckett would have no clothes to wear today. Instead of trying to explain to her younger self why she had a lot of clothes in Castle's room, she said she had some spare clothes that she could lend to Beckett. Rick said he could lend some to Castle too.

They both returned a few minutes later with a change of clothes for Castle and Beckett and Kate had found a hat that Beckett could wear to the precinct to cover her hair.

Not long later, everyone was dressed and ready to leave with Kate and Rick ready to go to the crime scene and Beckett and Castle ready to go to the precinct.

"Remember, don't talk to anyone while you're there," said Rick, as they left the loft. Beckett and Castle were going to wait 5 minutes to leave themselves as it would be a bit hard to explain why they suddenly both had twins if anyone saw them. They just hoped no one would notice two sets of them leaving the building.

As the boys and Lanie would be at the crime scene, the only person Kate and Rick had to worry about Beckett and Castle running into was Gates, she just hoped that that wouldn't happen.

Thanks for reading and don't forget to review and let me know what you thought.

If there are any scenes you want to see happen or any suggestions for future chapters review and let me know too :)

Updates won't always be this frequent just fyi but I will do my best and I'll continue writing as long as there are people that want to read it.
