A/N: The epilogue:D enjoy

The bullpen was vacant. The entire precinct had been emptied of all its workers. One dim light hung high in the precinct gym. A large blue mat covered the floor. Standing on that mat was a light-haired detective. He spun on the spot, looking for signs of a woman in heels, a buff man in a polo shirt, a man in a button-down, or a kid in a private school uniform.

A noise came from behind him. The light barely lit up the large room. Kevin spun around to see a solo punching bag sway. In his hand, he held a Lightsaber. He pressed a button and the plastic shot out of the handle. He pressed another button and the plastic sword glowed bright green.

"Show your face, coward," Kevin snarled, using his most intimidating voice.

"I'm no coward," Esposito said as he stepped out of the shadows. He pressed the buttons on his Lightsaber. It glowed red.

"I'll take you down."

"I'm afraid you won't," Rick said as he emerged from the men's locker room, newly lit saber aloft.

"Two against one? Hardly a fair fight."

"Not too worry. We've got your back," Kate said as she and Sean Jr. appeared behind him.

"Time out!" Esposito called. "You got the kid, too? That's not cool."

"Oh, didn't we mention that? Sean came by today. He's the reason we enough Lightsabers," Kate explained, putting her arm around his shoulders.

"Hold on! Sorry I'm late guys," a sassy voice called from the hallway. Lanie swung the gym door open.

"Someone held me up. They told me to give Kate some news, but I think this is news we could all enjoy." Everyone turned off their Lightsabers and stared at her through her dramatic pause.

"Just tell us, Drama Queen," Kate said with a laugh.

"Kappa was completely wrong. It's not his baby."

Everyone let out small cheers and took turns hugging or shaking hands with Sean. Lanie then explained that the test results had been mailed to Sean Sr. He wouldn't have to worry anymore.

"I say we celebrate," Castle said.

"How?" Kate asked, quirking an eyebrow.

"Lightsaber battle."

"My gosh, Castle, you are such a loser," she sighed.

"Where's my 'Star Wars' nerd sword thing?" Lanie asked.

"Lightsaber!" Castle corrected with a whine.

"Yeah, that."

"Here."

Sean walked to a corner and opened his book bag. He withdrew a Lightsaber and handed it over. Lanie turned it around and around in her hands, deciphering the contraption. Sean then explained how it works. As soon as Lanie was ready, they resumed their scene. It was now Lanie, Rick, and Javier against Kevin, Sean, and Beckett.

They proceeded to jump, roll, spin, and run around the room, waving the Lightsabers around. Their battle lasted for over an hour. They all agreed that winner got to pick the place to get ice cream. Kate's team won after an exasperated Lanie threw her hands into the air and shouted, "I surrender! I'm done!"

Kate let Sean decide the ice cream place. They called up Mr. Zimmerman and invited him along, too. They met at a place three blocks down from the precinct. They all ate and chatted cheerfully. Kate reached into her pocket and pulled out her phone. She sent Rick a text.

Wanna come over after this?

For a nice chat and a cup of tea?

I had something else in mind...but if you just want to chat...

Castle's eyebrows shot up to his hair line.

Actually, let's go with your plans.

But tea sounds really good now that you mention it...

Well, what were your original plans?

It certainly didn't involve tea. Actually...maybe iced tea

Iced tea?

I can show you a magic trick. I do this thing with ice cubes...

You tease.

My place...10:00

Okay.
