A/N: I know what Castle did was HORRIBLE, and so I chose to do this… hoping that it would be both fun and realistic for Kate. If you disagree, don't hesitate to let me know. =)

The last chapter wasn't as good as I planned, but I think this chapter is what you guys like about the duo…

Beckett considered the possibility of freezing Castle out.

What he had done was far past, crossing the line, what he had done to her border-lined way past nasty and into the element of horror. The pranks were passing the fun phase now, and moving into unknown territory. Beckett had been mortified. But that being said, Beckett wasn't about to let Castle win the war. She was determined to fight back, and regain what dignity she had lost with his last prank. Beckett would get the last word in, even if it killed her.

She'd show him why many people feared Detective Kate Beckett.

She'd already chosen her tool of attack.

While she had been showing, she realized what had happened, and knew that Castle had been a part of it. As she washed her clothes in the toilet block sink, she recalled reading an article about sleepover pranks, and vaguely remembered hearing about dipping ones hand in warm water, causing them to pee themselves in their sleep.

While she scrubbed her brand-new, now tainted sleeping bag, payback reared its ugly head.

Beckett lay awake, still snuggled up closely to Castle, thinking about the camping trip. Castle had informed her it had been for a weekend, but as she looked back on the days, it occurred to her she had been there for four days. Neither had mentioned the time frame, and Beckett had told the Captain she was taking time off, until further notice. Where castle was concerned, it was always safe to say that he was unpredictable.

Castle stirred. "Mmm… Kate."

Beckett's eyes widened at the moan of her name passing Castle's lips. She remained silent.

"Kate…" he moaned again, a little louder this time.

Beckett felt something hard against her thigh, and her mouth dropped into an O shape, as she realized what was happening. Quickly, she turned her body around so that she was stomach to stomach with the man, which didn't seem to help the situation much.

"Castle!" she snapped pressing her hand to his chest. "WAKE UP!" she demanded.

"Kate… don't stop…" he mumbled.

Her face reddened at the image in her mind.

"RICK!" she whispered harshly.

His eyes snapped open, and he looked around, taking a moment for himself to realize where he was. His face reddened as he recognized what had happened. "Sorry," he muttered. "It's morning."

Beckett smiled. "Sure… do you always mumble my name in your sleep?" she teased clearly enjoying his discomfort.

"I didn't," he denied.

Beckett raised an eyebrow. "I heard you, Castle… Kate, don't stop, Kate…" she mocked.

Castle struggled to find the words to reply. "There are MANY Kate's in the world. You would think it would be vain of you to assume it was you I was dreaming of…"

"Yes," Beckett nodded. "Vain indeed."

Castle nodded.

Beckett slipped out of the sleeping bag. "I'll give you and junior a moment to yourself…" she smirked making her way to the tent exit. She turned back and smiled. "You were dreaming about me," she announced before slipping out of the tent.

Beckett was FAR from done paying him back, but the opportunity rose to settle the war, when Castle emerged from the tent half an hour later.

"Have fun?" she asked with a knowingly smile.

"That's not very nice," he mumbled slumping down in the fold-out chair beside her.

"I know," she nodded adopting a more serious tone. She handed him a plastic cup. "I was a bit mean this morning, here…" she offered.

"Apple juice!" his eyes widened in appreciation. "I love apple juice. Where did you get-"

"I stashed some in my bag. I have apple juice every morning before work," she explained.

Castle smiled with thanks and sipped on the cup, the liquid spilling down his throat.

Beckett lost it, as she snorted out a loud with a boisterous laugh.

Castle narrowed his eyes. "What did you do?" he demanded.

Beckett shrugged. "Only payback… the warm water prank… I had to put the drippings somewhere. Sorry Castle," she winked. "Sometimes I just have to have the last word. Drink up!" she urged.

Castle's face drained of color as he looked down into the cup. She didn't?

Castle threw the rest of the remaining liquid onto the ground, and covered his mouth with his hand as he made gagging noises. He looked at Beckett with wide eyes. He picked himself up off the chair and bolted towards the toilet block.

… … … …

"You win," he announced defeated as he returned to the tent area a while later, his face pale. He really looked unwell. "You played well."

Beckett beamed. "Why thank you," she nodded proudly.

He offered his hand to her. "Truce!"

She hesitated. "Yeah," she agreed shaking his hand. "Truce. Remember, you don't want to mess with me, Castle."

"No, ma'am," he groaned.

Beckett didn't want to spoil the fun and tell him that it really was apple juice!

A/N: Okay, come on! How brilliant was that? Hehehehe… it deserves a review, right?

This is the end of the pranks, sorry to say, but it's NOT quite the end of the story. I have some GREAT fluff scenes coming up, so hang in there. It's worth it. I PROMISE! =)
