A/N: Hello again!

Two chapters in one day? Dude I'm on a roll here!

Okay, so a few of you wanted a drabble on No Love Is Greater, and you mentioned something focusing on Leo and Karai's relationship. So, because I love that concept so much, I decided to go ahead and write it!

Partners in Crime

"Again, again, again! Do it again, Uncle Tiger Claw!"

"Yeah, daddy! Please do it again! Please!"

With an exasperated roll of his eyes, though he couldn't prevent the smile that spread across his feline features as he gazed down at the two children bouncing on their toes below him with their arms outstretched, Tiger Claw sighed. "Very well," he relented at last, "I will do it one last time. But, you must promise me that you will do as I asked and go to bed, Wakarimasu ka?"

"Wakarimashita!" Leonardo and Karai chanted in unison, the eight year old turtle and the nine year old girl both beaming brighter than the sun at their success as Tiger Claw bent down and picked them both up, one in each arm, and held them close to his chest. Giggling with excitement, they clung onto his shirt with all their might as he looked to them both.

"Ready?" he asked with a grin.

"Ready!" they chimed.

Without further ado, Tiger Claw activated his jet pack. Within moments, his feet had left the ground and he and the two children he held in his arms were soaring high into the air, bursting through the trees that surrounded their forest home as they flew. Leo and Karai screeched and laughed as they hovered high above the treetops, their grip on Tiger Claw's shirt tightening both out of the possible fear of falling and out of the excitement that threatened to burst from their bouncing little bodies.

"We're up so high!" Karai cried elatedly in his right arm. "Ooh, Uncle Tiger Claw, go upside-down again!"

On his left, Leo nodded rapidly in agreement. "Yeah! Go upside-down, dad!" he repeated.

Rolling his eyes once more as he chuckled, Tiger Claw tightened his grip around the two children, and took them utterly by surprise as he suddenly flipped himself backwards, hovering upside-down in mid-air as they shrieked. Their little feet dangled down from above as kicked their legs back and forth, their faces nearly red due to their screaming laughter and the blood rushing up to their heads. Tiger Claw himself was not phased so much by the shift in gravity; it was their combined high-pitched screaming that bothered him the most as he flattened his ears as much as he could to his head in an attempt to stifle the noise.

Once he deemed they'd had enough of that, he righted himself again as he slowly lowered them back to solid ground. Once his feet touched the grass, he allowed them to stand on their own and watched with a chuckle as they stumbled about dizzily, still giggling as they wavered backwards and forwards.

"T-that was craaaaazyyyy!" Karai tittered, before she bumped into Leo, sending them both tumbling to the grass with another burst of laughter.

Tiger Claw shook his head for the umpteenth time as he folded his arms over his chest. It was due to his master, Shredder, being away on important business that he had left his daughter to stay with him and Leonardo until he returned, for she had no other babysitter to look after her. This particular request had been a bit of a shock to the mutant tiger, for he had never been asked to do fulfill such a task before. Leo, on the other hand, had been ecstatic upon hearing that his new friend was coming to stay for a few days. Karai had been no different, and the two had practically tackled each other to the ground upon her arrival that morning after one of Shredder's personal servants had dropped her off.

Throughout the first few hours of the day, the young human girl had been well-behaved and polite in his presence. But that was only until her shyness melted away. After that, she and Leonardo had quickly become 'partners in crime' as it were, constantly pestering Tiger Claw and getting into shenanigans that had ended up with them in the bath more than twice already. It was only after promising them that he would let them fly with him on his Jet Pack before bedtime that they eventually calmed down, but now he feared that they would be too giddy with adrenaline to go to sleep.

Children were odd little things sometimes.

Returning his attention to the two of them as they lay sprawled out on the grass, Tiger Claw put his hands on his hips. "Now then, are you two ready to go to sleep?" he probed.

To his relief, they both nodded. "Hai!" they piped up.

Tiger Claw nodded. "Very good. Let's get inside and get you dressed for bed then, shall we?"

"We can't," Karai panted.

"We're too tired. We can't move, Sensei," Leo whined dramatically with a hand over his forehead.

Raising a brow, Tiger Claw feigned annoyance as he shook his head. "Well, that most certainly will not do," he said. And then without warning, he bent down and grabbed one of each of their legs, lifting them off the ground with ease as they screamed yet again in surprise, laughing breathlessly as they dangled upside-down once again in his grip. Unable to stop laughing himself, Tiger Claw walked inside the house and made his way to the spare bedroom that Leo and Karai shared, where he then dropped them on top of the futons.

They laughed and rolled across the futon for a moment longer, before they calmed down enough to get up and get prepared for bed. Tiger Claw left the room, allowing the two of them some privacy as he went into the bathroom to wet a cloth to wash their faces with. When he returned, however, it appeared that Karai had gotten her head stuck whilst trying to pull her pajama shirt on, and Leo was attempting to help her by pulling the bottom of the shirt down with all his might.

Rolling his eyes yet again, it took everything within his power to prevent himself from laughing out loud. "Kids," he sighed as he stepped inside the room to help the poor trapped child.

It was in the late hours of the night when Tiger Claw had been awakened from his sleep by the sound of a door sliding open, followed by light footsteps as they shuffled towards the kitchen. At first, as he cracked his eyes open and stared exasperatedly up at the ceiling, he'd been somewhat annoyed at the fact that one of them, or both of them, had not yet fallen asleep after all this time. But his annoyance quickly vanished at the sound of a sniffle as the lights flicked on in the kitchen, and the distinct smell of salt that filled his nose.

His brows furrowing, he sniffed again.

It was Leonardo.

Tugging his blanket off as he got out of bed, Tiger Claw quietly slid the door of his room open and poked his head out to find that it was indeed Leonardo, sitting down on the floor in the far corner of the room with his knees drawn into him and his crossed arms covering his face as he quietly cried.

Tiger Claw frowned deeply. It had been months since Leonardo had been taken out on his first killing mission, and only weeks since the talk that had been the start of his long road to acceptance and recovery. Of course he would still have nightmares. After all, it had taken himself just as long to grow adjusted to the life he now led.

He was about to step out and comfort his distraught son, but the door of the spare bedroom slid open, and he quickly ducked back inside his room as Karai hopped out.

Her confused amber eyes darted around the darkness of the house, until she spotted the light illuminating from the kitchen and tip-toed her way across. When she spotted Leo sitting there alone and crying, her eyes widened. "Leo?" she whispered.

Taken by surprise, Leo gasped as his head snapped up from his arms. He quickly wiped the tears from his eyes with the back of his hand, though he knew she'd already seen them, and looked up at her. "…h-hey Karai," he mumbled miserably. "Did I wake you up? I'm sorry."

Karai shook her head, her short black hair swishing from side. "No, you didn't. I just turned over and you weren't there," she said as she moved to sit next to him on the wooden floor, crossing her legs and tilting her head as she regarded his sad face. "Why are you crying?" she asked.

Sniffling, Leo looked down at his knees as more tears fell. "…I…I killed somebody, Karai," he whispered shakily, his shoulders trembling as he fought back a sob. "Your dad made me kill somebody for a mission...it was horrible, Karai. Tiger Claw said that he'd help me, a-and I believe him, but…I still get nightmares all the time. I d-don't wanna kill anyone else anymore!" he whimpered, covering his face with his hands as he began to cry.

Karai watched him with wide eyes brimming with her own tears, before she shuffled closer to his side and wrapped her arms around him, holding him close. "...It's okay, Leo," she soothed, stroking the top of his head. "…I killed people too…"

At that, Leo lifted his head again to gawk at her with wide, disbelieving eyes. "…r-really?" he stammered.

Karai nodded sadly, turning her head away as she shivered. "…yeah. My dad says that if you're gonna be a rue ninja, you gotta be prepared to take a life for the honor of your clan. I don't know if I believe it, and I don't like it either…I hate killing people. It's wrong, and it's really scary. I have nightmares all the time too, but I can't always go to my dad for everything that scares me. I gotta be tougher than that, or at least that's what he says…"

Smiling softly, she then turned back to Leo. "But now I have you to talk to whenever I'm scared. And you always have me, too! Right?"

Leo blinked at her once, before he sniffed and wiped away his tears again. Once they were gone, he returned her smile as he nodded, and then wrapped his arms around her in a tight hug. "Right!" he said, nuzzling his cheek against hers as she threw her arms around him again.

Peering through the doors of his bedroom, Tiger Claw smiled warmly at the scene before him. He had never seen such moral wisdom from the young girl before, for she was almost always bouncing with pure, unstable energy whenever she and Leo were together. But now watching as she brought him comfort, expressed her profound feelings…

Perhaps she was not as much of a trouble maker as he'd first thought.

As they pulled away from each other, Karai's mouth shaped into a wicked grin. "So, do you wanna go and draw on Tiger Claw's face whilst he's sleeping?" she whispered with a cackle, which Leo soon echoed as he nodded his head.

Tiger Claw's face fell. Well, she was wiser than she seemed, but the two of them together were undoubtedly still a pair of young, trouble-making 'partners in crime'. He wondered – and prayed – if they would ever grow out of it as they grew older.

He doubted that very much…
