Cat was meditating on the armchair in the living room, legs crossed and eyes closed.

Mikey and Don were sleeping, one with a magazine over his eyes, and the other hugging comic books and junk food to his chest.

She heard the front door open, but didn't need to open her eyes to see who it was.

'…Leo…'

A smile flitted across her features, but she reined it in.

She heard him enter Splinter's room, and knew he was going to check in with him first.

She knew Raph peeked in, hearing the conversation, when both came out. Raph rudely woke both his sleeping brothers, and Cat opened her eyes.

"It's been so long, Leo."

She smiled brightly.

"I missed you."

He smiled as Mikey and Don hugged him.

"I missed you guys, too."

She stood up, and lifted both younger brothers off almost effortlessly.

"My turn, bro's." She joked, not realizing the shock that flitted across all their faces.

She'd hardly tried, and lifted two turtles, each in one hand, off the ground.

She put them down gently, and hugged Leo, lifting him easily off the ground.

"What took so long? Get on the wrong plane back to New York?" Cat joked.

"…Kind of…"

She pulled back, looking a bit confused, but he changed the subject.

"You've really grown, Cat…"

She smiled slightly.

"Yep!"

'She looks like she's an adult…'

He shook his head slightly.

"I was hoping we could go on training topside. What about it?"

They nodded, and Cat went to the door, a jump in her step.

"Let's go then, slowpokes!"

They were soon topside, across from a building in construction.

Cat hung upside-down on the metal structure on the roof, smiling.

"So, what first?"

"I've heard teamwork is lacking, so we're gonna have to work on it."

Cat sighed.

"Yeah…so…"

She perked, eyes zeroing in on the building across from them.

"…Foot ninja…and something else…"

She flipped onto her feet, looking over the edge.

"…Some kind of creature…"

"Then let's go get 'em!"

She sighed as Raph used a crane to get across, Mikey and Don following.

Cat just shrugged slightly at Leo, following her other brothers with the natural balance of the feline her nickname represented.

Once on the building, she looked in mild surprise at the large monster, Foot ninja trying to subdue it.

"…You know, it's gonna run out of bodies soon…" Don noted, ducking as a Foot ninja flew over his head.

"I ain't getting in the middle of THAT…" Cat muttered.

"Yeah. I say we sit back and enjoy the show." Mikey agreed, sitting back.

But Raph ran in, and Cat wasn't about to let him go in alone.

She ran in without pulling out her blades, and grabbed the monster around the neck when it lunged at her.

She choked the monster in a headlock as the Foot ninja retreated.

"This isn't so hard." She noted lightly, when a large clawed hand grabbed her around the waist.

Her foot shot out, hitting a pressure point, and she was dropped, landing on all fours like a cat.

She jumped back in, getting it in the chest as her brothers distracted it well enough.

It brought them down through the floors, and they landed in a heap.

"…I'm gonna get that overgrown fur ball…"

Cat sat up as the monster roared at her brother.

"Mikey, got anymore bright ideas?"

"Just this one…"

The two youngest turtles shared a glance.

"AHHHHHHHHHHHHHHHHHH!!!!"

Cat rushed forward, hitting the monster away with a spinning kick as the ceiling collapsed on her brothers.

She hid immediately in the shadows as she heard someone come, and her eyes widened in surprise as four stone statues came and subdued the monster easily.

'…Whoa…'

"Someone's here…"

She tensed, seeing as the diamond around her neck caught the light.

'Either Master Splinter is trying to kill me, which I doubt, or this thing hates me…'

She pulled out her blades as she lowered herself into a crouch, ready for anything.

After all, these were frickin' stone statues, for God's sake!

A stone blade, but she jumped before it made contact.

She jumped down, pulling back her fist, and punched the ground.

It splintered and shattered, sending rock and debris at the statues.

The largest charged at her like a bull, and she smirked.

'Too easy…'

She dodged his swings easily, moving lightly on her feet, and did a hurricane kick that sent him into a wall.

Two more charged at her, but she just held up her fists.

"Nice try…"

She flicked them in the foreheads with her pointer fingers, sending them into walls as well.

"But not good enough…"

She heard sirens, and cursed.

'Damn cops and their bad timing…'

She went to the mound of rubble that covered her brothers, and stuck a hand in, grabbing one brother and pulling him out.

First Mikey, then Don.

After pulling out the last two, she smacked them upside the head lightly.

"Let's go! The police are almost here!"

That snapped everyone out of it, and they all ran to the manhole they'd used to get topside.

Cat saw Raph stop, watching a strange truck drive off.

"Raphie, move your shell!!" She yelled, ignoring Leo's calls to move.

She grabbed the red-banded turtle's hand, pulling him after her.

She didn't leave anyone behind.

That was her way, her Nindo.

Once safely in the sewers, Cat caught Mikey looking up.

"Yes!! The turtles are BACK!! I give us a 10 for style, and 8 for skill…"

Cat sighed, smacking her forehead as she heard a part of the building fall.

"…And a 2 for stealth…"
