Procyon's Tears & guest, thank you for your reviews! Inspired me to post the next chapter. (: was kind of on a writer's block with this one.\

Enjoy!

Bree sat on a rooftop, watching where she had just exited the sewers to make sure no one was following her.

She appreciated these four.. Creatures help, but she didn't want to risk involving them in her fight.

Slowly getting to her feet, Bree winced as she put weight on her bad leg. She was actually pretty grateful that it was wrapped and treated, otherwise, she wouldn't have been able to escape.

Even so, she figured she'd see those four again.

Donatello yawned as he surveyed the computer screen. There had been no reports of that girl on the news or any website he searched on in the past few days. In fact, there was no reports of an injured person found either - she must have been pretty good at hiding herself, despite being injured.

"Hey Donnnn, whatcha doing?" Mikey came over and popped his head in front of the screen.

The turtle slapped his brother away. "Mikey, cut it out."

"Awww." Mikey ducked and came to Don's other side. "But I'm bored and this looks more interesting than the news right now."

Shaking his head, the purple turtle sighed. "I'm looking for missing reports on that girl we had saved yesterday. There's nothing here."

"Well if you're so worried about her, maybe we should go look." Mikey suggested.

"Don't worry, bro." Raph, who was practicing with his punching bag, cut in. "She's probably at home with her family or something."

"Yeah, you're probably right." Don switched off the monitor of the computer to avoid Mikey being in his face anymore.

With a final series of punches, Raph knocked the dummy over and leaped up to land next to his brothers. "Hey, anyone up for a surface run?" He pointed a finger upwards.

"YES YES YES!" Mikey ran over, grabbing his brother by the arm and racing to the elevator.

Leo and Donnie exchanged glances and then shrugged. It has been pretty quiet lately, and they could use the air. Even Leo felt they could benefit from going topside.

The four turtles raced across the rooftops, yelling out whoops of joy and laughing as they leaped. Hidden in an abandoned building where she had escaped the sewers, Bree could hear them calling out to each other as they ran.

Pondering her movements for a minute, the girl sighed and tucked a piece of blond hair behind one ear. She had put her hair back into it's usual braid, and attempted to clean herself up by borrowing clothes from a nearby clothesline. But she didn't ditch her cloak, as it was made of materials only the most gifted in her world could find and manipulate. Giving it up would be like removing a piece of her, one of the only remains of her home.

Bree pulled up her hood and exited her temporary home, grabbing the bag she always carried just in case. Leaping out of the window, she caught the edge of the roof and pulled herself up in a spinning leap, landing gracefully on the roof.

She needed to know if she could trust these four creatures, so she did the only thing she could think of: She followed them.

The brothers had stopped on a rooftop overlooking the lake to rest. The city tonight was beautiful, and the moonlight gave off more light than usual as its glow hit the turtles' masks.

"It'd be a nice night for a swim right about now." Mikey stared at the water longingly.

"That's a bad idea." Leo announced immediately without a thought.

"Awww, why? It's not like anyone would see us. It's after midnight, nobody's up now."

"If I wanted to swim I would've stayed back at the lair, the pool we have there is actually deep." Don put in.

Suddenly, a knife whizzed onto the rooftop next to Mikey. "AHHH." The orange turtle yelled, jumping out of the way.

A cloaked figure stood on the rooftop opposite them, watching. With a running leap, Bree leaped across the opening and threw another knife, this time towards Raph.

"WHOA." Raph dodged and withdrew his sai from his belt. "Who do you think you are?" He lunged.

Without a blink, Bree drew another knife from her belt and threw it at Leo, who jumped away just in time.

She expertly dodged Raph's attacks, ducking and twisting in the air to avoid the sharp blades. Drawing yet another knife from her belt, she aimed it at Don, who yelped and couldn't react in time. It hit his mask and pinned him to the wall behind him.

Mikey leapt from behind and swung at Bree with his nun-chucks. She dodged, letting him wrap one around another one of her knives, using the knife to pull the weapon and holder towards her. She pinned him to the floor and withdrew two knives, pinning him by his belt to the ground. "HEY!" The turtle cried as he struggled to break free.

Leo ran behind her and unsheathed a sword. She reacted and leaped away, landing delicately on one hand and using it to push her up behind a charging Raph. Grabbing a knife from the ground, she attached a metal cuff-like piece of metal to the end. Raph, turning around quickly, threw a sai at the girl, who dodged and threw her own knife towards him. It hit his wrist, throwing him backwards towards the ground. The knife end lodged into the ground, leaving Raph pinned as well. "What the shell?" The turtle cried, trying to struggle away.

With most of her knives used on the other turtles, Bree withdrew her remaining blade that was resting on her belt, a thin katana with an intricate hilt, and faced Leo.

The turtle ran forward without hesitation, and Bree met his attacks with her own. Leo lunged his blade forward and Bree blocked, the two entering a sword battle. Bree swung, ducked, dodged, leaped, jumped, almost like she was a ninja herself. But her fighting style was different, something far more intricate than their own. Donatello, still pinned to the wall, slipped off his mask and rolled away. He tugged the knife from the wall and threw it towards the girl, trying to target her cloak.

The knife hit and she was momentarily slowed down, her cloak pinned to the ground. Gasping, Bree dropped her sword and tugged at the cloak, trying to dislodge her own knife. As she did this, Leo took the opportunity to knock her to the ground with a sweep of his sword, and pointing it at her throat.

Bree screamed and her hood fell off, revealing her face.

"Wait! That's the girl we helped the other day." Don immediately recognized her, running over. The other two turtles had finally freed themselves from the knives, tossing them away.

Bree said nothing, staring up at Leo as her identity had been revealed. He and his brothers had won.

Leo hesitated and lowered his blade slightly. "Okay, talk." The leader said. "Who are you? Why did you attack us?"

"Why did you leave us after we helped you?" Mikey and Raph walked over, surrounding her.

"Because." Bree said simply. "I need your help, and I had to decide if you were trustworthy or not. You spared my life despite my attempts to injure you, which showed me you understood what true honor is."

"So you attacked us? Pinned us down with those knives of yours?" Raph tossed a knife to her feet.

"You wouldn't have heard me out if I hadn't attacked."

"But you were in our lair, what's so important that you had to try to kill us to get our attention?" Don exclaimed.

"I didn't try to hurt you." The girl scoffed. "If I wanted to kill you, you'd be dead by now."

"Well, Lady, you're kinda beat now. So spill." The red banded turtle angrily yelled, putting his sais back into his belt.

Looking up at Leo standing over her, surrounded by his brothers, Bree sighed.

"I'm not from your world. In order to get back to my own, I need your help, and I need you to help me defeat these usrlin that keep trying to kill me. I can't do it on my own." She finally let out after a period of silence.

Leaning on his bow staff, Donatello studied her. "You mean those weird shadow creatures that attacked us the other day?"

"Yes. They're called usrlin ." Bree sat up as Leo lowered his sword further, still watching her closely. She picked up her knife. "They're creatures of the undead, created by dark magic with shadow and bone. One of those darts they shoot? It can kill you."

"But you were shot with one." Raph pointed out. "How come you aren't dead?"

"That's why I need your help." Bree whispered. "The dart is fatal to those who do not know how to thwart it's poison. Since they're here in your world now, you're doomed if they try to attack you or any of the people in this city. Without me, your world will soon be overrun by these monsters."

The four brothers exchanged uneasy glances.

"Okay." Leo sheathed his sword and offered her a hand. "We'll help you. But you have to tell us everything."

"Including where you learned to fight like that." Raph grumbled.

"Fine." Bree grabbed Leo's hand and let him pull her to her feet. "But you're not going to like it."
