Knocking away one of their hatchets with her blade, she felt the deflation beneath her feet, giving Jennifer a pretty good idea, as to where this would be going. The destroyed floor couldn't hold all of them, and so, it collapsed right underneath them. Making a yell, she descended with everybody else, nearly hitting her head on a table, just narrowly missing it. Groaning, although she had bruises, scratches, and cuts in some places, she carefully yet slowly got to her feet, helping Charlie get up. "Are you okay?", she asked, worried for her. 

"Is everybody okay?", groans and aches were heard from them. "...wipe out", Mikey piped up. Just before she could get an answer from the others, Jen caught sight of the same Japanese man she saw in the mirror; the same one who threw the knife at her, along with more of those men, standing behind him. Her question was the same as Charlie's. [i]'Is this guy the one pulling the strings?'[/i], she defensively put her sword in front of her; this time, standing a few inches, in front of her sister. If he could throw blades at Jen, and graze her, she didn't want to think about someone with this kind of skill to be placed in front of a beginner, like Charlie. She was lucky to have moved from the weapon's path, and avoid certain death. 

Just then, before anything could happen, the door to the store opened, only to reveal a very fit man, donning a hockey mask, and armed with a hockey stick. Panting, Jen blinked at the newcomer, he had to, at least, be around 25 to 30 years old - around April's age. [i]'Just who is this guy?'[/i], she thought; her question nearly the same as Leonardo's. Mikey's comment seemed to break some of the tension, but it didn't stop the bald man from sending his men upon them. At this rate, it was utter chaos in the shop, shortly until it started to catch fire. They were drastically overwhelmed, both because the growing flames and their assailants. It was like a nightmare. 

"Come on, we got to get out of here!", retreat seemed to be the only real option right now, and Leo was right. They had to leave, and find some other place to lay low. While the others played defense, April strove to find a way out. "Help me. There used to be a trapdoor here to the basement", she said, moving some things out of the way. The brothers, Jennifer, and the mystery man were pushing the men back, so to give April more time. It was strange, really. Who, in the human world, would come to their aid? No one, other than April, knew about their existence, unless...he bumped into one of the turtles, not too long ago? Did Raphael know him?
                   
"Get away, I'll take care of these guys", the man said, by the time April was able to reveal their way out, and crawl through, before she and the mutants were able to get Raph's body through. "You coming?", Leo asked the newcomer, once the girls were able to go through their only means of escape. "I'll cover you!", the turtle nodded, before going through himself. It was only about some time that the man followed after him, after taking time to hold them off. "Bye, guys, got to run!", and the trap door was shut, leaving the bald man no choice but to pull back, by the time sirens were heard. 

"Ninja, vanish!"
