Disclaimer: I don't own X-Men, but I sure as heck own Kat/Acidwash (oh, yeah and I don't own Lacreymosa either, however it's really spelled).

I'm back with vengeance! Ok, not really, I've just got another chapter for you all. Hopefully, a better chapter than my last two. I don't have too much to say, other than thanking you all for the reviewing you've been doing for me, and just wanted to say sorry about the whole paragraphing thing. I will start separating the dialog from the rest of the story, the best that I can. I'm also sorry if you can't read this very well, I don't really know what to do about that. Every time I try to space things, it always gets all messed up like. Well, with that said, here's the next chapter. Enjoy...

-Chapter 5: Dangerously Corrosive

"Alright, alright people, settle down. Now let's get right to the lab. You only have a week, so we might as well get right to business." The teacher yelled as the bell rang and the last few stragglers slipped into class. "First take the liquid chemicals on your desks and pour them into the test tube in front of you." Class droned. Kat looked over to see Kurt with his head propped up on his arm, looking somewhat unconscious. She could take no more.

"Now proceed to take the powdered mixture and-"

"Hey, watch this," she said with a devious grin as she began to pull off one of her protective gloves.

"What are you doing?" asked Kurt, quickly perking up, seeing that she was probably going to do something to get them in trouble.

"Just watch," she said still grinning. After she had one glove off she held her bare index finger directly over the test tube, as a single drop of a greenish colored liquid formed from her bright green nail, and fell into the chemicals below. Almost instantly the test tube bubbled and overflowed with a blackish-green substance. The test tube broke and the bubbling liquid started to eat away at the countertop of the desk.

"OH MY GOD!" shouted the teacher as she ran over to the table, seeing the small biohazard that had formed. "Quick some one go get the janitor!" A most of the kids laughed, two of them being Kurt and Kat. But after the teacher had finally regained control of the class, Kurt and Kat stopped laughing.

"I would like an explanation of what just happened!" shouted the teacher after having both accused students march to the front of the room. She glared at them from behind her pair of glasses. Kurt looked nervously up at her but Kat knew it was time to go on stage.

"We were just fallowing your directions. We poured the powdered chemicals into the tube just as you said when it started to bubble." She said, giving her best innocent look, figuring if she needed to, she could easily whip up a few tears too. The teacher's face softened. "Maybe we got the wrong kit by accident." She said with a weak shrug.
~*~*~ Kat watched in amusement as the choir teacher barked at the class like a small dog on a leash. Lachrymose was a hard enough song to sing without the constant roar of Ms. Jarron yelling at them about taking a breath too soon. Of coarse standing the whole period on crowded risers in the auditorium for a class that she hated didn't make things any easier. Kat hadn't gotten a choice or not in the matter of taking choir, it was just manually put there for her enjoyment. She often mouthed the words instead of actually singing them herself because of not only her strong dislike for the teacher, but inability to sing. But the worst part of the class, was that it was boring too. Just standing there making unnecessary noise was right next to math and biology. The only amusement she could ever drum up out of the situation, was watching to distorted look on people's faces as the happened to pass the aud.'s open doors. The combine volume of the choir and their trouble hitting the exact notes always caused the passer-buyers to stop and stare for a moment, until they remembered that they actually had some where to go. So far she had counted 12 people stop and stare.

"COME ON, THERE IS NO BREAK THERE!" screamed Ms. Jarron, practically falling over. Kat snickered lightly at the twitching teacher, only to look up to see the thirteenth person stop to stare. She couldn't believe it. She was safe nowhere. There in the door way stood Pietro, happily grinning at the distressed choir. Kat quickly turned away. Maybe he hadn't seen her. Maybe he didn't know she was there. As she turned she saw several other girls giggle and wave to Pietro who had now taken a seat in the very back of the auditorium. It hadn't occurred to her that possibly, hopefully, Pietro had come to flirt with his numerous little liaisons. But what ever he was truly hanging around for, he managed to stay until the end of class.

"That was lovely. So, are you a soprano or an alto?" Pietro asked in his usual cocky tone as he walked along side Kat.

"For your information, I don't even bother singing, but supposedly, I'm an alto. What do I owe the pleasure of your presence in the auditorium?" she asked with a smile. "Or am I to believe that it was somebody else you were watching?"

Pietro's face perked up at Kat's sarcasm. "Oh, don't worry, you don't owe me that much, and no, though I was greatly tempted to go astray, I was too shocked that YOU would be in a thing like chorus to pay attention to any one else." He said with great satisfaction.

"What you don't think I can sing?"

"No, I just don't see you as the vocal type."

"Well, you're probably right. I mean I do hate chorus with a passion. It's not like I enjoy acting like an idiot every day on those godforsaken risers." She hadn't realized that she had just agreed with him until after the words were out of her mouth, and then she quickly regretted it.

"What? Excuse me? Did I hear you correctly? Did you just say I was right? It's about time that you started recognizing my genius." Pietro said, a broad sneer glowing across his face.

"Why don't you come back down to earth, and stop being so cocky. I didn't mean anything by it, so just breathe." Kat walked a little faster through the hall, even though she knew it wouldn't get him to go away.

"Fine but I'm glad your finally catching on." She glared coldly at him and he decided to move on with the subject. "If you hate it so much, than why don't you just skip? I do it all the time."

"Because they take attendance." She replied flatly. "And I have no where to go while 'skipping'."

"I do. Like I said, I could get you out of it, no problem. So what do ya say, I mean you're not scared or anything are ya?" he questioned in a taunting voice.

"Hey, challenges might work for you, but I'd like to think I'm a little stronger than that." She said nattily. Then she thought for a moment. The worst thing to happen to her was detention. "Maybe it wouldn't be so bad." She said thinking out loud. Pietro just continued to smile. This was perfect and if the professor, who would undoubtedly find out and put her through some 'light punishment', all would go as planned. "Good, just be ready tomorrow."
~*~*~ Kat felt more stupid than usual in choir, as she watched the hall like a hawk, waiting for Pietro to appear around in the doorway. Class had just started and she was afraid that he wasn't going to actually show up.

"I'm looking for Kat Pierce." Said a voice from the back of the auditorium. Kat smiled. 'So he's not as big a schemer as I thought', she thought to her self.

"What?" said the teacher as she turned to face the interruption.

"She's needed in the office." Pietro acted as if had been doing this all day.

"Oh, ok, whatever, go." Ms. Jarron replied not even looking up from her sheet music. Kat proudly walked down from the risers, before remembering to act like she had no idea what was going on.

"So where's exactly are you dragging me off to?" Kat asked skeptically.

"You'll see. I must say though, I give you more credit than the rest of those X-losers. You actually have guts." Pietro would have never said anything like that, if he hadn't needed her to trust him. Complements weren't his thing. He was better at insulting or teasing, not giving people an easy time. It was just another defense in others people's eyes, but Pietro just blamed it on his awful nature. Kat looked at him somewhat confused, and even a bit flattered but decided to shake it off and just fallow him. When they managed to make it out the front door and started down the street toward the busy part of town, was when she figured that she should say something.

"Ok, it was one thing to skip class, but to leave school?" Kat said a hint of nervousness in her voice.

"C'mon, it's not that far and let me once again remind you that I would not take time out of MY day to do this for anyone." He said dragging her from building to building. He was getting more and more impatient as they went along, due to never having to move around this slow before. It wasn't his thing. "Pick up the pace would ya. I'm getting old here."

"Oh yes, your company is greatly appreciated." She muttered. Pietro just smiled.
~*~*~ After a short walk from the school, they arrived at what looked like an old abandoned warehouse.

"So this is your amazing hide out huh? Kinda has that homie-bat-cave feel to it." Kat remarked with a voice normally used for an after school special. She dusted off an old crate and sat down. Pietro paced a bit just because he didn't like to sit if he could help it. "What? It's a good place to come and think."

"You mean to tell me you think?" Kat looked to Pietro and smirked, but he didn't smile back. "What?"

Pietro knew that now was his time to work his charm to the fullest, but not the sort of charm that comes with flirting, more like a serious intellectual charm. He gave her most meaningful eyes and managed to sit down.

"I used to come here to think about different stuff, like my family and the whole 'different' sides thing."

She could tell he was really being serious. "Your family?" she asked. She had never really thought about his or anyone else's family. Never truly having one her self, it just wasn't something that had crossed her mind before.

"Yeah, it's pretty messed up, with my adopted family and my real father. What about you?"

She just looked at him for a moment thinking. "Never really had one. My parents died when I was young I guess. I lived on the streets for most of my life. There was this guy that I guess you could say took care of me. He was a mutant too, but he wasn't the most nurturing guy ever. He's dead now, so that's how I ended up here." Kat said realizing that this had been the first time that she had brought up her past since she had come to Bayville.

Pietro just looked at her. 'Good' he thought to himself 'She trusts me". They sat in silence for a minute or two before Kat remembered that school was still going on somewhere and that they should probably head back.

"What time is it? We should go back." But the truth was, was that she didn't want to go back. She liked the comforting, dark, musty, atmosphere of the creaky old building.

"I guess." Pietro didn't care what they did at this point. Everything was going better than he had expected. He would end up surprising the X- Men, and most importantly he would prove to his father that he was capable of more than just what ever the brotherhood told him to do. As they left the building, Pietro couldn't help but smile at the thought that he was a very talented actor indeed.

SN: My god, I'm sorry that took so long. I had horrible writer's block, my computer crashed twice and I was on vacation for two weeks. I apologize, really I do. Oh, and just for fun, I've been trying to match songs with the characters of X-Men. Maybe not all the characters but some of them anyway. So far I thought that "I Hate Everything About You" by Three Days Grace was perfect for Pietro. If you have any ideas, let me know.
