AN: This is a bit of a spoiler, but I'm warning you now that this is probably the most disturbing chapter of the fic. Kim is going to personally see video footage of the tweebs' abuse on Mr. Gray's phone, and while it's both short and non-graphic—I did want to keep the fic's T rating—the very nature of it is both highly upsetting and a trigger for anyone who's been abused in real life. So even if I haven't already scared you off with the fic's basic plot, reader discretion for this chapter is STRONGLY advised.

The ride to Middleton Middle School from the police station was only about twenty minutes, but to Kim it may as well have been hours. All she could think about was what her brothers had been through and how badly she wanted to make sure Mr. Gray paid for it. She had been on countless missions to stop bad guys before, of course, but this one was in a class by itself. Kim knew that even if she lived to be a hundred, she would never have another mission this deeply personal to her.

Eventually, Detective Miller's squad car pulled into the parking lot. The two of them got out and headed inside to the main office to talk to Principal Philip Baines. Mr. Baines quickly recognized Kim—she was a former student, after all—but was quite surprised to see her show up in his office with a police officer at her side. Moreover, the normally kind and friendly girl looked like a volcano about to explode, and the policeman with her also had a very serious expression. It was clear that she wasn't here for a friendly visit.

"Hello, Kimberly. It's certainly been a long time." Mr. Baines smiled warmly at his former student, who did not change her angry expression one iota. "Is this about your brothers? They have been quite the troublemakers lately—"

"It's about Jim and Tim, all right," Kim snapped. "And right now I don't give a damn about what they've done to get in trouble. Yes, they can be wild. I should know, since I live with them. But they have a right to be safe at school!"

Detective Miller pulled out his search warrant. "Mr. Baines, Jim and Tim have made some extremely serious allegations against one of the teachers here, Hunter Gray. They told us that he molested and raped them during their detention yesterday."

Mr. Baines's jaw dropped. "I—what?"

"That's not all. The boys also claimed that he recorded what happened on his cell phone, and we have a warrant to search that phone. If what Jim and Tim said is true, then it's important evidence for our investigation, and we'll need to file additional charges for production of child pornography."

"Certainly. Head right on over to the gym and do whatever you have to do." Mr. Baines glanced at the clock. "As a matter of fact, you came at a good time. This is his planning period, so there won't be any students there."

"Perfect." Kim took off for the gym, moving so fast that Detective Miller had to scramble to keep up with her. With Kim in the lead, the two of them entered the middle school gym, then headed into a small office on the side. Sitting at a desk there, engrossed in some paperwork, was Mr. Gray.

Mr. Gray had only been with the middle school for a couple of years, so Kim had never met him before. Looking at him now, he certainly didn't come across like the monster that he was. He was wearing a Middleton Mad Dogs shirt, and had quite an athletic build. He appeared to be in his late twenties, with dark brown hair and a well-maintained suntan that was quite attractive. In fact, if Kim hadn't already loathed him with every fiber of her being, she would have thought he was hot—a fact that profoundly unsettled her. There was clearly no way to identify predators like Mr. Gray from appearance, because they looked just like everyone else.

Hearing someone enter his office, Mr. Gray looked up from his work. As he saw Kim and Detective Miller, his expression changed ever so briefly to one of terror. He knew—and Kim knew that he knew—EXACTLY why they were here. But he quickly hid his real feelings behind a mask of friendliness.

"Why, hello! What a nice surprise. An honor to meet the world-famous Kim—"

Kim's death glare made him stop mid-sentence. "Don't even TRY to flatter me," she hissed at him with pure hatred. "Where's your phone?"

"My—my phone?"

"Yes, your phone," Detective Miller told him gruffly. "We have a warrant to look at it. Jim and Tim told us that you recorded them on it."

"Now, look. Jim and Tim are quite the little rascals and it wouldn't surprise me if they made up some wild story. But I can assure you—"

As it happened, Kim spotted his phone on a table behind him at that moment. Before Mr Gray could stop her, she leaped over him and picked it up. And before he or Detective Miller could stop her, she accessed the phone's video archive and played the most recent one.

That video was less than a minute long, but it would haunt Kim for the rest of her life. Sure enough, Jim and Tim were facing a classroom wall, naked as the day they were born. To Kim's horror, it looked like both of them were bleeding from their rear ends. And they were in utter hysterics. "P-p-please, Mr. Gray," Jim sobbed. "We're s-s-sorry. D-don't hurt us anym-more."

"Shut up, you little bitch," an angry voice that clearly belonged to Mr Gray shot back. "You've been very naughty boys, and naughty boys need to be taught a lesson. And just for mouthing off, I'll do your brother next." The camera got closer to the twins, and suddenly Tim screamed in pain. The reason why was thankfully off-camera, but it didn't take a genius to figure out what was happening.

End of video. The screen went black, and Kim was so angry and so heartbroken that she was physically shaking. How dare he? How dare anyone? What kind of sick mind would do this to children—HER LITTLE BROTHERS—and enjoy it? But as awful as the video was, it was good in one important way: Jim and Tim's story had been conclusively proven true. There was now no way Mr. Gray could claim in court that he was innocent. Mr. Gray knew that as well—and, realizing the game was up, tried to make a run for it.

"Hey! Stop! Get back here!" Detective Miller yelled at the fleeing suspect. He began to give chase, but Kim was already well ahead of him. With a burst of speed that astonished even her, she charged Mr. Gray and quickly caught up to him. Growing frantic, Mr. Gray pulled what look like a knife out of his jeans, hoping to intimidate Kim. It actually had the opposite effect, though. That was resisting arrest with a deadly weapon, so Kim now had legal cover to use aggressive force. And she very much wanted to use aggressive force.

Running towards Mr. Gray, she grabbed his right arm with her left so he couldn't use his knife, then punched him in the nose so hard she hurt her hand. Mr. Gray screamed in pain as blood began to spurt out of his nostrils, and there was a distinct crack as his nose bone shattered. The attack left him disoriented, but he still had the knife and remained a threat. Before her opponent could recover, Kim flipped him over her head and violently slammed him to the ground.

"YOU FUCKER!" she screamed at him as Detective Miller came running up to the scene. The detective, observing that Kim had already subdued their suspect, began administering first aid and advised Mr. Gray of his constitutional rights. Through it all, Kim watched Mr. Gray like a hawk, practically daring him to try and escape again so she could inflict more pain on him. It did not go unnoticed by Detective Miller. "You know, you're really something," he told Mr. Gray at one point, with a mixture of bemusement and contempt. "Of all the kids in Middleton, you picked Kim Possible's little brothers. Do you have a death wish, or are you just stupid?"
