Chapter 1

William will never forgive he so much as glanced at a monster, all he saw was yellow. He wanted justice for his little brother. Justice for the other children they had killed in cold blood. William didn't care if it killed him. Or if it killed them. Just because they were looking for freedom does not justify the fact that they killed innocent children to get it. That was a fact he could not overlook.

One day, he had been walking to his house from the grocery store. William had heard the sound of crying in a nearby alley. There was a monster child, a rabbit, cowering in the corner of an alley as three human children loomed over her. The trio seemed to be taunting her, tugging at her ears and kicking dirt on her white leggings. William knew bullying when he saw it, and was tempted to scold the trio. But something deep inside him told him to ignore it. To keep walking. Before he could though, the rabbit girl noticed him. She looked at him, a flicker of hope in her eyes. But that hope disappeared when their eyes met, and she resigned to her fate. The look in Williams' eyes were cold with an underlying spark of rage. He turned, and casually walked away.

It was two weeks after that his anger got the better of him. A Froggit hadn't been watching where he was going, and bumped into William. Unfortunately, the human was not in a good mood, and proceeded to beat the Froggit so bad he had to be hospitalized. When law enforcement arrived at the scene, they were shocked at Williams' behavior. It was a small town, and everyone knew each other. The local police were familiar with William, as he had often brought baked goods to the station that he and his brother had made from scratch. Each time they complimented them on their hard work, but the brothers would just laugh and tell them that it was their form of appreciation for keeping their town safe. So it unnerved them that it took four of their strongest to hold him down. At that point, they had to taser him to prevent him from hurting himself or others. Though, they could sort of understand Williams' feelings. Everyone at the station agreed that if their sibling was murdered by monsters, they too, would hate them. Not that they were fond of them in the first place.

When William woke up, he found himself in a cell. He combed his fingers through his short raven hair, groaning as he sat up. The door slowly opened, revealing David, a rookie officer that had blonde hair and bright green eyes. He motioned for William to step out of the cell, holding a pair of handcuffs. They walked down the hallway leading to the courtroom, Davids' hand pressed against Williams' strong, upper back. When they arrived at dark oak doors, William felt himself tense. Not about the trial, but about the amount of people, the amount of monsters he would see. There was no doubt that the Froggits family was there, along with his monster attorney. And William knew that no one in a thirty mile radius would be willing to stand up for a monster. Especially not against William.

Sans had heard about the brutality this kid had dished out against Froggit. He had nearly forgone the trial, but realized that since everyone else was going, he might as well go too. Sans was expecting the kid to be a little older, but he appeared to be fifteen at most. He was short for his age, except that wasn't what Sans was focused on. Although he couldn't see his face very clearly, he caught a glimpse of yellow.

"A soul of justice?" Sans murmured into his hand to avoid attention.

The skeleton had nothing to worry about though, as Frisk and Papyrus were focused on the teen that had walked in. There was something off about him, something that unnerved every monster in the room. And it wasn't just his violent tendencies towards monsters.

William sat in his designated seat, cuffed hands laying on the table. He had a calm composure, and his posture was rigid. David stood to his right while his lawyer was on his left. The lawyer, Eric, wore a plain black suit with a red bow tie, which complimented his red rimmed glasses. His hair was gray and the scruff growing on his chin was snow white. Eric coughed into his hand, purple eyes peering up at the judge. The judge seemed to get the message, hitting his gavel on his desk to quiet the crowd.

"What do you plead, William Bailey?" The judge looked at the teen with a neutral expression.

"I plead, guilty," William answered with bitterness, "But before you sentence me, I need to say something. To everyone."

The judge looked apprehensive, but nodded anyways. He hoped William wouldn't say anything rash. With the judges approval, William lifted his head. Sans could clearly see his eyes now. He CHECKED him, proving his theory that William was a yellow soul. But it was darker than most other justice souls, dimmer. Like it was corrupted. Sans was inwardly panicking. What if he was like Chara? Before he would worry anymore, William began talking.

"What I did to that Froggit was…" William struggled with the next words, "Unjustified, I know that. But what I did to that monster will never amount to the pain their kind has caused to us. They think they were in the right, gaining their freedom, and that we're the bad guys for locking them away."

William clenched his fists, and the guards stepped closer to him, ready to subdue him. But William just continued, "But what they did is unforgivable. Killing children for their own gain is sickening. Our ancestors should have just slaughtered all of them."

The room was quiet. Some of the more rowdy humans stood from their seats and clapped, cheering William on despite the horrible things he had said. Even those who weren't cheering were smiling, almost maliciously, towards the monsters. But the one thing they had in common was the sheer hatred in their eyes. Meanwhile, the monsters were nearly cowering from the constant pressure, although those who were stronger just gaped. They couldn't believe what this kid had just said.

Undyne was furious, absolutely appalled by this punk's attitude. Sure, they had made some mistakes, but the humans were the ones who attacked first. They were the ones who started mercilessly murdering as soon as they knew that monsters could absorb human souls. She stood, teeth bared, and glared at William. The teen did not back off though. No, he glared right back, and for a second his eyes glowed a brilliant yellow. Undyne's eyes widened in surprise. A magic user? Undyne was under the impression that mages had died out. Apparently not though.

Asgore sat there, thinking of the body of the boy wielding Tough Gloves and wearing a Manly Bandanna. The orange soul had told him that he had a brother to get back to, and that he wasn't going to back down from him. Was William that boy's brother? That would certainly explain his hatred for monsters. Asgore couldn't help but feel guilt and pity towards William.

The judge was not as thrilled as his fellow humans. He couldn't help but feel disappointed in William. He had changed so much after his brother died. William became prone to violence and was colder. Especially around monsters. But, those close to him could see that he was still the William that everyone knew and loved. Sweet, compassionate William. The one that would spoil his brother rotten and stand up for others with an unwavering sense of justice. All of them hoped that they were right, and William only acted so crudely around monsters.

"William Bailey, I, Judge Green, sentence you to two weeks in juvenile detention," Judge Green slammed his gavel down, marking the end of the trial. Undyne was outraged, and Frisk saw the sentence as unfair. That poor Froggit wouldn't be able to walk for another month, and William was getting off with a two week sentence?

"Your honor, I-" Frisk began, but was cut off by the angry snarls they were getting from the crowd of humans. They looked almost betrayed, and whenever they looked Williams' way Frisk noticed a sense of protectiveness in their eyes. Instead of speaking more, they merely looked towards William, who was being escorted away by guards that were almost twice his size. The boy turned around, catching Frisk watching him. He growled, and turned back.

Once everyone had left the building, Sans walked towards Frisk, who was conversing with Papyrus. The tall skeleton looked almost nervous. He was fiddling with his scarf and his eye lights seemed to glance side to side, as if he were watching for someone. Sans thought, 'That's unlike him. What's wrong?'

Sans poked his brother's humerus. Papyrus flinched, startled. But when he saw Sans, he sighed in relief, "Yes, Sans?" His tone set off alarm bells in Sans's skull. He sounded worried, not afraid, just worried.

"Is everything alright, Papyrus?" Sans asked, concerned for his brother. Papyrus just nodded, "It's just, the human, William… I felt so much… hate," he frowned. It was just like Papyrus to be worrying about someone who didn't deserve his concern. Sans shook his head, but said nothing.
