Wooyoung woke up suddenly and sat up. He felt oddly refreshed but confused as he looked around.

He was back in his jail cell, on his bed, and away from San.

Hongjoong must have used the sleeping serum on him as he was running for San... Wooyoung knew he shouldn't have done that, but part of him couldn't help it. Those words...

Whore.

Whore.

"No! I'm not!" Wooyoung shouted, punching his pillow as hard as he could. A few tears rolled down his cheek as he tried to get the thought out of his head. "I-I'm n-n-not..."

The door to his cell opened and Wooyoung turned to see both Yunho and Hongjoong walked in. They didn't look happy.

Hongjoong slammed the door behind him and glared down at Wooyoung. "What happened in there?"

Wooyoung found himself shrinking back under his harsh gaze and looked down at the floor. He hated that it was an instinct to look down whenever he felt intimidated.

"We are going to ask you one more time. I know we are all learning to work together, but I wasn't expecting an incident on the first day."

"Just tell us what happened so we can prevent it from happening again." Yunho said, coming to sit next to the younger on the bed.

Wooyoung brought his knees to his chest and stared at them. "It's like he was two different people. I... I don't know how to explain it. But he started..." Wooyoung swallowed the lump in his throat. "I don't think he's stable enough to have on the team. It sounded like he was looking for... For my weakness."

He saw the two cops exchange a glance out of the corner of his eye, but ignored it. Instead he focused on trying to stay out of the dark place he went to.

Whore.

He shook his head. No, he wasn't one... He wasn't...

"Wooyoung?" Yunho said softly. He reached out and placed a hand on Wooyoung's knee.

The younger would have flinched away if he wasn't already pressed against the wall. But at the same time... It felt nice. He could feel the concern radiating off Yunho.

"He called me a whore."

"You said it was like he was a different person?" Yunho asked, squeezing Wooyoung's knee gently.

"Yes. He seemed to be there, and then it was like he was someone different. And he kept saying 'we'. I'm sorry that I snapped. I promise I didn't mean to." Wooyoung finally forced himself to glance up and look at Hongjoong. He could hear his voice shaking. "Please don't leave me behind..." He whispered, bowing his head again.

"Wooyoung, we never said anything about leaving you behind. We just wanted to see what happened so we can get things straightened out." Hongjoong said, his voice softening along with his gaze as he crouched in front of Wooyoung.

Yunho moved a little closer. "We didn't expect things to go perfectly right of the bat. That would be ridiculous. Are you ok?"

Wooyoung snorted and looked down at the ground again. He was never going to be ok... Never...

"Yeah, I'm fine." He glanced up at the two in front of him.

"Ok. Get some rest, we will try another round of training tomorrow." Hongjoong said as both he and Yunho stood to leave.

Wooyoung nodded and closed his eyes as Yunho's hand left his knee and he suddenly felt better, yet so empty at the same time.

The tears came as soon as the lock clicked.

Yunho picked at his lip as he walked down the hall next to Hongjoong.

"So what do you think?" The older asked, glancing up at Yunho.

"I think I know what he's talking about. I went over the footage from the room and... I think I saw that change Wooyoung was talking about."

Hongjoong sighed. "So what should we do?"

Yunho glanced down and saw Hongjoong rubbing his eyebrow as they walked. He placed a comforting had on the older's shoulder. "I'll handle it."

"What?" Hongjoong glanced up at him. "No, I can't ask you do that."

"I want to." Yunho said, glancing at the ground. "You know I can kind of sympathize with him."

Great... That was the worst thing he could have said and he knew he was about to get a pep talk from his friend now. But he couldn't help it. It was true though.

And just as he predicted, Hongjoong pulled Yunho into his office and locked the door behind them. "You did not just say that."

Yunho took a deep and looked down at his shaking hands. "I did. And I meant it. He has the same look in her eyes that Yuri did." As he said this, he placed his fingers against his lips then reached out in front of him and grabbed at the air.

Hongjoong repeated the same action, which Yunho appreciated, then hopped up to sit on his desk. "And that's the reason why this makes me uncomfortable. You can't let your emotions take over just because you want to try and help him."

"But what if I'm the only one who can? I don't think he registers what happens half the time."

"Which I think makes his... Condition worse that Yuri's. I know she was diagnosed with severe bipolar disease, and the doctors were looking into the multiple personalities before she died... But there was never any conclusive evidence." Hongjoong said softly.

Yunho's vision started to blur as he sat down in the chair in front of Hongjoong.

"I'm surprised you even want to help him in the first place, if I'm being honest. I know how you feel about..."

"But if he's really sick like this, then the real San might not have known what he was doing."

"Yun..." Hongjoong sighed. "You're treading a really thin line."

He knew he was. There were so few documented and studied cases of multiple personality disorder that there was no way to tell if it was really what San had. It could be schizophrenia too. But Wooyoung said he spoke saying 'we' a lot. And they had all seen San talking to himself.

Whatever it was, Yunho found himself wanting to at least try.

The pair sat in silence for a long time. This was just making their mission a bit more complicated. But... Even if San couldn't be a part of the team, he deserved a chance to be happy. Right? But if he really was the one to kill all those people...

It was all so confusing, and it hurt.

Yunho stood up and walked out of the office, knowing that Hongjoong wouldn't try to stop him. Not right now.

He walked to the break room and put on a fresh pot of coffee, waiting anxiously for it to brew as he clenched his hands.

This was crazy. Did he really think he could help a mass murderer? Someone who could be worse than Yuri?

Her bright smile flashed across his vision. Everyone had always said they could be twins even though she had been five years older than him. Yuri had always been such a bright, positive person. She loved to sing and dance, something the two of them used to do together often. And her laugh could light up a room.

Until 'the flip' happened, as Yunho called it.

Yuri would suddenly turn violent, often times throwing plates or other dishes at him before resorting to hitting him whenever he tried to restrain her. She would scream and scream until her voice cracked, then scream some more. And most of the time she would yell things like how much she hated him and wanted him to die.

Her episodes were never the same length either.

Hongjoong had witnessed a couple of them when Yunho first joined the force. They had been out on patrol together when Yunho got a call that officers were needed at his house.

He had always beat the ambulance there was able to restrain his sister. But it wasn't easy.

Things had been so unpredictable too, so they had had a long conversation one day while she was Yuri and she begged him to get a job and live his life.

She was taking medication to try and balance out her emotions and brain chemistry, and it worked most of the time. But if she wasn't on time when taking her pills every day, that's when she was more likely to have an episode.

Once again, Yunho placed his fingers against his lips and grabbed at the air. "I miss you Big Sis..." He whispered before pouring a cup of coffee.

He drank one while standing in front of the pot, letting its warmth seep into him.

He drank a second one while searching through his phone for a contact. After pressing dial, he waited with baited breath as it rang.

"Hello?" The deep male voice he knew so well said on the other side.

"Hey Doc, it's Yunho."

"Yunho? God, how long has it been?" The man said, exhaling sharply.

"Three years. I... I have a favor to ask. Can you come by the precinct? And... Bring your files."

"What's going on?"

"I need you to do an evaluation for me on one of the inmates. Please?" Yunho asked, his voice getting soft.

He heard the doctor sigh. "Yeah. I can be over in just a bit."

"Thank you." Yunho hung up the line and went to tell the front desk to expect a Dr. Kim Namjoon before he returned to the break room to pour cup number three.

Slowly but surely, he felt his nerves calming as he sipped on this cup. Soon he was calm enough that he asked for San to be brought to one of the interrogation rooms.

Hongjoong and Yunho greeted Dr. Kim as soon as he was checking in and filled him in on what's going on. His eyes widened in surprise when he was told about their plan with the team, but then his forehead creased with concern when they told him about San.

"Ok, I'll take a look." He said, following Hongjoong into the room on the other side of the one way mirror joined with the room San was in.

Yunho topped off his coffee before stepping inside.

His heart broke a little when he saw the concerned look on San's face. "Am I in trouble? I did something to Wooyoung, didn't I?"

"You don't remember?" Yunho asked, keeping his voice calm and gentle as he sat across the table from San.

He was free of chains since he had his bracelet now, so Yunho was still able to relax knowing Hongjoong was watching everything and was ready to inject San if needed.

"No... Well. I remember going into the room and watching him throw knives. Then..."

"Nothing? You don't remember calling him a whore?"

A frightened look crossed his face and he covered his mouth.

"I'll take that as a no." Yunho said softly. "It's ok San. I want to try and help you."

The younger looked down at the table and whimpered, then turned his head to the side. "They are supposed to be my team. I can't hurt my team."

Yunho sat back and watched as a pained looked crossed the other's face.

"I know. I know... But..."

Then his head twitched and he rolled his shoulders. He lifted his head up and locked eyes with Yunho. His eyes were cold and black now as they narrowed. "We didn't mean to offend. Please let us apologize to the boy."

"We?" Yunho asked, sitting up a little straighter.

"I-I. I didn't mean to offend." The younger corrected. A small sneer crossing his face.

"San, are you ok?"

"San is... I am fine. Just tired from training. May I go rest now please?" His voice seemed forced and his head kept twitching.

Yunho clenched his jaw. "Whoever you are controlling San, I want you to leave him alone. You can't win this."

The younger started laughing and his head fell back.

Yunho jumped out of the chair and ran to him. He placed his large hands on either side of San's face. "San. San listen to my voice. Come back San."

San twitched in his hands and his eyes closed for a long moment before they opened up to reveal pale blue eyes. "Y-Yunho? What happened? What did I do?" He whimpered before clinging to Yunho by wrapping his arms around him.

Yunho held him close and gently stroked the back of his head. "Shhh, it's ok." He glanced over his shoulder at the mirror, knowing that Dr. Kim and Hongjoong were standing on the other side watching this.

He took San back to his cell and got him tucked into bed before walking back to Hongjoong office.

Dr. Kim was pacing back and forth slowly while muttering to himself.

"Well?" Yunho asked after closing the door.

"You were right to call me. I think we've definitely got a severe case on our hands. And this isn't the first time you've witnessed this? What is he in here for?"

"Murder." Hongjoong said, crossing his arms. "But he doesn't seem to remember them."

The doctor nodded. "Yes. And I'm guess you want to treat him?" He asked, raising an eyebrow as he looked and Yunho.

"Please. He deserves a chance."

Dr. Kim sighed and pulled out his phone. He called the local pharmacy and ordered a few different prescriptions and asked that they be delivered to the precinct. "I'll want to examine him as often as you'll let me." He said, turning to Hongjoong.

He nodded and glanced at Yunho. "Do you really think it's worth it?"

"You're the one who saw something in him and wanted to interview him for the team." Yunho shot back, not wanting Hongjoong to question his decision to help.

"I know. But I didn't think it would be this bad." Hongjoong mumbled while rubbing his eyebrow.

"Well until we know if the medication will help, I'd advice keeping him away from any action and keeping a watchful eye on him." Dr. Kim said, glancing at both of them. "I'll be in contact to set up a schedule with you." He shook their hands then left.

The pair let out a collective sigh.

"Thank you." Yunho said quietly.

"You know I will always support you." Hongjoong walked over and took his hand. "But if he becomes a danger to any of us, especially you, I won't hesitate to take action."
