Dr. K peeked through the small window to see who they were. She could easily make out Patient 7, and 8 since she'd worked with them before, but she couldn't recognize the third female patient. Patient 7 was carrying a broom handle, and Patient 8 a (medicine) needle with a strange green liquid inside it.

"They must have ran in here." said Patient 7 as he looked around.

"What makes you so sure?" asked Patient 8.

"Shut up and look." he ordered. As they looked around, Dr. K looked over to Dr. S who was standing next to Patient 13. Patient 13 was still rocking back and forth, hugging Tet as tight as he could.

Suddenly, they heard one of them starting to open the door next to Dr. K. Dr. S quickly ran behind the door as it opened. Patient 8 peered through the door. When he saw Patient 13 sitting in the center of the room, he stepped in.

"Hey, who are you?" he asked as he cautiously stepped closer to Patient 13. He didn't seem to notice him. When he looked around, he couldn't see anyone else. Patient 8 started toward the office. Just as he stepped through the door, he tripped and grabbed the nearest thing he could, which (unfortunately) was Dr. K's long hair. She let out a yelp of pain as he dragged her down.

Dr. S quickly ran into the office where Patient 8 had already recovered and held Dr. K by her hair. As he stood, he pulled Dr. K up and held the needle towards her neck.

"Leave her alone!" demanded Dr. S.

"Why? You put us through this everyday." said Patient 8 savagely. Then Dr. S felt something hit him hard in the head, knocking him out. Patient 7 and the woman stepped in.

"Good Nobunaga, ya' got 'er." stated Kouga evilly.

"Hey, I know her, she's Inuyasha's doctor." said the woman. Kouga turned and looked at the patient still sitting in the cooking area.

"Hey Inu, you want the pleasure?" he asked bluntly. Patient 13 twitched as he slowly stood. He turned and placed Tet in his waist band as he walked in.

"So I can finally hurt someone and not get in trouble?" asked Patient 13 looking at them all. Dr. K couldn't believe it.

"Sure go ahead." said Kouga.

"Put that needle down first, we don't want to hurt one of our own." said the woman. Nobunaga (stupidly) set the needle down and held Dr. K so she couldn't move away.

Then Patient 13 quickly grabbed Patient 7 and the woman by the throat and lifted them into the air.

"What are you doing!" demanded Kouga trying to break his grip.

"You said I wouldn't get in trouble." answered Patient 13. He twisted his wrists, and two loud pops sounded from them as their bodies fell limp.

"Traitor!" yelled Nobunaga, but before he could reach for his needle, Patient 13 grabbed him by the hair and jerked him away from Dr. K and put him in a head lock. "Let go!" he struggled to speak through Inuyasha's grip.

"Not if you tell on me." said the psycho. Dr. K screamed in horror as Patient 13 held him in one arm and ripped his head off with his free hand.

As blood gushed from the headless corpse, splattering all over Patient 13, he slowly stepped closer to Dr. K, still holding Patient 8's head.

"In-Inuyasha?" Dr. K stuttered in fear. He twitched again, dropped the head, and grabbed her by the shoulders.

"Are you okay?" asked Inuyasha calmly. Dr. K was too shocked to answer at first. "Dr. K, are you hurt?" he asked again with concern in his eyes.

"No." she finally managed to say.

"Good, can we leave now?" he asked releasing her and leaving two bloody palm-prints on her sleeves. Dr. K looked into his eyes, and could tell that he was his normal (good) self again, and sighed.

"Yeah, let's go." she said trying to calm herself despite the three corpses around her. Patient 13 waited for her to leave first; as he walked, he picked up the broom handle from Kouga's corpse and lifted Dr. S over his shoulder.

When they walked out of the cafeteria, Patient 13 handed Dr. K the broom handle.

"Just in case I get hurt." he told her. She scanned him for a moment. He seem to be void of the fact that he had just killed three people, and was now covered in blood. "Where do we go now?" asked trying to get her attention. Dr. K then realized that he had a point. Where could they go?

"We need to get out of the building. So I think we need to find the stairs." she told him.
