Ed's heart began to race. "Kat!" he called hoping to get an answer, "Where could she be? It's not like she'd go wandering off by herself!" At this point Ed and Al had been searching for hours upon hours. "I know, Brother," Al replied, "We've got to keep looking though!" The brothers searched all day that day and into the night. They asked people around and searched practically every building in the area. "We're not getting anywhere!" Ed shouted as he hit a brick wall with his automail, "I swear I'll kill Roy if anything happens to her!" Al looked to the sky as it began to rain, "Don't worry Brother. Either we find her or she finds her own way back. She always does." Ed was confused for a moment then he knew exactly what Al meant, "Yeah..."
The next day wasn't any better. Ed and Al spent the whole night in the pouring rain looking they had gotten no sleep at all. "Brother...please. I'm tired and cold. Can we please-"
"No! Al! We're not stopping until we find her!" There was only one place in that area where they hadn't looked. An old warehouse on the far north of the city. "She's got to be in there." Ed burst through the closed doors into the dark. "Al, stay here." Al did as told and stayed put as his brother disappeared into the shadows.
Ed ran into another dark room that had a single light illuminating in the middle of it. He ran for the next flight of stairs but, as soon as reached the light, laughter reverberated off the walls. It was a familiar voice that Ed knew well. "Kat?" He said in a whisper. He turned to see her curled up in the corner. "Kat!" He exclaimed sprinting towards her. He stopped halfway and realized that her clothes were ripped and torn...and she was covered in blood. His eyes widened as he noticed the blood stained knife lying next to her. But, there was no news of any murders. Could she have been injuring herself? She picked up the knife and stood. Ed couldn't see her face but he could tell she was smiling. "Hello, stranger. Are you here to play?" The word pierced Ed's heart like a poison arrow.
"K-Kat I was looking for you..." She lifted her head and tilted her head to the right to reveal eyes that were now as red as the blood that covered her body. "Looking...for...me..?"
"Yes, You. You remember me don't you? I'm Ed.."
"Why the hell would I remember someone pathetic like you? I think I should kill you because you're ignorant and disgusting. A human you are!" Nothing she was saying made any sense. Ed was terrifired. She lunged at him only to be brought back by a chain around her neck. "Kat!" Ed yelled still worried about the girl that clearly was no longer his. She sat there and tilted her head to the left, "Why do you keep calling me that?" Then a voice from nowhere said, "Now, Now, my pet. Don't confuse him with your silly questions." A man in a military uniform stepped out from the shadows. "Hello, Edward. My pet and I have been waiting for you." Kat sat in the corner snickering and smiling madly. "What did you do to her?" The man didn't answer Ed's question. "Answer me, Dammit!" The man laughed loudly, "How long do you think you could've kept the fact that she was from another world from us, Edward?" Ed gasped softly, "No..."
"Yes Edward. We found out. And now...she's my little pet and she only knows one trick and that trick is to kill."
"How many?" Ed asked looking down.
"Pardon?"
"How many experiments did you do on her?"
"Enough to make all the trauma from her life to backtrack it's way to her head, thus, making her go completely mad" Ed's voice cracked with sadness. "Damn you...She didn't deserve this! Now, she's gone and it's all your fault!" Ed transmuted his automail and ran towards the man but, before Ed could get to him, he unlatched Kat's chains. "Kill him." She sprang up and transmuted the knife into a cutlass blocking Ed's automail. All the while, smiling and laughing. "Daddy told me to kill you, so I guess you gotta die stranger!" They fought and fought, then finally, Kat pinned Ed to a wall and got ready to stab him in the throat when she stopped in mid-swing. Al rushed in at that very moment. His eyes became wide and tears began to well in them. "Brother...What have you done...?" Ed had stabbed Kat strait through the heart. Blood flowed from her mouth and tears fell from her eyes. Ed cried silently as her body fell to the ground and he fell to his knees. He began to sob; he had just killed the only person he truly loved. The only person who truly understood him. Ed held her lifeless body close to him as military personnel flooded the room and arrested the man who had done this to Kat. Hawkeye stepped over to Ed. "Ed...are you Ok-" The she saw what he was holding. All other noise became silence as Ed put her body back down. He kissed her then whispered, "I...love you, Kat. So much. I'm sorry..." Then he stood, "I want this place burned to the ground! Now!" As the warehouse burned Ed felt the rain on his skin as he silently whispered, "Goodbye..."
