Defective: A Past Unfolds

It's not until morning when Itachi realizes what he's done. Izumi's body from the previous night lays bloodied, scarred, and just as lifeless on the floor. And when Itachi sees it after his slumber, he breaks.

He falls to his knees, taking Izumi's colorless hand. His own hands shake and tremble as tears cascade down his face.

"I...Izumi?" Itachi cries. There's obviously no response. All that's left is a cold, dark-eyed stare back at him. "Oh, God... Oh, god, what have I done."

He shakes his head, not believing what he's seeing. And although he's in blood-soaked clothes, he still doesn't comprehend the weight of this situation.

"No," Itachi whispers, pressing his head to Izumi's patchy hair. "No. No. No! No, no!!"

He cries in anguish, for he really loved her. The anger that possessed him last night was not him. It wasn't who Itachi was.

"Please come back to me!" Itachi whimpers, pulling the body close to him, and yet, it hangs limp. Face deformed; skin flayed. It was hardly a body at all.

He remembers the last words she spoke to him and spoke them himself. He apologized as if that's the way to bring her back.

Before the grief fully sets in, rationale takes hold. Rationale tells him to stand up, tells him to call his parents, and tell them about the situation.

And he does that. In the haze of an erratic display of emotions, Itachi finds his phone and calls his father.

It answers within two rings.

"What is it, Itachi?" Fugaku asks in a bored tone.

"Dad," he doesn't hide the panic in his voice. "Dad, something bad happened. Izumi, she's... Dad, please, you have to help me. Izumi is hurt and..."

He doesn't finish his sentence, but already Fugaku is completely alarmed. "Son. Don't worry, I'll call the police, and they'll be over---"

"No!" Itachi shouts. His body shakes. "You have to do this yourself. I can't trust anyone but you and mom and Sasuke."

"Son," Fugaku speaks softly as if it were really his son in the other line. "You have to tell me what happened when I get there. Promise me."

"I'll tell you nothing but the truth."

...

When Fugaku arrives, Itachi is still in place, holding onto Izumi's limp hand. Fugaku covers his mouth, horrified at the sight before him. Bile creeps up his throat, but he swallows it down.

"Itachi," he speaks softly, keeping the fear and the need to tell suppressed. "What did you do?"

Itachi looks up from his spot on the floor, his body shaking as he tries to recall what happened. He drops Izumi's hand and stands. "Dad, I-I."

He never finishes cause he starts twitching. His words jumble and he smacks his head to restart his thinking.

Fugaku walks with caution, closer to the dead body and closer to the manic robot. "Itachi, you promised to tell me everything. What happened to Izumi? What did you do?!"

Itachi shakes. He grips his father's shirt, tears flowing down his face. "She's dead. I killed her! She's dead, and I killed her. I killed her because she was with Shisui. She was cheating on me for months. She said it herself! And I couldn't help myself. I was so angry. She called me fake. I wasn't enough for her, father. I was never enough for anyone."
