The video began with footage of the crime scene, the General's daughter lying dead, Y/n standing nearby with bloodied hands. The image then shifted to the courtroom, where Natasha took the stand, her testimony damning Y/n. Each scene was carefully edited to paint Natasha as the betrayer, the one who had condemned Y/n to a life of suffering.

"Natasha betrayed you," the voiceover intoned. "She put you through hell."

Y/n's eyes glazed over as she watched the video, the words and images seeping into her mind like poison. The torture had been relentless, breaking her body and spirit, but the psychological warfare was the most devastating of all.

Valentina entered the cell, her presence a mix of menace and false comfort. She sat beside Y/n, her hand gently touching her shoulder.

"Darling," Valentina whispered, "you must understand that I'm not your enemy. Natasha is the one who betrayed you, not me. She's the reason you've suffered." This was the last thread and Valentina was pulling the it enjoyably.

Y/n's eyes were vacant, her spirit eroded by the constant barrage of lies. "Natasha betrayed me," she repeated, her voice hollow.

Valentina smiled, satisfied with the progress. "That's right, my dear. But you don't have to suffer anymore. I can help you. We can make them pay for what they've done to you."

Y/n's gaze slowly focused on Valentina, a spark of trust flickering in her eyes. The daily torture, both physical and psychological, had worn her down. Valentina's manipulative kindness seemed like a lifeline in her sea of despair.

Valentina's guards began to train Y/n, turning her into a weapon against the Avengers. She was subjected to rigorous physical training and combat simulations, her body pushed to its limits. Every time she hesitated, the video would play, reminding her of Natasha's betrayal and fueling her rage.

"Natasha betrayed you," the voiceover echoed in her mind, driving her forward.

One night, after a particularly brutal training session, Y/n lay on her cot, her body aching and her mind fractured. Valentina entered, bringing a tray of food and a soft blanket. She sat beside Y/n, her expression one of calculated concern.

"You're doing so well, Y/n," Valentina said softly. "Soon, you'll be strong enough to confront Natasha and the Avengers. They will pay for what they did to you."

Y/n looked at Valentina, her eyes filled with a mix of pain and newfound loyalty. "I don't know if I can do this."

Valentina gently cupped Y/n's face, forcing her to meet her gaze. "You can. And you will. Because they need to understand what they've done. They need to pay."

Y/n nodded slowly, the last remnants of her resistance crumbling. "They need to pay."

Days turned into weeks, and Y/n's transformation continued. The video played on a loop in her cell, reinforcing the narrative of betrayal. Valentina's manipulations grew more insidious, blending cruelty with moments of false kindness to keep Y/n off balance and dependent.

One evening, after a particularly intense training session, Y/n was summoned to Valentina's office. The room was lavishly decorated, a sharp contrast to the bleakness of the warehouse. Valentina sat behind a large desk, a folder in front of her.

"Y/n, it's time," Valentina announced, her voice firm. "You're ready for your first mission against the Avengers."

Y/n stood before her, a mixture of dread and determination in her eyes. "What do you want me to do?"

Valentina slid the folder across the desk. "Your mission is to infiltrate their compound and gather intel. We need to know their plans, their weaknesses. And most importantly, we need to find a way to bring Natasha to her knees."

Y/n took the folder, her hands trembling slightly. The path before her was dark, filled with vengeance and betrayal. Yet, she felt a grim sense of purpose. Valentina had twisted her mind, making her believe that this was the only way to reclaim her life.

"Understood," Y/n replied, her voice steady despite the turmoil within.

Valentina smiled, a predatory gleam in her eyes. "Good. Remember, Y/n, I'm the only one you can trust. We're in this together."

As Y/n left the office, her heart ached with the weight of her mission. The video's haunting words echoed in her mind. And now, she was ready to make her former friend pay for the years of torment and suffering.
