**Chapter 6: Shadows of the Past**

The days turned into weeks as Harry and Draco continued their training with the Avengers. They were making progress, but the tension between them was still palpable. Old rivalries and wounds resurfaced as they worked together, their opposing magical backgrounds and personalities causing friction. During a training session, Harry and Draco were paired together to take down a group of simulated enemies. They worked in tandem, their movements fluid and synchronized, but their banter was laced with tension. "You're not exactly the most skilled wizard, are you?" Draco sneered, his eyes glinting with challenge. Harry smiled wryly. "I think I can hold my own, Malfoy." Their instructor, Captain America, intervened, his voice calm and authoritative. "Let's focus on teamwork, guys. We need to work together to take down Thanos." As they continued their training, Harry couldn't help but notice the way Draco's eyes seemed to flash with anger when he was challenged. It was a glimpse of the old Draco, the one who had been his rival at Hogwarts. But there was something else there, too, something that made Harry's heart skip a beat. One evening, as they were walking back to their quarters, Draco fell into step beside him. "Potter," he said, his voice low and smooth. "Malfoy," Harry replied, his eyes fixed on the floor. They walked in silence for a moment, the only sound the soft hum of the Avengers Compound's machinery. "You know, I never thought I'd be working with you again," Draco said, his voice tinged with a hint of irony. Harry raised an eyebrow. "I could say the same about you." Draco chuckled, a low, husky sound that sent a shiver down Harry's spine. "I suppose we make an unlikely team, don't we?" Harry glanced at him, their eyes meeting for a brief moment. He felt a spark of attraction, but quickly looked away, his heart racing. As they approached their quarters, Harry realized that he was starting to see Draco in a different light. The Slytherin's arrogance and condescension were still there, but there was something else beneath the surface, something that made Harry curious. That night, as he lay in bed, Harry couldn't shake the feeling that he was getting to know Draco, really know him, for the first time. And he wasn't sure if he liked what he saw. The next morning, as they gathered for breakfast, Harry caught Draco's eye across the room. For a moment, they just looked at each other, the tension between them palpable. Then, without a word, Draco turned away, leaving Harry to wonder if he had imagined the whole thing. But as they sat down to eat, Harry couldn't help but feel that something had shifted between them, something that would change the dynamics of their relationship forever. As they ate, Black Widow approached them, her expression serious. "Guys, we need to talk about the mission ahead. We have reason to believe that Thanos is planning to attack a major city." Harry's eyes narrowed, his mind racing with possibilities. He and Draco exchanged a glance, and for a moment, they just looked at each other. Then, without a word, they nodded, their faces set with determination. They were ready to face whatever challenges lay ahead, together. The city lights twinkled in the distance as they walked toward the briefing room, the tension between them a reminder that their alliance was still fragile, but their determination to succeed was unshakeable.
