Work Text:
It was 2:00 AM. Spider-Man was quietly delivering a small, non-lethal energy scrambler he’d confiscated from a small-time crook to the back entrance of Avengers Tower. He had a designated drop point—a secure, unlabeled bin—for tech he deemed too dangerous for the NYPD but not serious enough for a direct Avenger hand-off.
As he was sliding the device in, a light flickered on in the service bay, revealing a figure hunched over a workbench. It was Bruce Banner, dressed in a rumpled lab coat and thick-rimmed glasses, completely engrossed in a holographic display showing complex molecular structures.
Bruce looked up, startled, then blinked at the figure in the red and blue suit.
“Oh. Hey, Spider-Man,” Bruce said, his voice quiet and slightly tired. He wasn't scared; he was just mildly annoyed at the interruption.
Peter froze. Unlike the others, Bruce didn't get immediately professional or protective. He was simply Banner, the mild-mannered genius.
“Dr. Banner! Sorry! I didn’t mean to interrupt,” Peter stammered.
“It’s fine. Just trying to figure out why the sub-atomic bonding sequence on Vision’s vibranium lattice is degrading,” Bruce mumbled, rubbing his temples. He walked over, picked up the scrambler Peter had just dropped, and examined it with immediate, intense curiosity.
“Huh. Where’d you get this?” Bruce asked, turning the device over in his hands. “The energy output signature is crude, but the core sequencing… there’s an efficiency here. Who built this?”
Peter felt a strange sense of familiarity. This was their rhythm—the quiet, mutual appreciation for engineering and problem-solving. It was a connection that transcended the memory of their friendship.
“Just a guy,” Peter answered vaguely. “He was trying to, uh, knock out traffic lights.”
Bruce looked at him keenly. “No, not the thief. The tech. The way the primary capacitor feeds the flux stabilizer. It’s elegant. It solves a specific energy redundancy problem I encountered two years ago in the Tower’s central grid. I had to solve it with three components; this guy did it with one.”
Bruce squinted at the device, then looked at Peter. “Did you modify this? You seem… very interested in how it works.”
Peter felt a deep warmth. Bruce was recognizing his mind, even if he didn't recognize his face.
“I… I tinkered with it a little to deactivate it,” Peter admitted. "The original design had a flaw in the feedback loop; it was going to blow up in the guy’s hand."
Bruce’s eyes widened slightly. He immediately went back to the workbench, pulling up a new holographic schematic.
“A flaw in the feedback loop… yes, of course! You’re right!” Bruce tapped the air, manipulating the schematic. “See? The induction coil placement causes a massive overload under sustained use. How did you know that, Spider-Man? That requires intimate knowledge of high-frequency power dynamics.”
Peter felt a pang of painful triumph. He couldn't say, Because you taught me the basics of the Stark power grid, Dr. Banner.
“I just… have a good eye for patterns, I guess. I see the math,” Peter said, keeping his voice carefully modulated.
Bruce stopped working. He turned completely around, taking off his glasses and looking at Peter with a heavy, serious gaze. He wasn’t looking at Spider-Man; he was looking at a puzzle.
“You know, I knew a kid once,” Bruce said softly. “He was just a kid, but he had that same kind of mind. He saw the world in equations and vectors. He was brilliant, maybe the smartest person Tony ever met.”
Peter froze, trying desperately not to move.
Bruce frowned, shaking his head. “I can’t place him. Tony lost... a lot of people over the years. But sometimes, when I work on something complicated, I get this feeling—like a memory I can’t access. A feeling that someone very specific should be here, helping me calculate the variables.”
He looked back at Peter, and a profound, gentle sadness crossed his face.
“You feel like that missing variable, Spider-Man,” Bruce murmured. “You feel like a piece of the equation that just vanished.”
He held up the scrambler. “Send me your contact info. I want to hire you as a consultant. Anonymous, contract basis. We need a mind that sees patterns like this.”
Peter's heart swelled. It wasn't the love of a friend, but it was the professional, intellectual respect he’d always craved from Bruce.
"I can't, Dr. Banner. I'm busy. Too much to do," Peter said, stepping back toward the service door. "But if I find any more interesting tech, I'll drop it off. You keep fixing the world, okay?"
Bruce nodded slowly, still holding the device, his eyes distant as he processed the phantom memory. “You too, Spider-Man. Take care of yourself.”
Peter swung away, the heavy silence of the night now replaced by the warm buzz of Bruce Banner's scientific appreciation. He was still invisible, but his brilliance, the very core of who Peter Parker was.
