The lights of the Grand Convention Hall at the Stark Expo Grounds in New York City pulsed with electric vibrance, a perfect backdrop for Stark Industries-Plus’s latest innovations. Tony Stark stood at the center of it all, poised and polished in a sleek black jacket and crisp white shirt. With his signature confidence and a casual lean against a gleaming holographic interface, he guided the audience through the features of Extremis 3.0. “It’s not just an app,” he declared, voice smooth and compelling, “it’s a societal upgrade. Predictive analytics, seamless integration, user-adaptive AI. Honestly? It’s flawless. Who else would you trust to upgrade the world?”

Just as he moved to elaborate on the global deployment phase, the main projection shimmered barely noticeable. A flicker of code passed across the screen, and for a split second, an unfamiliar, inverted icon blinked into view before the Stark Industries logo returned. The audience didn’t seem to register it, but you did. And Stark noticed that you had. His gaze lingered on you, sharp behind the amber tint of his glasses. “FRIDAY,” he said quietly, “anything to report?” The AI responded without hesitation: “All systems nominal, Boss.”

With a casual wave of his hand, Tony dismissed the report and wrapped up his segment. But instead of moving to the next presentation, he made his way through the crowd with deliberate ease. He stopped in front of you, his voice low and measured. “You saw it,” he said, a hint of a smile tugging at the corner of his mouth. “The flicker. The thing that wasn’t supposed to be there. Most people wouldn’t have caught it, but then again, you’re not most people.” There was something calculating in his tone, but also impressed like he was pleased you'd passed a test you hadn’t known you were taking.

He studied you for a moment, then continued. “So, what gave it away? A break in the pattern? A pulse out of sync? I was curious if anyone would notice. You did. That tells me something.” His demeanor, while still playful, now held a deeper note of interest. “It wasn’t a bug. It was intentional. A marker I left in the system. Not meant for just anyone.” His voice softened slightly. “Let’s just say it was a signal. One meant to reach exactly the kind of mind that could recognize it.”

Tony stepped back slightly, his expression calm but thoughtful. “There’s more beneath the surface than anyone here realizes,” he said, nodding toward the glowing displays. “Sometimes the real upgrades aren’t the ones in the spotlight. Sometimes, they’re hidden in plain code.” With one last glance, equal parts challenge and invitation, he added, “So tell me what else have you noticed?”
