Backstage at San Diego Comic-Con was a controlled storm of excitement. The low hum of the crowd beyond the heavy curtains rumbled like a distant thunder, growing louder with each passing second. Lights pulsed and shifted, camera flashes already popping like distant fireworks from the packed auditorium.

You stood just behind the curtain, half-hidden in the shadows, your heart racing in your chest as you peeked out at the massive audience. It was surreal.

This was it.

Your official debut into the M@rv3l Cinematic Universe.

You’d been acting since your early twenties—indie dramas, network series, the occasional box office surprise—but nothing quite like this.m. You were now part of the biggest cinematic universe in the world, and the entire fandom was waiting to see who you were about to become.

But the moment didn’t feel quite so overwhelming… not with Sebastian Stan standing beside you.

He gave you a quiet glance, his energy calm and grounded even as the moment built around him. He’d been through this before. But this time was different for him too—he was finally getting the standalone movie Buck B deserved. And you were part of it.

The world didn’t know it yet, but you’d be playing Davina—a Hydr@-engineered super soldier like Bucky, someone who escaped the program before he did. In the upcoming film, the two of you would be reunited—fighting together, healing together, and, maybe… falling for each other.

The chemistry was already there.

Maybe it always had been.

You shifted your weight anxiously, smoothing your palms along the sides of your jacket, eyes flicking nervously to the monitor beside the curtain. The screen displayed clips from past moments, building the hype before the reveal. You could hear the crowd reacting in waves of excitement.

Sebastian’s gaze dropped to your hands. Without a word, he reached over and gently took one, his fingers lacing through yours with ease and familiarity. His touch was warm, steady.

“You’re gonna be fine,” he said softly, his voice a low hum beneath the noise.

You exhaled a shaky breath, but nodded. “Yeah… I know. I’m just—so excited. I mean, the fans are excited for the movie, I just hope they’re excited about who I’m playing.”

Sebastian turned to you, giving you a smile that was equal parts amused and sincere.

“Who wouldn’t be?” he said. “Everyone loves you, {{user}}.”

Your lips curled into a smile, the nerves still buzzing, but softer now.

“Well… people have been waiting for Buck to catch a break. Maybe Davina is that break.”

He looked at you like he wanted to say something more—something that sat just behind his smile, resting in the space between silence and courage.

But before he could speak, his name was called.

The announcer’s voice echoed from the stage: “Give it up for the man behind the Winter S0ldi3r himself—Sebastian Stan!”

Sebastian gave your hand one last squeeze before letting go, and without hesitation, leaned forward to press a soft kiss to your forehead.

“See you out there,” he said with a wink, and then he was gone—disappearing through the curtain into a blinding wall of lights and thunderous applause.

You were left alone in the wings for a moment, your heart still pounding, your name suddenly echoing in your ears as the host spoke again:

“But we’ve got a surprise for you all—someone we know you’re going to love. Joining the film and making her debut, please welcome the incredible {{user}} Parker!”

The curtain pulled back.

The lights hit your face.

And the crowd exploded.
