A/N: Hey, sorry it's late, I got busy! But it's here, never fear!
The headcannon behind this was that Marinette is a really big fan of Batman and superheroes in general (hehe, she has her dream job) and Adrien has never seen any superhero movies because his dad deemed them "too childish and violent".
Prompt: "Adrien walks up to Marinette and whispers "I'm Batman" or something…" -My sister who only knows the names because I told her.
~Enjoy!
"The new Batman movie comes out tonight! I'm so ready for this!" Alya pumped her fist in the air, with classes finally being over for the day, she could be as loud as she wanted without getting in trouble.
Marinette nodded, her own eagerness showing through as she bounced in place, waiting for Alya to finish up at her locker so they could head over to the dark haired girl's house to wait for the movie.
"And the best part is that it's the weekend, so we can actually see the midnight premiere!" Marinette gushed, unaware of the blond model walking up behind her.
"Midnight premiere?" Adrien asked, he and Nino walking into the conversation after hearing about a trip to the movies.
Alya turned and smiled at the two boys as she answered, "oh, Marinette and I are going to see the new Batman movie, you wanna come with?" She smiled at the boys while her best friend just stood there smiling like an idiot, she was adorable yet starstruck.
"Dude, yes! I love Batman, I've been looking for someone to go with, Adrien here doesn't know anything about anything!" Nino laughed, slinging his arm around Ardien who blushed sheepishly, shrugging at his lack of Batman knowledge.
Marinette glanced at Adrien, silently asking if he actually knew anything about Batman. but getting no further with conversation.
"Yeah, you can come, I'll text you the details," Alya smiled, slinging her bag over her shoulder and getting ready to go.
Alya stole a glance at her friend and her crush, noticing Marinette wishing to ask the boy something, but being unable to ask because Adrien made her shy.
Alya laughed and rolled her eyes, turning her attention to the blond before speaking, "hey, do you wanna come too? I know you don't know about Batman, but you can still hang out at the movies with us."
"Yeah, it'll be fun! I was gonna drag you anyway, man!" Nino added, turning his attention to his best friend, who seemed to light up at being invited along.
"Really? You wouldn't mind? I'd love to tag along!"
"Great! Text you the details in a bit then!" Alya waved, dragging Marinette along as they walked to the bakery.
"Alya, I owe you so much!" Marinette gushed, hugging the girl's arm and smiling at her, still over the moon about the upcoming outing with her crush to her favorite series ever.
"I know!" Alya laughed, the two girls laughing and talking all the way to the bakery.
Adrien was in the bathroom at Nino's house, the only place he could talk to Plagg without being caught.
"Plagg, I know that Marinette is Ladybug, but how do I tell her I'm Chat Noir?" Adrien asked, perching on the edge of the tub, sighing as he tried to puzzle this out.
He had accidentally discovered Ladybug's secret identity when she her transformation ran out right after a fight. Ladybug, Marinette at the time, was terrified Chat wouldn't like her knowing who she was, but Chat made sure that Marinette never thought she was less around him again.
But now came the question of how to reveal himself. He loved seeing Marinette acting like herself around Chat Noir and when she was Ladybug, but the poor girl seemed to clam up whenever his alter ego appeared, so if he could make her feel like she already knew him, then maybe they could become friends. The only problem was finding a creative way to tell her who he was.
"How about you tell her you're Cat-man? Like, like Batman, but a cat!" Plagg laughed, shoving cheese into his mouth and flying back into Adrien's jacket, signalling that the conversation was over, because they were still in Nino's bathroom.
"Well, Cat-man it is, I suppose," Adrien shrugged, the idea already forming in his mind.
Marinette and Alya saw the two boys waving them up to the front of the line.
"Hey guys! We were out eating and then you texted so we just decided to save our spots in line, hope that's okay," Adrien winked, lifting the rope that kept the line close to the theater to allow the girls to hop in line with them.
"Yeah, sorry we're a little late, we went to the new Chinese restaurant but it was packed! But look, I got us fortune cookies!" Alya handed out the cookies to the rest of the teens and opened her own, laughing at the fortune.
It was an unspoken rule between the four teens not to share the fortunes until an hour has passed, a tradition they started when they first began hanging out and it just stuck with them.
Alya turned to Nino, starting a conversation with the boy, forcing Marinette to either talk with Adrien or stand around awkwardly.
"Hey, Marinette, can I tell you a secret?" Adrien asked in a hushed voice, pulling the girl a few steps closer to the rope and away from their friends.
"I-I, uh, sure!" She tried to say calmly, unable to keep it cool.
Adrien smiled and leaned down a bit to be closer to her height.
In the worst Batman impression anyone has ever heard, Adrien whispered, "I'm Chat Noir," and opened his coat a bit, allowing Plagg to peak out and give a wave.
Marinette would've screamed if she could, but all she could do was stare at the boy, his terrible Batman impression taking away most of the shock.
"You make the worst Batman, you silly kitty."
