Marinette was so excited she was shaking. She had just gotten word that she had been accepted into an exchange student program with Gotham Academy. Not only would she be able to get away from Lila and the drama with the class, but she may also be able to find Batman and get some help with tracking down Hawkmoth. Marinette would be hosted by the Wayne family, who was sponsoring this whole program. Marinette was impressed by Mr. Wayne’s generousity. It is really generous of Mr. Wayne to set up and fund this whole program. He must be a really nice man. Marinette wasn’t going waste this opportunity. She would enjoy her time in America, and she would definitely find Batman before the program was over!

Bruce really hoped this crazy plan worked. He had learned several weeks ago about a blog based out of Paris called the Ladyblog. It mainly posted a bunch of nonsense about a girl named Lila who was clearly a liar. But that wasn’t what caught his attention. What caught his attention was a few stories posted between the interviews with the liar. These posts were about something called ‘akuma attacks’ and a supervillain named Hawkmoth who had been terrorizing Paris for years now. At first, Bruce just thought it was more nonsense, like the posts about the liar. But to be safe, he looked into it more, and was astonished to find out it was the truth. He learned everything Hawkmoth had done, all the different akumas, and about the local heroes: Ladybug and Chat Noir.
——————-
He was shocked to see that the heroes defending Paris were just kids. And while they have done great on their own, Bruce could tell they haven’t had any kind of combat training. If they go up against an akuma with real training, they would be at a significant disadvantage. Plus, they would likely not have any good strategy to discover Hawkmoth’s identity. Even if they keep winning against the akumas, they have to find and beat Hawkmoth or this madness will never end. He resolved in that moment to find these kids and help them. He focused on Ladybug and started to figure out her civilian ID. It took a few weeks, but he eventually found out she was Marinette Dupain-Cheng. She always disappeared once Ladybug appeared, and there were a few times that a security camera would see her duck into an alley, and then a few moments later, Ladybug would emerge. Once he knew her identity, he began to plan.
———————-
He decided the easiest way to get her to Gotham would likely be something regarding school. At first he thought of a class trip for her whole class, but decided against it. That idea wouldn’t work with the rest of his plan. Instead, he set up a student exchange program with Gotham Academy. He would host the student that was selected at his manor for the duration of the program and fund the entire thing. The academy didn’t think anything of it, used to Mr. Wayne’s charitable acts for the school. His one condition was that he got to choose the student. The academy agreed, it only made sense since Mr. Wayne was funding the program and would host the student as well.
——————–
Mr. Wayne made sure that the news of the program made it to Paris and was heavily advertised. He even sent the information to Ms. Dupain-Cheng’s school. He was sure that she would learn about it and apply quickly. Ms. Dupain-Cheng had seemed like an ambitious student from what he had found so far, so the offer of studying in America would be tempting. Plus if she was as clever as she seemed, based off her actions as Ladybug, then he was sure she would want to come and try to meet with Batman. It didn’t take long for Marinette’s application to cross his desk. As he approved her application and typed up her acceptance email, he smiled and began the next phase of his plan.
—————
Bruce knew that Marinette would be very concerned if he approached her about being Ladybug outright. It would be best if she approached him. And here was the problem. She wouldn’t approach him, she would only approach Batman. So he needed to have her figure out that he was Batman. He didn’t want her to transform into Ladybug and look around Gotham for him. That could cause people back in Paris to figure out her identity, if Ladybug appeared in Gotham at the same time as Marinette. And if Hawkmoth figured it out, that would be horrible. And if Marinette went looking for Batman in her civilian form, it could be really dangerous. Instead, Bruce and his sons were going to make it painfully obvious who they were. They would leave all their equipment out in plain view, all their case files out, he was even going to park the Batmobile outside in the driveway (out of sight of the gates of course, he doesn’t want anyone but Marinette to find out his identity). Short of walking around in their costumes, they would do everything they could.
——————-
Bruce’s sons were excited. They didn’t have to be careful about their identities around her which was a plus, and after learning that Marinette fighting Hawkmoth with only Chat Noir for consistent help, they were more than ready to help them with the Hawkmoth problem. They had also made bets on how long it would take her to figure it out, and which member of the family would be the one to give it away. They were ready for Marinette to arrive.
———————
Marinette had arrived about a week ago, and Bruce’s plan was in full effect. But, surprisingly, Marinette hadn’t figured it out. She spent most of her time out, walking around Gotham. She had told the Waynes that she was familiarizing her self with the city and also gathering inspiration for her designs. In reality, she was focused on finding Batman. So focused in fact, that she missed all the clues that the Waynes were leaving her. She had walked right past the Batmobile, hardly giving it a second glance. She had picked up some casefiles sitting at the dining table, and instead of reading, or even just looking at them, she just handed them to Bruce and finished setting the table. She had walked in on Jason cleaning his guns in the living room, and instead of commenting on that, just sat down and turned on the TV. At one point, she even came into the gym and found Dick doing an acrobatic routine that only Nightwing would be able to do, all while Tim and Jason were sparing, and Damian was sharpening his sword. They were sure this would get her attention. But Marinette didn’t even notice. She just got on a treadmill, put in her headphones and started running. They boys just stared at her. They were shocked that she could be so oblivious.
————————
While Marinette was out walking around Gotham, looking for Batman again, the Batfam was having a meeting at the manor. They couldn’t believe that Marinette hadn’t figured it out yet. At least Bruce could definitely prove that his secret ID was better than Clark’s. Marinette’s been living with him for months now, with them actively trying to reveal their secret to her, and she still couldn’t figure it out. They were running out of ideas and time. The program ended in a few weeks and they had done everything they could think of. Except for one thing. They hadn’t thought they would have to be so obvious, but it was clear that Marinette would figure it out any other way.
———————-
So, that is how they found themselves coming up from the Batcave, in full costume, making a lot of noise to draw Marinette’s attention as she sat watching TV in the living room. Marinette came around the corner and looked at them. Marinette’s eyes grew wide, and she just stared. The Waynes were sure she finally figured it out. Finally, she broke the silence, saying “Nice costumes guys! You look just like the real Batfam. Nice attention to detail!” Then she just went back into the living room, leaving the Batfam frozen in disbelief.
——————–
Bruce decided enough was enough, and the family went into the living room, still in costume, and told Marinette their secret directly. She was pretty surprised. She had been so consumed with looking for Batman around Gotham, she never even thought she might be living with him. The night continued for a long time after that. Marinette revealed her secret and the Waynes revealed they had known all along. They told her that they had seen her using the horse miraculous to go back to Paris for an akuma battle, which that may not have been how they figured her out, but they had seen that too. After all the reveals were done, the group spent the rest of the night focused on Hawkmoth and how to track him. Tim got to work immediately and was sure he would have an answer soon, though it may be after she went back to Paris. The rest of Marinette’s time in Gotham was spent training how to fight properly, and how to find better places to transform. Marinette soon went back to Paris, armed with better fighting skills, and the knowledge that she now had Batman as an ally in the fight against Hawkmoth.
