(I'm sorry if this story's a bit confusing as well. Nathalie/Gabriel means Nathalie in Gabriel's body and Gabriel/Nathalie means Gabriel in Nathalie's body) (set in season 3)
Nathalie watched as the villain approached the mansion "transitionator, go after ladybug and chat noir, not Gabriel!" Hawkmoth commanded from his lair.
No matter how many times he told transitionater to stop he kept getting closer until he was at the door, he kicked it down and searched the house for Gabriel.
"He's not here" Nathalie tried to get his attention, he took out his blaster and aimed it at Nathalie, he shot her but it didn't seem to do anything until everything went white.
When she woke up she was in the lair "what happened?" She said to herself "why is my voice so deep?" She started to freak out.
She looked down and realised she was in Gabriel's body "he was the closest person to me" she sighed, she exited the lair and went to the hallway where she found herself/Gabriel.
"Gabriel, are you in there?" She said prodding her unconscious body "Where am I and why am I dressed like Nathalie?" He groaned getting to his feet.
They looked at each other confused "Gabriel?" "Nathalie?" They said simultaneously, they stared at each other speechless.
"Me?" Gabriel was confused
"Transitionater swapped our bodies. We don't have time to deal with it now, I have a meeting in ten minutes, you'll have to go as me" Nathalie explained.
Gabriel was shocked he had to leave the house. He got in the car and gorilla drove him to Nathalie's 12 o'clock meeting at Audrey bourgeois office.
Audrey's receptionist smiled and told Gabriel/Nathalie to go straight into the meeting room. Audrey looked Gabriel/Nathalie gup and down not knowing it was actually Gabriel.
He sat down
"Do you ever wear anything else?" Audrey snapped, Gabriel was shocked at Her attitude but he just smiled "Gabriel designed this suit especially for me"
"Anyway, you wanted to borrow some of my models?"
They went through the possible applicants and after many hours of shouting They finally agreed on two models "Great, you picked my two worst employees" Audrey put on a fake smile.
They signed a few pieces of paperwork in silence and then Gabriel got to leave, he got in the car and gorilla drove him to the next meeting "Another meeting?!" Gabriel was surprised. Gorilla nodded and showed him Nathalie's schedule "1pm meeting with the tsurugis, 1:30 meeting with jagged stone, 3:00 meeting with the dupan-chengs, Wow that's a lot of meetings" he read it out.
He got out the car and rushed into the bourgeois hotel restaurant where miss tsurugis was waiting.
After 4 hours of meetings
Gabriel sighed as he walked through the door "how do you do this?", he slumped into Nathalie's chair and stared at Nathalie/Gabriel at the podium. She was looking at the screen inquisitively "Sir I was looking at your designs and I have a few suggestions, but anyway how was your day?", Gabriel looked at her tiredly "Is Audrey always that mean?"
Nathalie/Gabriel looked up from the screen "Yeah since the argument at the fashion show we just don't get along"
"What argument?"
"Audrey wanted front row seats but Adrien wanted Marinette to sit in the front row so I had to make her leave but not before she tried to fire me, Chloe also has that problem" Nathalie/Gabriel laughed
Suddenly there was a flash of light.
"What was that?!" Gabriel looked around "I'm me again!"
Nathalie sighed "I'll get back to work" she stepped of the podium
"Actually, you can have the day off, you work way too hard"
"Sir, I don't think that's a good idea" Nathalie insisted
"Go to the Eiffel Tower or go to the park, I'll get gorilla to get Adrien from school" he said pushing her out the door
"I guess I have the day off"
