Sometimes Ladybug was temporarily joined by Adrien Agreste or Cat Noir was temporarily joined by Marinette Dupain-Cheng. Yet sometimes both Ladybug and Cat Noir couldn't be there, but Marinette and Adrien could. A partnership would be formed with or without memories of it, and the first time was without being able to have memories, as all that they could do was grow and refigure things out, together.
Admittingly, their first time as civilian heroes together ended up involving a lot of running away from an Akuma with a teensy bit of fighting before they were able to transform and fight by each other's side as Ladybug and Cat Noir.
Their second time was a little different.
The ceiling opened up above them and the chandelier came crashing down along with a recent introduced Akuma, and Marinette found Adrien by her side. When the ceiling started collapsing, he'd dove off of the cat walk and joined her behind some over turned chairs, as he wasn't the one to have moved when the Akuma started destroying the building.
"I am The Fashionista, the true one, and I'm tired of being put down, when I should be given a seat of honor at the fashion shows, not forced to be part of the wait staff when I am allowed in." Adrien looked around; there was no place to transform right now, and fold up chairs made awful shields.
"Marinette, we can't stay here." He reached down for his friend's hand, "We need to deal with that Akuma, so that Ladybug could get here."
"And Cat Noir, he needs to come here too." Marinette finished, causing Adrien to really look over at her, perhaps she really did notice Cat Noir and cared enough about him to never consider him just a sidekick. He'd heard that argument before tons of times, and very few remembered that Cat Noir was Ladybug's partner, not her sidekick.
"So, follow my lead, for right now." Adrien stood up, wondering if this was a terrible idea as he lifted up a fold up chair and threw it straight at the Akuma, before grabbing Marinette's hand and booking it away from the audience in the room.
"Okay." Marinette answered; it was only when they stopped behind a wall that Adrien paused to really consider the warmth of his friend's hand and just how soft it was. His face turned a light shade of pink as he stared beyond the wall, feeling Marinette's hand relax in his as she thought too.
"If we can lure him out of the room, the others can find time to escape." Marinette spoke up as she stared at the room.
"Where are you, Filthy Model?" The voice of the Akuma crowed as Marinette searched for the right way to convince the Akuma to leave the room entirely.
"How about we go to the dressing rooms? Make sure he sees you." Marinette squeezed Adrien's hand one last time, and he trusted her instincts as she rushed off, moving quickly and not pausing long enough to see if he was going to follow her and trust her plan entirely.
"Hey, Fashionista?" Adrien called out, "You wanted me?" Marinette had already disappeared into the back, and Adrien was eager to follow.
"The Fashionista, Agreste!" The Akuma hissed.
"Then you'd have to catch me first!" Adrien took off running, surprised when he made it to the changing rooms to encounter Ladybug instead of Marinette, but he figured that she'd finally arrived and brought Marinette to safety.
"I'll take it from here. Go hide." Ladybug commanded, and Adrien was quick to follow her command, if only for a chance for him to transform to fight alongside Ladybug.
