Summary: AU. In a world where Marinette never became Ladybug, Adrien never became Chat Noir, but Nathanael was the one chosen to wield Trixx, and faced the Akumas alone, as well as Hawkmoth. And while Ladybug's yo-yo was once used to get rid of the Akumas, it wasn't the only one. When Nathanael isn't feeling well one day, feeling absolutely terrible, and despite his health state, fights and beats an Akuma, and then passes out midair as Volpin.... And onto the roof of a certain concerned blunette.

Rinku: Let it be known that I am not a doctor!

--------------------

Marinette could only gape at the unconscious body laying on the floor of her roof.

Volpin. The Hero of Paris. Unconscious on her roof.

It took a few seconds for her to realize that his chest was heaving. Taking deep breaths. Quicker than normal. Much quicker.

She quickly kneeled beside him, noticing his face was flushed, his orange hair was sweaty, his fox ears were drooping. 

She placed a hand on his forehead, eyes widening when she felt an insane amount of heat. Fever.

She looked up at the sun, it was clearly not helping the Hero. He needed to be moved inside, but she couldn't do it on her own.

'I'm going to get my dad. Don't worry.' Marinette thought, standing up and racing down towards the bakery, where her parents were working.

Once she reached the bakery, she ran to her parents side, who were in the process of taking a batch of cookies out of a large oven.

"Dad, I need your help!" Marinette startled the both of them, making her dad nearly lose his grip on the tray.

"Marinette, what's wrong?" Her mother asked her calmly, as her father placed the tray on the counter, looking concerned.

"It's Volpin. He's unconscious on my roof, he has a high fever." Marinette spoke quickly, making her parents eyes widen.

"Tom, go up with Marinette. I'm going to close the bakery." Her mother spoke, making her way to the entrance of the bakery.

Her father made a gesture, implying he'll follow her. They both ran up the stairs, into their apartment, up to Marinette's room, then Marinette's roof.

Volpin was quickly picked up into her father's large, strong arms. And if it had been any other day, the sight would've been humorous. But the sight could be compared to a sad child in a father's arms.

"Oh my, he's really heating up." Her father muttered.

"We can put him in my bed." Marinette offered. Her dad nodded in agreement, making his way back into Marinette's room carefully.

Marinette followed after she closed the latch, rushing to her bed and pulling back her covers. Her father  carefully lowered the Hero, who immediately curled up into a ball, his fluffy orange tail close to his face.

Both Tom and Marinette noticed his body shake slightly. Marinette quickly pulled the covers up to the Hero's neck, noticing the spiked collar around his neck.

"I'll be right back." Her father made his way down the stairs, with the intention to get a rag.

Marinette could only look at the hero sympathetically and sat down to his right. She couldn't help but look at his furry ears, and wasn't able to resist poking it with her finger, giggling when she saw it twitch. 

She heard two pairs of footsteps walking up to her room. 'Don't worry. we'll take care of you.' Marinette thought, seeing her covers rise up and down.

"How is he?" Her mother asked, placing a tray with a few items on her dresser. Her father had soaked a rag in water, which was placed onto Volpin's forehead, despite the hero laying on his side.

"He was burning up when I found him." Marinette said.

Her mother picked up a thermometer from the tray she had brought up. "Tom, can you move him onto his back?"

Her father gently moved Volpin from his curled position, onto his back, who grunted at being moved. Her father made sure to keep the rag on Volpin's forehead. "This is probably uncomfortable for him, considering his tail." Her father said, noticing the hero shift uncomfortably.

"Oh. I'll just take his temperature quickly." Her mother quickly sat down to the left of Volpin, gently easing the teens mouth open, and placing the thermometer under his tongue. A few seconds later, she heard the beep and pulled out the thermometer.

The thermometer read 100°F. Really high fever. "I'm going to call a doctor. He has a really high fever." Her mother said worriedly.

"What's his temperature?" Her father asked, as her mother placed the thermometer on the tray.

"100°F." Her mother said firmly.

"That's really high." Her father muttered.

"Which doctor? It's starting to get late." Marinette asked, gazing at Volpin.

"I'm sure Mr. Sato is available." Her mother mused.

"I'll call him right now." Her father made his way down the stairs again.

"So, what do we do?" Marinette asked her mother.

"We should try to keep him comfortable. It's worrying that he's still unconscious." Her mother said, removing the rag and dipping it in some cool water, and placing it on the unconscious teens forehead.

Both females heard a slight sound.

A purr.

They both chuckled when they realized it came from the unconscious Hero, who had shifted onto his side, facing towards Marinette.

All they had to do was wait.

----------------------------

It was getting late, close to eight at night, three hours since they had brought Volpin inside. They had since removed the shield from his forearm and placed it on the dresser. 

Doctor Sato examined the unconscious teen and told the Dupains to try to lower the Hero's fever. To keep the teen comfortable. To keep the teen hydrated and well nourished, should he wake up.

Marinette's parents had closed up the bakery, their concern over the hero taking priority. Although, they both had to make some special deliveries for some customers, leaving Marinette to watch over the hero.

Volpin was still feverish, transitioning from feeling cold to hot every few minutes, still curled up on his side. Marinette changed the rag every couple of minutes, working on her homework in the meantime, on her desk. Every few minutes, she would go up the couple of stairs to check on the passed out hero.

---------

He felt hot, too hot. Despite being delirious, he could tell he wasn't home. He could smell lavender, and... cookies? Brownies? Where was he?

He kept his eyes closed, focusing on his hearing. He could hear the sound of a pencil on paper. and someone sighing. His stomach churned, making him groan. He swallowed back the nausea he suddenly felt.

He heard the sound of a rolling chair, footsteps, then the sound of the footsteps going up a set of...stairs?

Having enough of not knowing where he was, he opened his eyes slightly, a growl escaping his throat when he spotted a shadow at the foot of the bed, in his peripheral vision. The footsteps ceased. 

Volpin blinked his eyes until he could see clearly. Becoming more aware of his surroundings, he realized he was curled on his left side, and struggled to sit up right. He didn't even notice the rag fall into his lap.

He closed his eyes at the strain. 

"Hey, its okay. C'mon, lay back down." A familiar, soothing voice made his ears twitch, and he heard footsteps make their way to the side of the bed.

"W-where am I?" Volpin asked, voice hoarse. He finally sat up completely, eyes still closed.

"You're safe. Um, my name is Marinette." The voice said said timidly. Volpin opened his eyes to see Marinette looking at him.

Marinette noticed the hero's slumped shoulders, clearly tired. "Um, are you hungry?"

Volpin tilted his head slightly, moving his gloved hands into his lap, resting his weight on his elbows. "I don't think I can hold anything down."

"Oh. Well, do you want some water?"

Volpin became extremely aware of his sore and parched throat. "Please."

"I'll go get you some." With that Marinette her way down the stairs, and down the hatch, with the intent to get the hero some water.

Volpin closed his eyes and rested his head in his hands.

He could just leave and go home, but that would make him look bad. And it was Marinette that was taking care of him. Marinette.

With a sigh, he waited.
