Chat emerged from his hiding place and scanned the area. The students were still crowded around the unconscious Felix. He joined them as Nino shrieked.

"Woah! Chat Noir is here!"

He wrapped an arm around Chat's shoulder and grinned widely. "Yo! If my friend Adrien were here, he'd be so stoked to see you!"

Chat laughed nervously. "Right."

Ladybug abruptly joined the classmates, causing Alya to shriek this time.

"OMG!! Ladybug!" she exclaimed, whipping out her phone. She held it in front of her and pressed the "record" button.

"Hey, Ladybloggers! I'm here at the scene with Ladybug and Chat Noir!" she squealed, pointing the camera at the two heroes.

Chat smirked and flexed while Ladybug just rolled her eyes. A gasp was heard from Nathanael.

"H-He's getting up!" the red-haired boy shouted frantically.

Ladybug quickly turned around and saw Felix coming to. He stirred. Ladybug quickly glanced at Chat Noir.

"Grab him and take him to a room before he becomes aware," she instructed.

Chat nodded and grabbed Felix by the waist. He and Ladybug sprinted to an empty classroom and sat Felix in a chair. Chat quickly tied his hands and feet together with duct tape. Felix soon groaned and his eyes slowly opened.

"Here's a tip," Chat said cheekily. "Don't mess with any girls' boyfriend."

Felix growled and rubbed his head. "No kidding." His eyes then glanced over at Ladybug.

She waved. "Hiya."

"Hi," Felix muttered.

Ladybug strolled over to Felix and patted his head. "You want some ice for that bruise you have there?" Felix winced from the pain she unknowingly inflicted.

"That'd be appreciated," Felix replied.

Ladybug nodded before walking out of the classroom. As soon as this happened, Felix raised an eyebrow at Chat.

"Does she know?"

"What?" Chat asked with a tilt of his head.

Felix groaned in annoyance. "Your secret identity. Does she know?"

Chat gasped. "Oh! No. So pretend like you have no idea who I am."

"No problem," Felix replied with a roll of his eyes. "I swear you're smarter as Adrien."

"Hey, shh!" Chat whispered harshly. "I don't want her to find out!"

"Find out what?" Ladybug suddenly asked. Chat jumped in shock. He scratched the back of his head and glanced at his partner who was walking in the room with an ice pack.

"Oh, uh, nothing. You don't know anything!" Chat exclaimed with a sheepish smile.

Ladybug smiled. "Relax, kitty cat. Trust me, I would much rather prefer not to hear what you two boys were talking about."

Felix produced a noise of disgust while Chat smirked.

Ladybug walked over to Felix and handed him the ice pack. He placed it on his head. Ladybug then leaned up against a desk and crossed her arms.

"First things first," she began. "Why were you trying to run away?"

Felix's eyes frantically darted around the room. "I don't have to tell you anything."

"Tell us," Chat demanded, glaring at Felix.

"Nope," Felix said. "Now untie me or else."

"Or else what?" Ladybug asked with a challenging smile.

Felix was about to say something when he clamped his mouth shut. His eyebrows furrowed with anger and for the first time, he actually showed some emotion.

"Now talk," Chat said, crossing his arms.

"Fine," Felix said. "But you have to untie me."

Ladybug widened her eyes. "What? No way!"

"Come on!" Felix growled. "That's the only way I can explain myself."

"The only way?" Chat asked, narrowing his eyes.

Felix nodded.

Chat glanced at Ladybug. They were both unsure if Felix would honor his word, but they had to make a move. Ladybug sighed loudly and walked over to Felix. She began untying his hands while Chat untied his feet.

"But if you try to escape, I will hurt you. Bad," Chat threatened, sending Felix a warning glare. Just because Felix was his supposed brother didn't mean Chat wouldn't fight to protect the ones he loved.

Ladybug finished untying Felix and stepped back, getting her yoyo ready in case he tried to retaliate.

Felix stood up calmly and rubbed his wrists. "Much better," he murmured.

Ladybug raised an eyebrow as the boy was taking the situation quite calmly.

"Okay, explain," Chat pushed.

Felix held up a hand. "Hold on."

Chat groaned impatiently while Ladybug face palmed herself. Felix finished tending his chaffed limbs and cleared his throat.

"Okay," Felix said. He waved his left hand over a silver ring on his right hand. He then raised it into the air, and it glowed purple.

Ladybug and Chat both watched the scene unfold in shock.

A black creature flew into the ring and Felix began transforming into... Chat Noir?!

Chat's mouth hung wide open as he watched Felix turn into another Chat Noir, except there were a few details that were included on his outfit.

When the transformation was complete, Felix smirked. "Surprise."

"B-But," Ladybug stuttered, pointing between Chat and Felix. "Why--How--"

"You copy cat!" Chat exclaimed. "One is bad enough, but two?!"

"Actually, you're a copy of me," Felix defended. "Just saying."

Chat pouted while Ladybug watched in shock.

"How is this even possible?" she asked incredulously. "Two of you can't exist."

"It's a long story," Felix replied. "But, in short, our Earth had an akuma that could control the universe. Basically, by ways that are a mystery even to me, they sent me to your world."

Ladybug gasped while Chat ran over to Felix. "So that means your Earth has another Ladybug?" he asked desperately.

"Uh, yeah?" Felix replied. He then hissed defensively. "But she's mine."

Chat sulked while Ladybug absorbed the information. How was it possible? She had no clue. But she had to get Felix back to his Earth, somehow.

"We can try to help you," Ladybug offered.

"I don't know if you can, honestly. Finding the Ladybug and Chat Noir of this Earth wasn't hard, but now lies the real task. How am I supposed to get back?"

"Maybe we could find your Earth's doppelgänger here and get them akumatized?" Chat chimed in.

Felix shot him a glare. "That's a terrible idea."

"Maybe we could..." Ladybug said, thinking. "Contact Hawkmoth?"

"We just need to find out where the heck he's hiding," Chat mumbled.

Felix shook his head sadly and sat down. "It's no use. I'm stuck here for good. I'll never be able to return to my Earth."

Ladybug sighed sadly. "I'm sorry," she mumbled. "But I honestly don't know how to fix this. I wish I could."

Felix stood up and took off his ring, releasing his transformation. "It's okay," he muttered. "It's not like life was great for me back home anyways."

Felix moped out of the classroom while Ladybug and Chat shared a sad glance.

"Poor guy," Ladybug mumbled.

"Yeah," Chat nodded, his ears drooping. "I kinda wish we could help him."

"But until we encounter an akuma that can control the universe, looks like Felix is stuck here," Ladybug said.

"Sounds like his Ladybug meant something to him too," Chat mumbled sadly.

"Yeah," Ladybug nodded quietly.

THE END.
