Liam was walking around the school after finishing his lunch when he saw someone in Miss Bustier's class.

"Max," Liam whispered to himself. Max was turned away, trying to hide that he was in the room. His arm movement implied that he was fiddling with something. Liam opened the door and walked in.

Max jumped and turned, dropping something on the floor. "Oh! Hello, Liam. You finished lunch early."

"What are you doing in here, Max? We're not allowed in the classrooms outside of the lesson time."

"Oh, I was just looking for some of my things." Liam began walking towards Max and saw what he dropped on the floor, pointing at it. "Oh. Urm, this is..." Max picked up the object. It had a propeller with a blue blade and a black shaft with white stripes on its head. It also had a transparent blue tactile sensor, a gray face with a button that has a blue heart engraved on it, a turquoise screen that could be a face, and two blue ear-like round sections on its sides that had a white outline and a musical symbol on the center of each ear. "Liam Rejeter, say hello to Markov!" Max opened 'Markov' and placed a CPU labeled Markov 1.2 inside of it. This caused 'Markov' to boot up and the turquoise screen generated two black dots and the propeller started spinning, allowing Markov

"Max?" Markov said. "What's going on?"

"Markov, I'd like to introduce you to someone. This is Liam Rejeter."

Liam's eyes observed the room. "Uh, hi?"

"Hello, Liam Rejeter!" The robot replied. "I am Markov, Max's best friend!"

"Well, I'm Liam Rejeter."

"I know a lot of Max's friends, Liam. Max showed me the photo of his classmates. You are not in it."

"Markov," Max explained. "That photo was taken before Liam joined our class. He is a very important person, for his father is the president of France."

"I see. It is very nice to meet you, Liam."

"Er, I'll be honest, Markov," Liam answered. "I'm a bit weirded out by this. It's something new. I mean, are you a robot?"

"Yes. But I am self-sustainable. Max created my base programs but I have been developing on my own."

"I think I can tell. You show emotion in your speech."

"I can show multiple emotions. I truly love Max."

"You two do seem like good friends."

"Best friends." Max corrected Liam. "But I don't think the rest of the class are ready to experience Markov yet."

"I understand. There are things that people keep secret until they're ready. I won't say anything. I promise."

"Thank you. Come on, Markov. You're in need of some repairs."

"Don't you want to play your game?" Markov asked. "I finally worked out all the bugs and the game could be ready for release by Spring."

"Markov, we can't use Ladybug or Cat Noir without obtaining permission from the people who own their likenesses."

Liam tilted his head up. "You're looking the owner's brother! He bought them shortly after I was born!"

"How?"

"Ladybug and Cat Noir are supposed to over five thousand years old. He purchased all rights to them and a lot of other heroes over all their appearances. If I ask him, he may let you use them."

"Oh, thank you, Liam! Would you help us test out what's been done so far?"

"Sure! Where do we go?"

"Adrien's Mansion."

"Great Stuff! I'll head over there after I collect something from home! After school, of course!"

At the Agreste Mansion, Liam, Max, Kim, and Adrien were in Adrien's room testing Max's game. It was a 2D platforming game with Ladybug and Cat Noir as the main characters. The duo had been given some slight alterations. Ladybug's hair was in a bun and colored black, except for the hair in front of her ears, which was white. Her suit's feet were black up to her shins. Cat Noir was given furry forearms, ears and his eyes were changed from green to yellow. Liam, Kim, and Adrien played to test for technical issues while Max jotted down the issues they found.

"Ladybug's yo-yo attaches to points and keeps going till she lets go," Liam said.

"Got it," Max replied.

"Everytime Cat Noir hits someone, blood comes out," Adrien stated. "I don't think that would pass in a game for kids."

"I'll see if we can get that removed."

"Question, Max," Liam asked. "My brother also owns some other likenesses that you could use. Would you like to see them?"

"Such as?"

"Those heroes that showed up a few weeks ago. Minus Knightowl."

"They would be great to use but the idea is to keep it as Ladybug and Cat Noir. We're not even using any akuma villains. Nathaniel's creating some new ones."

"Oh, well." The game finished. "We're done already?"

"Yeah. At this rate, the game will be ready by spring!"

"Nice one! I'd like to pre-order."

"Me too!" Adrien added.

"Ditto!" Kim shouted. The four boys laughed.

"Can I just say thank you, Liam?" Max asked.

"Your very welcome, Max!" Liam replied. The teens kept playing the game, then switched to another one, then Liam pulled a game out of his backpack. "This game is rated M for mature but I've already completed it twice!" Liam showed the three the game. "LA Noire. Solve cases as a detective. Set in the 1940's and my favorite feature: you can set the game to play in black and white." The boys took interest and they spent most of the evening playing games. Eventually, Max and Kim were ready to leave. Adrien saw them out but Liam had fallen asleep.

"Bye guys!" Adrien shouted.

"See ya!" Max and Kim shouted back. Adrien closed the door and went to check on Liam. When he got back into his room, Liam was gone and the window was open. Plagg emerged.

"He's a sneaky one, isn't he?" The kwami joked.

"Yeah," Adrien replied. "Real sneaky..."
