Nadja Wintergreen was one of the best figure skaters. Even Viktor thought so and so did Yakov their trainer. Untill it turned out she cheated on the last Grand Prix and got excluded. Since then, her little sister, Danika Wintergreen was the star among the female skaters. And Nadja hated her. She was the annoying little sister in every sense of the phrase. She easily surpassed Nadja and now she was about to win the Finals despite Nadja's every effort to keep her away. If she couldn't win, then neither will her little sister: She ruined her blades in the last moment, she sent her blackmailing messages anonymously, she terrorized her at home, she even beat her up, twice, no thrice, but the little bitch just got up and went on. To make things worse, both fell in love with Viktor, though he suddenly left and dropped off of the surface of the Earth (only to later reappear as the coach of a Japanese figure skater), and Nadja, of course blamed Danika for it. The girl just shrugged it off and went on building her career, namely getting into the Grand Prix Finals. That's when Nadja had enough and heard Hawk Moth's sweet promise and became Ice Star.
"So, my darling little sister. What will you say, when I freeze you and the rest of the world into icicles?!" Nadja said viciously, then spead up, jumped and twirled, making icicles shoot out of her skates towards Danika. Landing, she expected to see her sister frozen, however three superheroes were there, protecting the skater.
"You seem to be a little frozen," Chat said grinning. "You could go to the corner, it's 90 degrees there." That earned him two loud smacks from the two female heroes and a couple of glares.
"I'll freeze you and take your miraculouses after I have dealt with my sister!" Ice Star spat.
"Sorry, but no," Bunny said picking the younger Wintergreen up and leaping away to hide her.
"I'm sorry," the woman silently said as the blonde heroine placed her in front of the Dupain-Cheng bakery. "My sister's hatred towards me caused you trouble."
"Oh, no worries! This is our job," the white rabbit winked and leapt back to the arena, where Chloé was silently weaping at the feet of a frozen Nathanael, hidden from Ice Star, who was currently engaged by now four heroes.
"Come baCK YOU SNEAKY CAT!" The akuma spat, chasing Chat Noir, occasionally jumping and shooting icicles in all eight directions. Bunny Decided to make a clone who helped out in the fight, while she stayed back and sneaked next to Chloé.
"What happened?" The heroine asked.
"He saved me," the mayor's daughter sniffled. "And now he's an ice statue." Bunny merely used the powers Kurama gave her and swiftly melted the ice around the tomato haired boy, who collapsed into Chloé's arms, shivering.
"Now go and warm up," she said. The couple nodded and hastily left while Bunny went back to the fight scene, making the clone disappear. "So what's up?" She asked Ladybug, Rena Rouge and Carapace, who were standing by the side, watching a grinning Chat playing tag with a frustrated Ice Star.
"Oh, just waiting for our kitty to get bored," Ladybug shrugged.
"He's been playing this for a while now," Rena added flatly.
"Though Ice Star seems way more tired," Carapace commented.
"Come. BACK!" The woman roared still leaping, but still not catching Chat. Even the icicles she shot from her skates didn't reach the cat.
"Well then," Ladybug sighed getting bored. "LUCKY CHARM!" And in a few seconds she got a candy cane. Blinking, she looked around.
"Oh come on! I was still playing!" Chat whined. Realising her job, Ladybug leapt, snatching off the cat's belt tail, tying it to the cane and threw it towards Ice Star's skates. The cane got caught up in the blade, making the skater trip and fall. Chat Noir hastily broke the blades with his baton. An akuma catch and a 'Miraculous Ladybug' chant later, Nadja Wintergreen stood in the place of Ice Star.
"Where is my sister?" She asked, before the heroes could fist bump.
"At the Dupain-Cheng bakery," Bunny replied.
"I'm actually here," said Wintergreen appeared from behind the seats. "I came back after a while to see how the fight went on."
"You," Nadja spat. With a scream she leapt towards her sister, but Bunny and Carapace stopped her from doing any actual harm. "You ruINED MY LIFE! I hate you. I hate YOU! All I ever wanted was a little sister who admired me, but all I got was a bitch who mocked me!" A silent, fat tear trickled down Danika's cheeks and her lips thinned.
"You lost that sister the moment you first terrorized me and ruined my blades at the last moment," the girl said coldly. It made Nadja's breath hitch in the negative way. "I thought so much of you, старшая сестра*. Not even the fact that you cheated made me think less of you. But the fact that you started beating me up physically, mentally and in soul, that made me change my mind of you." Nadja's lips thinned and she spoke.
"Well, you still ruined my life with your talent, младшая сестра**," she spat. That's when the police's sirens could be heard and the officers entered. It turned out that Nadja was wanted in Russia for abusing her sister. As the police brought her away, Danika yelled one last sentence to her sister:
"Despite everything... я люблю тебя***!" Nadja hearing this visibly shuddered and looked back, her face bitter, eyes teary.
"I'm sorry for what happened," Rena said and the other heroes nodded along.
"Do you think she will be happier if I visit her in jail?" Danika asked, voice tired.
"Definitely," Ladybug said warmly. "You are her sister after all." Danika sighed then nodded her agreement. Soon the heroes left, after they had made sure the figure skater was back safe in her hotel. No need to say that the next day, they repeated the Grand Prix Finals and Danika Wintergreen won the gold medal to Yakov's great pleasure.
