A/N: Late again. Sorry! I've been busier than I thought recently (it is amazing how much you miss through a four month illness. I swear I'm inches away from drowning in homework, everywhere I look there is more. I'm not joking. I can see my Spanish book as I write this. It's slightly disturbing.) But hopefully I'll be back on schedule soon :) I found this prompt as one of the last to be posted on imagineyourotp (RIP blog) and had a few ideas, hopefully it's okay!

Sorry for any grammar/spelling mistakes, it's been proofread by my tired eyes at quarter to one in the morning XD

Prompt: Imagine your OTP attempted to be sabotaged and broken up by a jealous person who loves Person B. Throughout the day, this jealous person constantly tries to make Person A do stupid things and generically mess up to have Person B get tired of them and hopefully break up. However, the attempts all seem to fail and end up bringing the pair closer than before.

A pair of jealous eyes watched from the corner.

Marius and Éponine were laughing at Grantaire as they exited the café - the man had been going around drunkenly nicknaming every member - so far Enjolras was an 'unwanted onion', Joly was a 'cow-brained goblin', Courfeyrac was 'about as wanted as a plague-infested mosquito', Combeferre an 'unintelligible out of tune piano' and Feuilly found himself named Rover all of a sudden.

All in all, an entertaining afternoon.

Éponine slipped her arm through Marius', and he kissed the top of her head gently. The eyes turned to narrowed slits as the owner frowned deeply.

As I'm sure many of you have guessed, the owner of these eyes is none other than Cosette.

After Marius left her for Éponine about two months ago, she wanted revenge. She wanted her Marius back, her brain still telling her that he loved her, not the street rat.

She began the walk home, it was starting to get cold and the last thing she needed was a speck of dirt on her pristine shoes, or, heaven forbid, a drop of rain on her gorgeous/atrocious ringlets. Clearly, Marius' advice about curly hair had gone in one ear, skilfully avoided her brain and straight out the other.

As she sat on her bed plotting, she thought that she'd simply cause so many accidents hat Marius would begin to dislike Éponine, and come back to her. Yes, that would work, surely?

Marius and Éponine were completely oblivious to her watching them from the window - Marius was lying on a bench with Éponine face down on top of him, her face buried in his shoulder and his hands resting on her lower back. They appeared to be discussing something, although she couldn't lip-read, so of course she had no idea what the subject was.

As they eventually got up to leave (they'd been lying there for about two hours) Cosette followed them. For all her shallow naïvety, she didn't get spotted, and soon found out that Éponine was staying with Marius at his flat.

The next morning dawned bright and sunny, and Cosette's plan took action.

The first thing she noticed was Éponine hanging up some shirts on a communal washing line, presumably Marius'. Waiting until the girl was gone, she carefully took down the shirts and dropped them in a rather large mud puddle directly below, dropping the pegs in there for good measure. Surely he wouldn't want to stay with anybody who muddied his clothing?

Marius came out about an hour later, and spotted the shirts in the mud. "Éponine!" she heard him call, and the girl appeared. "Yep?"

"Would you mind washing my shirts again? They fell in the mud."

Éponine sighed. "I'm so, so sorry. I guess the pegs were a bit dodgy. Do you mind wearing the same shirt again?"

Cosette was sure he'd say no - who wanted to wear the same clothes? She had one flouncy dress for every day of a fortnight - Mondays were blue, Tuesdays were white, Thursdays were yellow, Fridays lilac, Saturdays were red, Sundays cream, and of course on Wednesdays she wore pink.

But Marius just nodded and gave Éponine a reassuring smile. "It's fine, it won't kill me to re-wear something" he said, giving her a kiss on the lips before disappearing inside, Éponine soon following.

Cosette frowned. Why couldn't people just do what she wanted?

She tried several other tricks throughout the day - causing Éponine to trip and rip one of his books, making her drop a paper of his into the Seine (it was surprising how much force you could get out of flapping a shawl around), hiding the scissors after Éponine had used them as if she'd lost them. And each time Marius would chuckle and kiss her, telling her it was okay.

Cosette was not happy.

She'd used up every trick she could think of, and nothing had worked. Time for plan B.

She waited until they were walking to the Café before appearing in front of Marius.

"Hey sweetheart" she said, in a sickly-sweet tone. Marius glanced worriedly at Éponine, who frowned back.

"Missed me?"

"Um, not really, I-"

"Oh don't be silly Marius, of course you missed me."

"Cosette, I really didn't, no offence but-"

"Ssh, Marius" Cosette answered putting a finger on Marius' lips. He pushed it away roughly, taking Éponines hand and squeezing it tightly. Cosette frowned. "Why are you still with her and not me?"

"Because I love Éponine, and not you."

"Oh, you're such a tease! Honestly!" Cosette giggled, going way over the top with a silly, exaggerated hand gesture. Éponine just stared at her. How dare she come back, after Marius broke their relationship?

"Cosette, please just go."

"But I love you! And you love me!"

"Except I don't."

Cosette ignored him, and before he had a chance to protest, she was kissing him passionately. Marius flailed for a few seconds before pushing her roughly away, rubbing his mouth fiercely with the back of his hand.

Éponine took a step forwards. "You did not just go there, bitch."

Cosette smirked in reply.

Éponine took another step forwards. "Aww, is daddy's little girl sad because the big handsome man doesn't love her anymore? Oh dear, my heart just broke" she said with a scowl. "Just get over the fact that not everything the light touches is your kingdom" she added, looking like she was about to tackle the other girl.

Marius held her back. "You heard her. Cosette, I don't want you in my life anymore, just leave us alone."

"But I love you!"

"But I don't love you! Especially with your hair in those ridiculous curls!"

Cosette looked at him, sticking out her lower lip. Obviously she was used to putting on the cutesy-little-girl act to get what she wanted. But Éponine was having none if it. She got out of Marius' grip, walked up to Cosette and punched her straight in the face, knocking the girl out.

"Well, that took care of that then."

Éponine turned around and looked at Marius. "You have no idea how much I've wanted to do that."

Marius smiled at her. "Come here" he said gently, taking her by the waist and drawing her closer, pressing his lips gently to hers. Éponine's hands found their way to his chest as she leaned up and kissed him back, smiling into the embrace.

"I love you Éponine, no matter how many shirts and books you ruin."

"I love you too Marius, no matter how many air-headed blondes chase after you."

At the exact moment they resumed their embrace, Cosette woke up on the floor. She took one look at the state of her dress and promptly fainted again, leaving Marius and Éponine restraining giggles with raised eyebrows.

Not every blonde bitch can ruin somebody's day, right?
