"Nope".
"But Beca!" Jesse whined. "It's a costume party! That entails wearing COSTUMES".
"That's not happening. It is a riff-off and it's not even Halloween".
"But I promised Benji-"
"Nope".
"But-"
"No".
"Bec-"
"Nuh".
"But Bec-ca!"
"The answer is still no".
"Fine!" Jesse sulked, throwing his bottom lip out like a child. "You're mean".
(Good Lord, she was dating a six year old.)
"You are the worst person in the entire world", Beca informed him, as she self-consciously adjusted her skirt (Beca Mitchell was wearing a skirt). "Like, seriously".
"You look great", Jesse pronounced, his eyes gleaming.
"You are so weird". She frowned slightly, adjusting her skirt. "Seriously. This is the worst idea you've ever had in your entire life".
The Breakfast Club was their movie. Of course they had to dress up as two main characters for their first Halloween as a couple. And of course she was dating the biggest nerd in the history of life itself. Of course her nerd would be the one to suggest it.
And her nerd was the reason she was wearing pink.
"Who the hell are you two meant to be?" Fat Amy questioned. "I mean, I get that Jesse's meant to be a hobo-"
"Claire and Bender". Beca rolled her eyes. "We're meant to be Claire and Bender".
"Couples costumes are totally hot", Stacie pronounced.
"Couples costumes?"
(Of course it would be just her luck that Aubrey Posen and Chloe Beale appeared at that moment. The stars were aligned against Beca.)
"Hey Bec!" Chloe said brightly, hugging the tiny brunette in an embrace that was borderline harassment. "Pink suits you; you should wear it more often".
"You're hilarious", she deadpanned.
"What did I hear about couples costumes?" Aubrey repeated. "You wear couples costumes but you find it impossible to don a pair of angel wings for Valentine's Day?"
(Beca revolted against Aubrey's Valentine's Day getup. She refused her Rudolf nose and antlers. And she did not dress up for Halloween.)
"Yeah, and why is Jesse dressed as a hobo?" Chloe frowned slightly, and Fat Amy started to chuckle. "What?"
"Meet the couple wearing couple costumes". Cynthia Rose pointed to Beca, before finding Jesse mingling with the other Treblemakers. "Because they have a movie and everything they've come dressed as the characters!"
"Jesse is the worst person in the world", Beca said quietly, and Chloe actually squealed in delight.
"First and last time", Beca said warningly, raising her voice so that Jesse could hear her.
"Yes dear", Jesse said loyally, coming towards her and wrapping his arms around her waist. "Did I mention how much I love you for doing this?"
"Not nearly enough".
"Well I do. I really love you, Becs".
"You two are the cutest couple I've ever seen", Stacie declared.
In the next year, her boyfriend seemed to forget the threats she had made. Because when he brought up the topic of matching costumes, she just glared.
"Happened once, never happening again".
"Yeah it will".
"Nope".
"Beca!"
"Not happening. At all. Ever".
"Fine!" Jesse sulked.
(If that was how she wanted to play it, then he could top her.)
"You have got to be kidding me".
Beca's jaw dropped, as she entered the Bellas rehearsal space.
"This is such a great idea!" Fat Amy enthused, strolling towards her wearing a Wonderwoman costume.
"Jesus Christ, what the hell happened in here? God, you're two minutes late-"
"Jesse told us your ideas!" Stacie said brightly from where she was filing her nails. "And we think it's a great idea, I've been waiting to wear this!"
She too was wearing a Wonder Woman costume, but Beca didn't even care.
"My ideas?"
"He said you came up with it together", Cynthia Rose clarified. "Group costumes!"
"Yeah!" Lily said brightly.
"I'm going to kill him".
And that was how she found herself wearing a Catwoman costume.
(Aubrey Posen was just going to drop dead.)
"We all look great!" Benji said brightly.
"You're gorgeous", Jesse whispered to Beca, wrapping his arms around her tiny frame.
"You suck as a person".
"You are kidding me", Aubrey voiced, taking in Beca's outfit with bulging eyes.
"Hello Aubrey, nice to see you".
Aubrey turned to Chloe, a mixture of disgust and horror. "She revolts against every costume idea that we ever had, and yet she's happy to parade around as Catwoman?"
"I am not happy", Beca informed them with a glare. "Stupid freaking Jesse. I hate him".
"No she does not". Stacie shook her head, grinning at the way Jesse's arms were wrapped protectively around Beca (because she had won the bet against Fat Amy in their freshman year, and she would hold that against the Australian for the rest of her natural life).
"Why are there multiple Wonderwomans?" Chloe asked curiously.
"Because Stacie and Fat Amy spent three days arguing and in the end compromised". Beca shrugged. "That's why Lily is also Catwoman".
"I'll make it up to you tonight", Jesse whispered in her ear, and Beca shivered (not just from the cold).
(That night, Beca decided that maybe she didn't hate Halloween that much.)
Maybe Beca didn't hate Halloween that much. The excitement on her daughter's face as her daddy called her a princess, emerging from her bedroom as Cinderella. She loved the little girl's laugh, and she loved her son's cheesy grin as he emerged as Superman (he looked so much like his father).
And she didn't even care that much that her husband made her dress up.
Because he totally made up for it.
