Spoiler: Audition 2x01

Disclaimer: I don't own Glee.

No one understands them like they understand each other...well except Brittany. The 3 of them have been best friends since the 4th grade so it to them its nothing out of the norm. Fighting and insulting each other is like exchanging notes with each other. They would be on the ground exchanging punches at 2:00 and laughing and talking by 3. That was just how they worked. It was also what happened when two people that were so much alike were best friends. That's why when Mercedes gave them a weird look when they walked into the choir room they were honestly confused.

"What?" Quinn asked raising her eyebrow as Santana untangles their arms and makes her way to the second level of the risers to take a seat, Brittany follows.

"You guys. You and Santana... you guys were just arm locked." Mercedes said turning to look at Santana then back to Quinn.

"Arm locked?" Kurt asked frowning as he came to take a seat next to Mercedes. "What is 'arm-locked'?"

Mercedes ignored the hand quotes he made as she rolls her eyes. "You know arm-locked?"

Mercedes loops her arm through Kurt's as an example. Kurt looks down and nods.

"Oh. Arm lock sounds like a wrestling move." Kurt said shrugging as Mercedes rolled her eyes and turned back to Quinn who was smirking.

"Yeah so? We always walk like that." Quinn said shrugging as she took a seat in front of Santana on the first riser.

"True... but you guys were just trying to rip each other apart a few hours ago." Mercedes said frowning.

"Yeah I know. Thats just because she's a bitch."

"I may be a bitch but you're a snitch!" Santana snapped. Quinn rolled her eyes.

"Oh I'm sorry. No one told you to get a boob job when you clearly know its against Cheerio rules." Quinn said over her shoulder.

"Coach wouldn't have noticed if you would've kept your mouth shut!"

"Because I'm sure she wouldn't have eventually noticed that your chest was twice as big this season."

"Yep the same way she didn't notice that huge beach ball of a stomach growing under your uniform before I told her... oh wait. I didn't did I?"

"Oh! By the way! Congratulations on being back on the cheerios!" Tina said with a smile,quickly jumping in.

"Thanks Tina." Quinn said with a grin.

"Yeah now if she could just keep her legs closed maybe she can stay this time." Santana said with a smirk. Quinn growled and whipped around to face her with a scowl. Santana just grinned.

"S be nice." Brittany mumbled. Santana rolled her eyes as Quinn smirked and made a whipping motion.

"Kiss my ass Fabray!" Santana snapped but the corner of her mouth gave away to a smile.

"Fuck you Lopez" Quinn said back with a smirk. Brittany frowned and leaned towards Santana.

"I thought you said only I could do that now?" she whispered. Santana and Quinn exchanged a look before they both fell into laughter. When Quinn regained her composure she turned back to face Mercedes.

"I'm sorry what were we talking about again?"

Mercedes face-palmed as Kurt laughed.
