Chapter 1

Quinn's brow furrows as she watches Sugar chatting to Brittany, her hand flirtatiously running up and down the tall blonde's arm as she murmurs to her in a voice too low for Quinn to hear. They stand in the doorway of the choir room, oblivious to their friend's presence as they giggle and flirt, Quinn wondering what Santana would have to say about this. She doesn't have to wait long for her answer as Santana saunters into the room via the other entrance and, as expected, a dark look crosses her tanned face. Quinn watches as the latina strides across the choir room, sparing the blonde a fleeting glance as she reaches the other girls. Hazel eyes narrow and perfectly manicured brows shoot skywards as Sugar nods meekly in response to something the head cheerleader says to her and wanders over to the chairs with her gaze fixed on the floor. Quinn's jaw drops, she had never seen the rich, spoiled brat back down from anyone so easily before. Santana shoots Quinn a glare that tells her to mind her own business while she leads a sullen looking Brittany to the back row of chairs, the latina sitting inbetween the two other girls as the other members of the club file into the room, Rachel looking rather put out at not being the first to be there. The blonde can hear Brittany murmuring pleadingly, only to have whatever she is say shot down by Santana's furious hiss. Quinn strains to listen for details, the swift kick to the back of her chair informing her that Santana notices her attempts to eavesdrop. The three girls are mostly silent for the rest of glee club, the only sounds coming from them are the occasion creak of their chairs whenever they move and a groan from Sugar when Rachel stands up to sing yet another solo. They are among the first to leave the room at the end of practise, Sugar and Brittany traipsing behind Santana without so much as glancing at each other.

"Britt!" Quinn isn't sure why she shouted after the other blonde, her curiosity must have bested her so she crosses the room to meet the cheerleader anyway.

"You okay Quinn?" the taller girl asks, genuine concern in her baby blue eyes as she studies her friend.

"I was actually going to ask you the same thing" Quinn admits, "You guys seemed...different today. Sugar seems to be hanging around with you guys a lot recently" she adds, unsure of what she's actually trying to ask Brittany. The dancer doesn't have a chance to answer her friend, the sound of someone clearing her throat causing her to spin around and smile sheepishly at an unamused Santana who is standing in the doorway.

"I gotta go Q I'll talk to you tomorrow" Brittany throws over her shoulder as skips across to the latina and Sugar and pressing a gentle kiss to Santana's face, the tanned girl's features softening slightly. The hispanic teen catches Quinn's curious gaze and she turns to face Sugar and Brittany, a glint in her dark eyes.

"Car. Now" she states quietly but firmly, both girls nodding and turning to quickly do as Santana told them, the latina waiting until they are out of sight before giving Quinn her full attention. "What Quinn?" she asks with a sigh. "You've been basically spying on us for the whole of glee club, why are you being weird?" Santana asks with a raised brow.

"I'm being weird? Me? It's you guys that are being weird! What is going on with you guys? Sugar has been following you and Brittany around school for a while now" Quinn states suspiciously.

"So what?" She's our friend" the latina shrugs.

"It seems like it's more than that" Quinn mutters, noticing something she can't quite explain flash in the other girl's dark eyes.

"What? You don't think a lesbian can hang around with another girl without it being something more than a friendship?" the cheerleader asks snarkily.

"That's not what I'm saying at all and you know it Santana!" Quinn scolds. "It just seems like there's something going on between the three of you. I know you well enough to know that you're deflecting right now and all that tells me is that you're definitely hiding something" the blonde adds, feeling pleased with herself as she watches the cheerleader become flustered. "We used to be friends, you used to tell me everything" Quinn murmurs softly.

"I gotta go" Santana grumbles, brushing passed the other girl and striding from the room, leaving Quinn alone in the choir room. She sighs sadly, she had thought their friendship had improved lately, that they were back on track but apparently not. She sets her jaw in determination and vows to find out what is going on.

Brittany glances at her cell phone as it vibrates for the third time in as many minutes. She sighs when Quinn's name glares back at her and she presses ignore, silently shaking her head.

"Santana looks pissed" Sugar murmurs from the backseat. Brittany looks up to see Santana storming across the parking lot and her stomach lurches nervously at the raven haired girl's hardened features. "Quinn needs to learn how to mind her own business" the girl adds.

"It was our fault, we should have been more careful" Brittany sighs.

"I didn't even know she was in there" Sugar argues with a frustrated whine.

"Exactly. We didn't even check to see if anyone was in the room" the blonde retorts. "We should have checked and now Santana is..." she trails off as the driver side door is yanked open, the furious Latina sliding behind the wheel and slamming the door closed. Both girls watch warily as the head cheerleader grips onto the steering wheel so tightly that her knuckles turn white, her eyes closed as she forces herself to calm down. Neither girl speak as Santana clicks her seatbelt into place and starts the car, knowing in that moment what is expected of them. The drive to Santana's house is silent and and tense and Brittany swears she can see her heart beating out in front of her chest, her hands growing clammy while she anticipates what will happen when they reach their destination. The intense nerves she feels can only be matched by her excitement and she knows Sugar will be feeling exactly the same.

"Go straight to the basement" Santana orders quietly as she swings the car into the driveway and guides it into the garage. Sugar and Brittany share a wide eyed look at the mention of the basement. "Now!" Santana snaps, watching with satisfaction as her girls stumble out of the car, almost tripping over each other in their haste to get out of the garage.
