By the time Monday rolled around, Santana had managed to convince herself that she was seeing things. Just to solidify her point, she made sure to push Rachel as far away from her mind as possible. Unfortunately for her, that feeling grew even more stubborn and her head was throbbing as if carpenters were hacking at it with chisels.

"San!" The Latina turned around at the call, watching Brittany bounce up to her and link their pinkies.

"I had so much fun at Quinn's. It was nice to catch up with her. I only wish you were there with us. Then it would be like old times, right Sannie?" Santana forced a smile at the bubbly blonde and nodded her head.

"We had a movie marathon and-" Santana's breath caught in her throat as she felt a pair of eyes on her. Turning, she saw Rachel standing a few feet away at her locker, her usually brown eyes a smoldering black. She shivered and shut her eyes tightly for a second, trying to shove any thoughts about Rachel away and tried to focus on what Brittany was saying.

"...And it was amazing! Well, anyway, I gotta get going. So..bye, San!" Brittany gave her a hug and scrambled off to class, leaving Santana to steady herself and hurry into Spanish, taking a seat in the classroom just as the bell rang.

"Okay, class. Get out your homework." Santana tuned Mr. Schue out and let her gaze involuntarily fall on Rachel.

The tiny brunette was sitting just one row away and Santana could tell that her usual enthusiasm about schoolwork was gone because she was just staring sullenly down at her binder, one hand holding up her cheek. Santana stared at her, trying not to let her thoughts drift back to the day before, and her eyes widened as Rachel's form spontaneously disappeared. She was about to open her mouth and say something- what, she didn't know- when Rachel was suddenly back and it was as if it hadn't happened. Just like the night before.

Santana calmed herself and clenched her jaw tightly, looking around to find everyone else already half-asleep in their chairs and obviously not a witness to what had just happened. She sighed and shifted in her seat, willing the clock to go faster so she could just get out of there and away from Rachel and whatever the fuck was going on with her.

When the bell finally rang, Santana slipped out of the class and practically ran down the hallway, bumping into a confused blonde.

"Santana?" Quinn arched an eyebrow, her eyes trained on the Latina who continued racing down the hall like a madwoman.

Santana tucked into the bathroom and held onto the counter top, staring into the mirror. She searched her face, not entirely sure what she was looking for, and clutched a tangle of dark hair in her hands.

"I'm not crazy. I swear, I'm not crazy." She whispered at her reflection, ignoring the little voice in the back of her head pointing out the evidence against that statement. Not feeling Rachel's arm, seeing her disappear not once, but twice..

Releasing a sigh of frustration, she looked up as footsteps sounded from behind her. Two tanned legs strolled in, then two arms, then-

"Berry," Her eyes strained to catch sight of the eyes hidden beneath the girl's long bangs.

Rachel stopped moving, her face the perfect image of a deer caught in headlights.

Santana stepped closer, her hand reaching out to brush along her arm. "I saw that. In class."

A brown eye peeked out from under the bangs for a second, just long enough for the taller girl to notice its dark hue.

"I see that, too. In fact, Berry, I've been seeing a lot of strange things lately, and they all seem to revolve around you. I'm not sure if I even want to know why or if I should try to forget all this."

Rachel opened her mouth and ran her tongue along cracked lips. "You should," She finally croaked.

Santana pressed a warm palm to her forehead and released an exasperated huff of air as the feeling pounded in her head, growing stronger with each beat. "And why is that?"

The tiny brunette seemed even smaller as she hunched in on herself. Santana took another step closer, her body only a miniscule breadth away from Rachel's.

"You can't just say something like that and not back it up. You're Rachel Berry, for Christ's sake."

Rachel suddenly raised her head, dark eyes boring into Santana's. "Sometimes things are better left alone. You don't know anything about me, Santana. And that's how it's meant to be. So," She waved an arm between the two of them, "whatever these confrontations are supposed to be, they're obviously not working."

And with a tightening of the hoodie draped around her thin body, Rachel walked out of the bathroom and to her next class, leaving Santana to stare after her with a fixed scowl on her face.
