One-Shot of Brittany not graduating.
Terrifying thing is, this could actually happen by the end of this season :(
Here's my take on what would happen.

Brittany walked with as much grace as she could when she heard of the dreadful news.

She is not graduating.

How could this happen? She skipped classes just as her teachers told her to so it would improve her grades, but the numerous F's tell another story.

She felt light headed as she gazed down the hallway, looking desperately for Santana. She slid down the lockers, giving up on looking for her saviour. She felt blackness descend , and a heavy weight pushing into her mind.

A voice. A soft, familiar voice broke her from her spell. She was lying in Miss Pilsberrys office, lying on the pristine couch. A dark haired girl occupied the chair next to her, gazing out the window.

'Santana?' A timid voice was heard echo in the room and Santana sprung around to face Brittany, grabbing for her hand.

Not a word was said, only quite comfort in the hand hold and soft breathing.

They remained like that for 20 minutes while Miss Pilsberry talked to the nurse, walking in to inform the girl that Brittany should go home in case she passes out again.

The girls looked at each other, gauging each other reactions. A quite agreement was made and they slowly made their way out of the office.

'I'm not graduating.' Brittany said quietly when she sat in Santana's car. A gasp was heard from the girl next to her. Santana turned to her. 'But you're ever so smart Brittany, your genius. You have your own podcast show, your senior class president. That's bull.'

She sadly sighed and quietly starting sobbing, heads in hands now. Santana couldn't help but feel her heart sinking when she heard the love of her life breakdown next to her.

She reached over and took her hands away from her head.

'Hey.'

Brittany looked up, puffy red eyes, lips trembling.

Santana did everything she could not to cry.

'This is not going to break us up, I promise.' She says whispering.

She looked at her fully.

'I'm going to stay in Lima next year, because you mean everything to me Brit, and I can't bear to be away from you for a year.'

A smile graced Brittany's face, and Santana broke out into one of her own.

'Thankyou San. I love you so much.'

'I love you too.'

Brittany leaned across and kissed her girlfriend with so much passion, it sparked Santana to the core.

'Well, no time to waste B, let's get to my place and hit the books.'

Brittany nodded.

'Yeah, but not before I show you my full appreciation.' Brittany says in a sultry voice.

Santana could not drive home fast enough.
