Quinn and Rachel had been best friends since seventh grade. They bonded with each other in science class, always trying to figure out if their teacher's clothing matched or not. They even had a chart in the back of their notebooks to count the times that he did. And he never did. Over the years, they introduced each other to different TV shows and movies - Rachel of course showed Quinn every musical under the sun. One of their favorite shows, True Blood (even though it is full of gore, Rachel absolutely adored Eric Northman – it was the abs.) was coming back on TV, they decided to have a sleepover and watch previous episodes they had loved. And when Quinn said that she had invited Finn over to watch it with them too, Rachel couldn't help but to be surprised when she felt her heart rate increase.
They made out for the first time that night, Rachel and Finn. Quinn had fallen asleep halfway into a re-run of Friends, and after cuddling for more than half the night, Finn kissed her. And she kissed him back. And she never felt happier in her entire life.
