She’s sure people think he’s whispering obscene things in her ear - and sometimes he does - but today, he’s whispering that he loves her.
She stopped him from saying it the night before. If he said it this time, without her having to ask, it meant that this was real. It wasn’t for fun, it wasn’t another mistake. It would be real.
She didn’t need one more complication in her life, and in her mind, it could only complicate things.
But as “I love you, Quinn” rolled off his tongue, she changed her mind. She pulled back, and instead of running like last time, she looked into his eyes and said it back.
So she grins like a girl in love as he whispers in her ear while the rest of the glee club has no idea what he’s saying.
