Rachel had not seen Quinn since the Lucy incident. Even if the cheerleader was acting confident again at school, working hard on her Prom campaign with Finn, she was ignoring her girlfriend completely. For the brunette, this seemed like a break up and even though she respected Quinn and understood why she could be acting like that, she was hurting. And when she learned that the Glee club was going to sing for Prom she had to chose the song that best described her feelings at the moment: Rolling In The Deep. Adele could write all those songs about break ups and transcript such hard feelings into words, into a melody, and Rachel was addicted.

She was practicing in the auditorium when Jesse St. Jame walked down the stairs and joined her in a duet. Her surprise was there, but she didn't know if it was good or bad. After the song was over, she listened to him talk about his new life and he ended it with:

"-I came back for you." he said, trying to get her back. But Rachel's thoughts were invaded by Quinn, the girl she was in love with.
But after thinking about it, spending time with someone who actually wanted her could only make her feel better. She needed to distract herself from the fact that Quinn was ignoring her and that it hurt a lot.

"-So that's what's going on with Berry!
-What's with her?"

Quinn walked in the choir room to find Mercedes, Santana, Brittany and Kurt talking about Rachel and it caught her attention. She was ignoring her, yes, but it was just until Prom was over. This Lucy thing wasn't helping her confidence and having to hide her relationship to the world was bringing even more pressure to her. And she knew she couldn't come out. She just couldn't.

"-Jesse St. Stupid came back and they're always together.
-Yeah and even if Rachel pisses me off 99% of the time I don't want him to approach her.
-Wait what? Are they like... Together?" asked Quinn.
"-I don't know but even if they aren't yet it is going to happen..."

Rachel and Jesse walked into the choir room together at this exact moment. Quinn turned around to see her girlfriend and before she could even feel bad she left the choir room. She ran in the hallways to find a place to be alone when she heard someone calling her.

"-Quinn!"

When the blonde turned around, Rachel was running after her.

"-What is wrong with you Berry! Are you trying to do this on purpose or what?
-Calm down Quinn...
-No! Fuck you! Fuck us!"

Rachel grabbed the other girl's hand and looked at her straight in the eyes. Both of them were tearing up but they didn't care. Whatever was wrong they had to fix it because they knew that without each other they wouldn't be happy and Quinn would not get better at all.

"-Baby please..."; said Rachel; "I love you, I miss you but you've been ignoring me for almost 3 weeks. What am I supposed to do?
-Am I that easy to forget?
-I'm not with him! I don't want him, I want you.
-Right."

Quinn pushed Rachel away from her and ran out of the school without looking back.

Before they could realize it, the day of the Prom came. Quinn and Finn were acting like a couple and Jesse was chasing Rachel around like a young puppy. And when the brunette sang "Jar Of Heart", she stared at the blonde the whole performance with tears in her eyes. Who do you think you are Quinn Fabray? Breaking Rachel Berry's heart on the day of Prom while dancing with her ex boyfriend? What about these promises? There was no making out in the bathrooms, no "You're beautiful". Prom sucked.

But the brunette had to be strong. While Blaine was singing, Jesse asked her to dance and she said yes. They were getting closer and closer when Finn called Jesse out:

"-Dude, keep it PG!
-Dude, it's not a YB, Your Business.
-It's my school, so it's my business.
-She's not your girlfriend so Beat It MJ!"

And before Quinn could stop them, they started fighting. Sue Sylvester made her way between the two guys and simply kicked them out of Prom.

When Prom King and Queen were announced: Karofsky was elected Prom King and Kurt Hummel was now Prom Queen, Quinn simply stormed out of the auditorium to run into the bathroom, quickly followed by Rachel.

"-Quinn you need to calm down!
-This is YOUR fault! Nobody would have ever voted for me cause they knew that he'd rather be with you.
-That's not true!"

It happened faster than her thoughts: Quinn slapped Rachel as hard as she could. She tried to breathe through her tears and realize what she had just done. The brunette turned around. Quinn said;

"-I'm so sorry. There's no way I'm staying at this school. I need to transfer.
-Quinn...
-I can't! I just can't! Who am I now?
-Mine?"

Rachel walked towards Quinn and put one hand on her cheek while saying:

"-You don't have to be scared. You're the prettiest girl I've ever met and I know I told you that a thousand times before. If I have to say it a thousand times again then I will. You're beautiful.
-But I'm not yours anymore. I'm sorry but I can't."

She went out of the bathroom.

Worst Prom Ever.
