A/N: Wrote it on Tumblr, decided to post it here.
"Rachel," Quinn said when Rachel let her into the house.
"Quinn, hi."
"Blaine invited us to his party tonight and I'd like to know if you'd be my date."
Rachel smiled at Quinn and said, "I'd love to."
"Great! I'll pick you up at seven," Quinn said and kissed Rachel on the cheek.
"I'll be waiting," Rachel replied and smiled when Quinn left.

Rachel snapped out of her memory. She wanted to claw Sebastian's eyes out. She sighed and sipped her soda. She looked back up and her eyes almost bugged out of her head at what she was looking at.
Sebastian pulled Quinn on his lap. Quinn started laughing and that made her blood boil. She wanted to be the one making Quinn laugh, she wanted to be the one holding Quinn.
"Berry, are you okay? You look like someone insulted Barbra Streisand."
Rachel turned around. "I'm fine, Santana." Rachel turned back around to glare holes in the back of Sebastian's head.
"Ah, you're jealous," Santana said.
"Jealous? Of what?"
"Quinn and the new dude. Oh, don't give me that look."
Rachel shook her head. "Nonsense, Santana. I am not jealous of Quinn and Sebastian."
"Look, I'm gonna go flirt with Brittany, you can stay here and be pissed," Santana said and walked away. She swore she saw Sebastian look at her with a smirk.
Rachel saw Sebastian whisper something in Quinn's ear that made her nod eagerly. Quinn wouldn't cheat on me, right?
Rachel was fed up with it now. Now they're dancing. Rachel marched over to them and cleared her throat. "Excuse me, but can I borrow my girlfriend for a minute?"
Sebastian raised his eyebrow. "By all means, go ahead."
Rachel pulled Quinn into a random room. Probably Blaine's. "Hey, babe. Enjoying the party?"
"Yes. I enjoy watching my girlfriend dance with some guy. Quinn, this is probably pretty stupid of me to ask…"
"Nothing you ask is stupid."
"You wouldn't cheat me me, would you?"
"Except that. Rachel, I only have eyes for you and you only. And besides, Sebastian's gay."
"He is?"
"Yeah, Rachel. And I'm pretty sure that I'm gay, too," Quinn said with a laugh.
Awkward silence.
"So, do you want to dance with me?" Rachel asked.
"I'd love to," Quinn replied and left the room, hand and hand with Rachel.
Sebastian gave Quinn a thumbs up from across the room and she smiled at him. Yeah, Sebastian was a genius.
A/N: Done.
