"Mr. Schue, I refuse to get on stage with Santana!" Rachel said. Santana rolled her eyes.

"I know you think you hate me right now, but don't make everyone else suffer because you're too stubborn to listen to me!" she yelled. Rachel glared.

"There's nothing to listen to! You cheated and you just need to deal with the fact that you got caught and that we're over." she said.

"For the last time, I didn't cheat on you!" Santana exclaimed. Rachel scoffed.

"So, I just imagined you kissing that girl from Vocal Adrenaline, right?" Santana looked away. "Exactly."

"Rachel, just listen to me-" Santana was cut off by a slap to the face. "Rachel." she whispered. The smaller girl gasped.

"Santana, I-" Santana slapped the diva. "Santana, you just slapped me."

"You slapped me first." Santana hissed. Rachel touched her cheek. "You're right, Rachel. We are over. You obviously don't trust me." she said, walking out of their rehearsal room. She had no idea how things had gone from amazing to terrible in one day.

Actually, she did know...

One day earlier...

"Rachel, calm down. We are in Chicago and you aren't even enjoying the fact that we don't have to go to school. Live a little, baby!" Santana said, grabbing Rachel's hand and pulling her into a tight hug.

"Tana, do I need to remind you why we are in Chicago?" Santana shook her head. "That's what I thought."

"Okay, Rach, I get it, but you don't know when you're going to get to come back to Chicago." Santana pointed out.

"I just don't want a repeat of last year, so all of my focus needs to be on the competition." Rachel said. Santana smiled and hugged her girlfriend.

"I promise I won't kiss you during our performance.' she said. Rachel laughed.

"Good to know." she said. Santana smiled. "I know I've been a little distant the past couple of weeks. I'm sorry."

"Baby, it's okay. I completely understand. I know how important Nationals are to you. It's important to me too." Rachel smiled.

"You're the best thing that has ever happened to me." she whispered. Santana blushed. "I'm so happy that I'll have you forever. No matter what happens, you and I will always be okay."

"You know it, babe." Santana said, kissing her girlfriend. Rachel bit her lip and started giggling as they entered their hotel. "Oh my god. Jesse St. James and Vocal Adrenaline are over there." Santana whispered. Rachel's head shot up and looked in the direction her girlfriend was looking. "If he comes near you, I'll hurt him."

"Don't overreact, Santana." Rachel said. Santana rolled her eyes.

"The guy's a total douchebag, Rach!" she whispered. Rachel glared at her girlfriend. "Look at his hair! It's ten percent hair and ninety percent product." Rachel immediately started giggling and leaned into her girlfriend's body to muffle the sounds. Santana laughed and hid her face in her girlfriend's shoulder to hide her laughter.

"Girls, be polite." Mr. Schue said, glaring at the pair. Santana rolled her eyes, but quickly scowled as Vocal Adrenaline walked over.

"What do you want, St. James?" she asked, pulling Rachel closer.

"We just wanted to wish you guys good luck." Jesse said, smiling at Rachel. Rachel bit her lip and looked away, missing the lead of Vocal Adrenaline smiling at Santana.

...

"You're Santana Lopez, right?" Santana looked up from her pizza and nodded. "I'm Natalie Martinez. I'm the lead of-"

"Vocal Adrenaline. Yea, I know. I saw you checking me out earlier." Santana said. Natalie nodded.

"I think you're hot."

"I can't say I disagree." Santana said. Natlie laughed.

"You're pretty funny too. Do you have a girlfriend?" she asked. Santana nodded. "Oh. Who?"

"Rachel Berry. She's our lead." Santana said. Natalie scowled slightly. "Is that a problem? It shouldn't be, considering I don't know you..."

"No, it's just... Rachel always gets the one I find attractive. She got Jesse... She has you..." Santana raised an eyebrow and looked to her side to see her girlfriend sitting next to her. "Hey Rachel."

"Hello Natalie." Rachel said politely, looking at Santana. "Hi there." Santana smiled.

"Hey you." she said, offering Rachel a bite of her pizza. "You were doing so good in rehearsal." Rachel smiled.

"So were you, Tana." she said, kissing her girlfriend. Santana smiled and rested her forehead on the side of Rachel's head. Natalie cleared her throat.

"Look, Natalie, Rach and I were sort of hoping to spend some time alone during our lunch break." Santana said. Natalie nodded.

"Of course. Later." Santana nodded slowly, turning back to Rachel and smiling before kissing her.

...

"Santana, we have to get ready!" Rachel said. Santana ignored her girlfriend and kept kissing her. "Tana, we have to go to that banquet. It's mandatory!"

"I don't want to stop!" Santana said. They jumped as they heard a loud banging on the bathroom door.

"Will you two stop it? The rest of us have to get ready!" Quinn yelled. Santana rolled her eyes.

"S?"

"Yea, B?" Santana asked.

"I have to go to the bathroom." Rachel smiled.

"We'll be right out, Brittany." she said, pulling Santana out of the bathroom.

"You're no fun." Santana whispered. Rachel smirked.

...

"Santana, you look amazing." Santana bit her lip as she saw Natalie walk up.

"Thanks. You look nice." Santana said, sipping her soda.

"Where's Rachel?" Natalie asked. Santana shrugged.

"She's somewhere around here talking to some big shot from NYADA." she said. Natalie smiled and grabbed Santana's hand.

"Can we talk alone?"

"I don't think that's a good idea." Santana said as she was pulled into an empty hallway. "What do you want to talk about?"

"I was thinking that you and I could maybe go out sometime." Natalie said. Santana raised an eyebrow.

"I'm with Rachel. We're in love." she said. Natalie shrugged.

"I don't mind if you don't." she said. Santana rolled her eyes. "Santana, it's okay."

"No, it's not. I'm gonna-" Santana was cut off by Natalie kissing her.

"Santana?"

Santana pushed the other girl off of her to see her girlfriend watching them.

"Rachel." Rachel immediately turned around and ran off. "Rachel, wait!"

"Go away!" Rachel said. Santana ran after her.

"Baby, stop! I love you!"

"You don't get to say that to me right now!" Rachel said, getting on the elevator.

...

Back to the present...

"Baby, please let me explain." Santana said the moment she saw that Rachel had followed her into the girl's room.

"There's nothing to explain other than the fact that you and I are over, Santana!" Rachel yelled. Santana gasped.

"Rachel, baby-"

"Don't you dare call me that, you lying bitch!" Santana flinched. "I don't want to talk to you. I don't even want to perform with you!"

"You have to, Rachel, because if one of us doesn't perform, then we don't have enough people to compete and then guess what happens your dreams of winning a National championship? They die, Rachel, and I absolutely refuse to have you blaming me for the rest of my life."

"You don't have to worry about that, because I won't be in your life after this competition is over." Santana smirked.

"There's a little problem with that plan, baby girl. I live with you."

"I could kick you out." Rachel threatened. Santana bit her lip.

"Rachel, she's just some chick from Vocal Adrenaline. For all you know, she could be..." Santana trailed off. Rachel raised an eyebrow.

"She could be what?" Santana held up a hand, showing that she was trying to think.

"Oh my god!" she exclaimed.

"What?" Rachel asked.

"We are so stupid! Rachel, the lead of Vocal Adrenaline just doesn't randomly start hitting on their main competition right before Nationals. She knew you and I were together when she kissed me. Baby, you're giving them the exact result they want." Santana said.

"What are you talking about?"

"They want you to get distracted by this and not be on top of your game tomorrow!" Santana said. Rachel closed her eyes.

"Tana, I am so-" Santana covered Rachel's mouth.

"It's okay." she whispered, hugging Rachel tightly. "Just don't slap me again, okay?" Rachel laughed.

"Same to you."

"Deal." Santana said as the door opened and the Glee Club walked in.

"How is it that they're already hugging again?" Quinn asked. Santana rolled her eyes.

"Vocal Adrenaline was trying to turn me and Rachel against each other." she said, kissing Rachel's cheek. "But we're good now."

"Definitely. Now can we please go to that dinner thing? I want to see the looks on their faces when Santana and I walk in together." Rachel said. Santana chuckled.

"That's my girl."

...

"Did you see Natalie's face?" Rachel said, grinning. Santana laughed and kissed Rachel softly.

"I love you so much, Rachel." she whispered.

"I love you too, Santana. I am so sorry for everything."

"I know, Rach. I'm sorry too." Santana said, grabbing Rachel's hand. The diva smiled softly and kissed her girlfriend.

...

"This is officially the best day ever. We made up and we're the National champions!" Rachel squealed. Santana nodded and hugged Rachel.

"I'm so proud of you, Rachel. I'm proud of us." she said, kissing Rachel.

"I can't wait to go to New York with you." Rachel said. Santana grinned and nodded.

"We're going to take over that city, baby."
