"Wait so who is this girl?" 

Emily sighed, "I don't really know. Jo said she met her on set and kept going on and on about Big Time Rush, so Jo invited her to join us tonight."

Logan nodded, not all too interested anymore. "Camille said she got a karaoke machine," he said. "She's very adamant about everyone participating."

"I'm not participating."

"Yes, you are!" Camille ordered, entering the crib with Carlos and James carrying in her karaoke machine. "I didn't haul this up here so you could be boring all night."

"Yes, you did," Emily sang under her breath, taking a sip of water. 

"And technically we hauled it up here," Carlos exhaled, him and James catching their breaths. 

"Pizza is here!" Kendall cheered, entering with Alexa, both carrying two boxes of large pizzas. "Jo and her friend not here yet?" 

"Nope," Camille shook her head. "Emily, I'm putting you down for a solo and a duet with James."

"I'm not doing karaoke!" Emily yelled from the couch. 

"Then who's going to sing Summer Nights with me?" James whined from across the room. 

"I will!" 

Emily sat up, seeing Jo and a redhead in the doorway. She beamed, blushing under the gazes of everyone. 

"Everyone, this is Marie. Marie, this is Camille, Alexa, Emily, and Big Time Rush," Jo introduced. 

"Hi, Marie!"

"Nice to meet you."

"Come in!"

She went around, shaking hands with a few, smiling at others before going straight to James, batting her eyelashes. 

"You're my favorite member," Marie gushed, shaking James' hand. "I have like 20 posters of you in my room."

"Thanks," James laughed. "Nice to meet you."

At first Emily didn't think much of it. Marie was a fan, first and foremost, but then it started heating up. The occasional compliment or word of flattery turned to playfully touching his shoulder or thigh, or seating much too close on the couch. James just smiled and would do his best to politely distance himself, but she was a fan. Fans did this thing all the time. Granted, they never spent this much time with one fan in one sitting. 

"What do you know about her really?" Emily muttered to Jo, scooping ice cream from the carton in the kitchen. 

Jo drew in a sharp breath, "I see it, too," she assured her. "She's flirting with him."

"So I'm not crazy?"

"No. She may be a fan, but she's also in your space," Jo reminded her, taking her and Kendall's separate ice creams back to the couch. 

Emily glanced back over to the girl who latched onto her boyfriend. She was now excessively giggling at something he said, hand on his knee. "James!" Emily called. He looked up, quite relieved. "Come help."

He nodded, immediately getting up, stepping over Marie to pretend help in the kitchen. Marie scoffed, awkwardly looking to the other friends, "Ever heard of "please?'" She laughed. 

"What was that?" Emily hummed, her friends going silent, realizing Marie was targeting Emily at this point. 

"I just think you could be a little nicer to him," Marie shrugged. 

"Um," Carlos sang under his breath, turning to Kendall who hadn't yet solved how to diffuse the situation. 

"I appreciate your concern," Emily fake smiled, "but my boyfriend and I are just fine."

Marie rolled her eyes towards the group, scoffing again, "I would never treat him like that."

"Do we do something?" Logan muttered to Camille. 

"Good thing you're not his girlfriend," Emily said. 

"Maybe I should be!" Emily officially dropped the polite facade. Marie stood, "He should be with someone who appreciates him! Someone who deserves him."

Emily tore forward, launching at Marie across the room. She flinched. The room gasped. Carlos cheered Emily on. James wrapped his arms around her torso, lifting her off the ground and swinging her behind him. 

"Emily, stop," he told her. Emily pushed back from him. Silence washed between them as the couple as they stared at each other. 

Jo was about to tell Marie to leave when Emily turned and left the crib. 

He just let it all happen. He let Marie say all those things about Emily, about their relationship. He didn't even defend her. Emily thought maybe he believed it too. That's why he didn't say anything. Maybe Emily didn't deserve him. 

If James thought that, her friends thought that. Jo brought Marie there for James. And she lashed out. Embarrassing herself in front of everyone. 

In her apartment, Emily leaned on the kitchen counter, struggling to catch her breath, choking back a sob. 

She heard the door open behind her, "Em?" James called, announcing himself before fully entering the apartment. "Jo tore into Marie after you left. She kicked her out. Everyone wants to know if you're okay."

"Don't do that just because of me," she muttered, not facing him. 

James frowned, "It wasn't just for you. We all wanted her to leave."

"You wanted her to leave?" Emily retorted in a bitter tone. 

James realized. "Are you jealous?"

"Of course, I'm jealous!" Emily cried, pacing in her mind., turning to face him. "You're James Diamond! You could have any girl you want, and when she's throwing herself at you in front of me all I can think is this is when you realize someone better is out there." He didn't know what to say. "It certainly doesn't help that she's saying what I'm thinking and–" her breath hitched. "And you don't disagree with her."

James heart broke. Taking a step closer, "Maybe there is someone better out there," he told her. "But I don't want some girl who idolizes me and has posters of me on their walls. I want you." Tears formed in her eyes, "I know you don't idolize me and thank god you don't. You see all my flaws and you love me in spite of them. You make me a better person, a better someone worthy of loving someone like you."

Emily lightly brushed a fallen tear away, turning so he couldn't see how embarrassed she felt. James grew a soft smile, stepping the rest of the way, wrapping his arms around her. 

"So you don't think she's pretty?" Emily asked, muffled into his chest. 

"Babe, I stopped caring about other girls the moment I saw you." James laughed a little, rubbing her back. "All night she kept going on and on about how great I was and how perfect and practically treated me like royalty. I love that you treat me like a person. I love you."

The girl pulled back only to go back in, her lips meeting his before locking her arms around his neck. 

"I'm sorry," James mumbled into her neck. "I shouldn't have let her say those things to you. Just because she's a fan doesn't mean she gets to act like that."

"I'm more upset you didn't let me beat her face in."

"That was the biggest mistake I've ever made and it'll never happened again, I promise."

Emily finally let go, "Hey," she said, swinging his arm back and forth, "Wanna go sing Summer Nights in karaoke?"

James blinked, gaping at her. He took off running out her door shouting, "You won't regret this!"
