A/N - I'm sorry it's been so long since I've updated. I've been really busy recently but the updates should start to come a little faster. And yes, I finally brought the Mark and Lexie scenes back! Yay! I always like drama so get ready for a lot!

"Unbelievable, you are UNBELIEVABLE." Lexie dropped her stuff when she walked into the bedroom only to find Jackson, her boyfriend, and none other than April Kepner in bed together. Lexie stormed out of the room and started packing up her stuff from the bathroom. Jackson jumped out of bed and put some pants on.

"Lex, wait! Wait!" He rushed out of the bedroom to go talk to her. "Calm down!"

Lexie stopped packing. "Calm down? You want me to calm down!? Jackson, I will not calm down." Lexie continued to grab her stuff and then moved on to the kitchen.

"Yes," Jackson said, following her. "We need to talk about this."

"What is there to talk about? You know what cheating has done to me in the past, that's why we're together! But here it is, again, and I'm not going to try to deal with it this time. I'm done, we're done."

"Lex, I know. I know. If the circumstances were different, I never would have cheated."

"What the hell is that supposed to mean?" Lexie stopped packing and turned towards Jackson.

"You love him. Not me."

"Do not bring this up again." Lexie scoffed and walked to the bedroom. April had gotten dressed and came out to the living room.

"Lexie, I'm so sor-"

"Save it," Lexie said harshly, cutting April off. Lexie continued into the bedroom and started grabbing all her clothes from the closet.

"It's true! Everyone knows it!" Jackson said, following her into the bedroom.

"Okay fine! I love him! I'll probably always love him! But I didn't want to love him, I wanted to be happy, and you made me happy." Lexie voice started to waver as her eyes became glossy.

"Lexie, I'm sorry." Jackson put a hand on her shoulder as she calmed down.

"It's okay. We wouldn't have worked anyways." Lexie turned towards him.

"So, you're okay?" He asked.

"Yeah. Help me pack?" She hugged him, wiped away a single tear, and then moved on to the drawers.

Lexie and Jackson continued to pack for a few minutes. April decided to make a salad so she'd seem less awkward. Lexie walked back into the kitchen with two bags in her hands.

"Sorry."

"No! Lexie, you don't need to be sorry. I should be sorry. I mean I slept with Jackson and you guys were still together and I know how you feel about cheating because of Dr. Sloan and I-I'm sorry." April rushed to get all of that out.

"It's okay, April. Jackson and I weren't working. This is for the best. I hope you guys work out." Lexie took a deep breath and opened the door. "Bye."

"Come here." Jackson hugged her again. "Go work things out with Sloan. He still loves you."

Lexie nodded and waved as she walked out the door.

"Hey!" Sadie yelled when she saw Lexie in the hospital lobby. "How's my favorite best friend?"

"I'm good." Lexie laughed at her best friend.

"And how's my favorite best friend's perfect guy?" Sadie draped her arm over Lexie's shoulder and walked with her.

"Oh um, we broke up."

"Oh no! What happened?"

"Nothing, it just wasn't working. No hard feelings." Lexie put up her best smile.

"Well I'm sorry, but I'm happy about this. I always liked Sloan better." Sadie giggled as they walked.

"Avery, I need you to clamp this for me," Mark said, gesturing to the artery.

"Um, so this is kind of weird for us to talk about, but I know you still like Lexie, and she likes you too, so, just be good to her this time, okay?"

"What?" Mark asked, looking up from the surgery.

"Oh, I thought she'd have told you by now."

"Told me what?" Mark asked.

"Her and I, we broke up."

Mark and Jackson remained silent for the rest of the surgery. They both scrubbed out next to each other and Mark stormed out without acknowledging that Jackson was even there.

Mark found Derek sitting on a couch in the attending's lounge.

"They broke up," Mark said abruptly, sitting down next to Derek.

"What?"

"Little Grey," he paused "and Avery."

"Really? Why?" Derek asked.

"I don't know, I didn't ask him."

"Avery told you?" Derek asked, confused.

"Yeah, he just brought it up in the middle of surgery." Mark ran his hand through his hair and let out a sigh.

"Have you talked to Lexie?"

"No."

"Do you want to talk to Lexie?"

"I don't know." Mark got up. "She sure as hell doesn't seem to want to talk to me. I'm going to go find Callie." Mark left the room.

"Hey!" Lexie said enthusiastically as she walked into Meredith's house with her two bags.

"You're back?" Alex asked.

"Yeah, I'm back."

"What happened with Mr. Perfect?" Alex asked, stuffing his mouth with popcorn.

"Nothing, we just didn't work out," Lexie said in a reassuring tone.

"What?" Meredith asked as she walked into the room.

"She's back," Alex grumbled with his mouth full.

"What happened?" Meredith asked, concerned for her sister.

"Jackson and I weren't working so we called it quits," Lexie explained as they sat down in the kitchen.

"How are you?" Meredith rubbed her arm.

"I'm good. I'm fine." Lexie nodded and smiled. They both turned when they heard the front door open. Derek took off his coat, glared at Alex, then sat down in the kitchen with them.

"Hey, Mark told me," he said to Lexie.

"What?" Lexie asked, confused.

"Apparently, Jackson told Mark you two broke up."

"Why would he tell Mark? He hates Mark."

"I don't know, but Mark knows," Derek said.

"And?" Meredith asked.

"And nothing. He told me and then went to find Callie."

"Nothing huh?" Lexie laughed. "I'm going to go unpack. See you in the morning." Lexie grabbed her bags and walked up the stairs.

"You think she still likes him?" Derek asked.

"Oh yeah. Does he still like her?" Meredith replied.

"Totally."

"Are you okay with that?"

"I don't know, are you?"

"I don't know."

"I have to do something, right?"

"No, Mark. She just got out of a relationship. She needs time."

"He said they broke up because of me."

"No," Callie retorted. "He said she still likes you, and they broke up. The two could be totally unrelated."

"So, what?" He questioned, shrugging. "She still likes me. I have to do something."

"Mark, no. If you don't give her time to heal, you two will barely last a week."

"I don't like you." Mark scowled at Callie.

"Oh please," Callie chucked. "You love me."

Mark glared at her as she continued to smile.

The hospital was awkward for Lexie for a few days. The gossip wasn't spreading quickly and she kept getting asked about her relationship with Jackson. She left out the part about him cheating to keep him from being bombarded with hate and to keep herself from all the unnecessary sympathy. No one knew except her, Jackson, and April. Even though there were no hard feelings, Lexie did her best to avoid Jackson and April in the hallways. If she had the choice, she would avoid Mark too, but seeing him was inevitable because she was on his service for the week.

"Hey." She said, coming up to him in their patient's room.

"Hi," he quickly glanced at Lexie and then turned to their patient. "Mr. Davenport, this is Dr. Lexie Grey, she'll be assisting me on your surgery today."

"Hi, Mr. Da- "

"I don't know you." He cut Lexie off rudely. "I've been here for weeks, I've never met you. You don't know me, you don't know my case. You can't be in the surgery."

"Mr. Davenport, Dr. Grey is a fine surgeon, the best I've ever seen at her level. You're in good hands, I assure you."

"No!"

"Mr. Davenport, Dr. Sloan will do the surgery, all I'll do is watch. It's how us surgeons learn."

"Fine!" He yelled." You better not come near me in the surgery."

"Okay, I won't," Lexie replied.

"Some interns will come in and prep you for surgery. We'll be back in a few hours." Mark walked out and Lexie followed.

"He's feisty," she said.

"He's just being careful." Mark replied abruptly, trying to do what Callie said and give her space.

"Oh, um, ok." Lexie was taken aback by his answer. "What would you like me to do now?" She asked.

"I don't need you until the surgery. You can go find something else to do." Mark pressed the down button to the elevator.

"Oh, really?" She asked, surprised and confused about why this hurt her.

"Actually no," Lexie perked up when he replied. "Go get me a cappuccino."

"Oh, sure." She said. She turned away as the elevator doors closed, separating the two of them. Lexie went to get a cappuccino and got mad on the way back. How could he do this to her? She's not an intern. She's never been mean to him, at least not when he hasn't deserved it. If anything, he should be getting her cappuccinos. She glared as she rounded the corner. She stood there, staring at Mark, not knowing what to do. "Here," she said, placing the cappuccino into a nurse's hand. Lexie walked up to Mark gracefully.

"Ah, Dr. Grey. Do you have my cappuccino?" Mark asked with a smile on his face.

"No, I do not." Lexie stood her ground, not knowing what was coming next.

"Fine," he said, unemotionally as he walked away.

"Wait!" Lexie hurried after him. "You're not going to say anything? You're not going to yell?"

Mark took a deep breath, regretting what he was about to do. Before she could protest, he grabbed both her forearms and pushed her against a wall. Still holding her forearms so they were at a 90-degree angle with the wall, he leaned his head closer and talked in her ear.

"No, I'm not going to say anything. I'm not going to yell. You do things to me. Things no girl has ever done to me before, and its driving me crazy. If I can't be with you, I need to stay away from you." Mark backed his head away to see a speechless Lexie. Her heart was racing and her breath was unsteady. She couldn't think of anything to say. After a few seconds of silence, Mark loosened his grip and started to walk away. He stopped at the sound of Lexie's voice.

"Who says we can't be together?" Lexie moved to the middle of the hallway, standing directly behind Mark. It took him a second to realize what she had just said.

Within a beat, Mark had turned around, grabbed Lexie's face with both hands, and placed an aggressive kiss on her lips. Lexie bit her lower lip as he pulled away. The mood soured when Lexie realized everyone in the hallway was staring at them.

"Um," Lexie started. "We have a surgery."

"Yeah…" Mark cleared his throat and led the way to their OR.

"Last time we started with sex and secrets and hiding. We're going to do it right this time. I really think he's changed." Lexie tried to explain herself to Meredith and Derek. Alex was standing in the corner of Mer's kitchen just laughing.

"Lexie, we don't want to see you get hurt again. He cheated on you, that's a big thing." Derek tried to convince Lexie to rethink her relationship.

"You know he has a track record of these things. He's not good for you, he's not good with relationships."

"So, cheating once because he was afraid makes him a bad man?" Lexie asked, annoyed.

"No, cheating makes him bad." Derek added.

"If cheating makes Mark bad, then what is Jackson?" Lexie widened her eyes instantly, realizing what she just said.

"What?" Both Meredith and Derek ask in unison.

"Oh, um, n-nothing." Lexie tried to avoid the subject.

"That's not your nothing face. What happened?" Meredith demanded an answer.

"Well, Jackson kind of cheated on me, w-with April," Lexie said slowly. "But w-we were already kind of over and he knew I was in love with M-Mark an- "Lexie quickly tried to explain but was cut off by Meredith.

"I will kill him!" She said, half seriously.

Alex let out a chuckle. "This is great."

"Oh, you shut up." Lexie scowled. Alex laughed at her as he left the room. "Meredith," she switched her focus from Alex back to Mer. "Don't. It's ok, really. Jackson, April, and I, we're all still friends. No hard feelings. It was for the best."

"I still don't agree with the Mark thing," Derek chirped in.

"Okay, I don't need your permission. I'm doing this for me. I want to try again and I'm only telling you guys now so Mark and I don't make the same mistakes we made last time." Lexie stood up as she spoke to make herself clear.

After a few moments of silence, Derek decided to speak. "And is Mark okay with this?"

"W-what do you mean?" Lexie asked.

"Have you talked to Mark about going slow?"

"Well, no, but it's implied. I-we both want to be with each other and we'll do whatever it takes."

"Okay," Meredith replied. "Be careful."

"I will." Lexie nodded reassuringly. "I'm going to go talk to him."

Lexie walked out of the kitchen before Derek or Meredith could say anything else.

Lexie went upstairs and decided to do her hair and makeup after taking a nice, long, refreshing shower. It was only seven o'clock and she was off work tomorrow. She put on a black and white lacey bra with matching underwear under her nicest pair of jeans and a low-cut grey top.

With the amount of time Lexie spends at the hospital, she never really gets the chance to dress up and get completely ready. She usually just washes her face and throws her hair up into a ponytail.

Pleased with her look, Lexie decided to get one more opinion before she left.

"Hey, how do I look?" Lexie asked, walking into Alex's room.

"Hot," he said, taking one glance and then turning back to the tv.

"Good enough for me," Lexie mumbled as she walked back to her room. She grabbed her purse and a black leather jacket and left the house.

"Don't hate me," Mark said unsurely.

"What did you do?" Callie asked, closing Mark's apartment door.

"I kissed her." Mark sat down on his couch.

"What? When?" Callie grabbed two beers from his fridge.

"Earlier today in the hospital. I'm surprised you didn't hear about it, everyone was staring."

"Yeah the gossip hasn't been getting around too quickly lately."

"Anyways, I don't know how she feels about it."

Callie sat down next to him, handing him the beer. "Well, what did she say after?"

"Nothing, I mean, we noticed people were staring so we went off to surgery."

"Did you kiss her or did she kiss you?"

"I kissed her but it's because she said, 'who says we can't be together.'"

"Oh, that Little Grey. What do you see in her?" Callie laughed as she took another sip of her beer.

"Cal, I've told you this."

"I know, and I love her to death but you guys still don't make sense to me."

"She's gorgeous, she's funny, she's smart. Don't even get me started on what she can do in the be-"

"Woah woah woah. Do not finish that sentence please."

Mark and Callie shared a laugh on the couch as they drank heir beer. Suddenly there was a knock on the door.

"I'll get it!" Callie said enthusiastically, handing Mark her beer. She walked over to the door and threw it all the way open to find a dressed-up Lexie Grey standing in the hall of their apartment building. "Oh," Callie said, looking disappointed. "I thought you were food."

"We didn't order food." Mark said, getting up off the couch.

"They could have gone to the wrong address or something." Callie tried to explain herself.

"Callie," Mark said calmly, gesturing across the hall to her apartment.

"Fine, I'm going, I'm going." Callie walked out the door and Lexie entered the kitchen. Just as Mark was about to close the door, Callie pushed herself back in. "Forgot this," she said, picking up her beer. "Sorry!" Callie left and shut the door behind her.

Mark chuckled a bit before he got out any words. He was so surprised Lexie was here. She looked amazing and something about her made his mind go blank.

"Um, hi," he said, trying to hide his smile.

"Hey." Lexie replied calmly. A couple moments of silence passed where they just stared at each other before Lexie said anything else. "Um, I-I'm sorry, I shouldn't be here. I had so much to say and I didn't think and I just came over and now I'm here and I can't remember anything."

Lexie had started to walk to the door when Mark spoke. "Wait," he said. "I have stuff to say too." Lexie turned around to face Mark and she took a deep breath. "I love you." He smiled to himself. "Lex, I love you. Without you I'm miserable, all I do is think about you. Recently, with you I've been miserable. It hurts me everyday to see you and know that I don't have you because I screwed up. I'm not going to screw this up again, Lexie."

Right as he finished Lexie ran up to him from across the room. He opened up his arms and caught her in them. Their lips pounded together along with their bodies as they embraced each other in a tight hug.

"I love you too."

A/N - So, what's? going to happen next? Will Lexie keep her promise to Meredith and Derek or will she get caught up in the moment? Please tell me what you think and I PROMISE there will be a lot more Mark and Lexie to come.
