A/N: This is an AU mainly about Slexie, but there's also going to be some Calzona in it. Lexie accepts Marks proposal, AU.

"I'm saying you could have a husband."

Mark walked away, leaving Lexie speechless. After he had walked the short distance to his apartment across the street from the hospital, he opened the door, took of his jacket and entered the kitchen. He wished he could talk to Callie, but she was still at the hospital. Suddenly, he felt stupid; he could have just stayed there as well. He had no reason to come back, except maybe to shower and change.

He just came out of the shower, when someone knocked on the door. He hoped it would be Derek, so they could have a drink or something, but it was probably a neighbour, who forgot his keys. What he didn't expect was to see HER standing in the hallway.

"Yes." Lexie breathed and after she saw his confused look, she added: "Yes, I want to marry you."
"What…" Now it was Marks turn to be speechless, he definitely hadn't expected this.
"If… of course… you really meant what you said earlier. Not that it matters, I would already love to just be your girlfriend again, because I-I…" Mark cut her of, placing a finger on her soft lips.
"Of course I meant it! But what about Karev?"
"I broke up with him." She sighed." I couldn't be Alex' girlfriend, not when I love… you. Because I do, I love you."

Mark smiled, pulled her closer and kissed her. He had just enough time to pull her inside and close the door before Lexie ripped of the towel, draped around his middle.

The next morning, Mark pulled a little black box out of the drawer of his bedside table and he turned towards the beautiful woman who lay, still asleep, besides him.

"Lex, Lex wake up." He whispered softly, while brushing his thumb slowly over her cheek.
"Mark! What's wrong? Are we late for work?"
Mark chuckled and answered: "Nothing's wrong. I just wanted to give you something."
He showed her the box and opened it. He smiled as she gasped when she saw the white-gold ring with the diamond on it surrounded by five smaller sapphires, so it looked like a flower.
"Mark! You shouldn't have! When did you even have time to buy it?"
"I actually bought it a while ago, before we broke up. I guess I just always knew you were the one I wanted to spent the rest of my life with."
He put the ring on her left hand and she kissed him.
Mark was the one who ended the kiss as he said: "Come, I'll make you breakfast." He got up, reached out his hand to help Lexie get up and together they walked towards the kitchen, after Lexie put on one of Mark's T-shirts and Mark put on some boxers.

Mark pulled out a box of cereal and some milk and started to make coffee. Lexie grabbed the box and poured it into two bowls together with the milk. She smiled at the fact that he still had cereal, because she was the reason he started to buy it in the first place. The thought that he still bought it, even though she, with her stupid egg allergy, causing her to not be able to eat much else for breakfast, wasn't around anymore, warmed her heart.

While they were eating breakfast, Lexie started to think of Meredith and Derek and about what they would say if they found out about the engagement. Mark was talking about a surgery he had later on the day.

"Miss Johnson has been waiting for this new nose for ages! Maybe you could scrub in?"
"I'm on Dereks service today, sorry." Lexie smiled again, about how natural being with him felt, but then decided to voice her concerns.
"Mark? What should we tell people at the hospital? What would they think about me breaking up with Alex and being engaged to you on the same day?"
"You're right, that could lead to some problems, especially, with your brother-in-law. Maybe we need to keep it a secret for a while?" He answered, after he had thought about it for a while.
"But I don't want to keep it a secret! I want everyone to know I love you! And hey, they have to come to the wedding one day."
"Yes, of course! But maybe it's best if we let them get used to it? What if next week, we tell them we're back together and a few weeks after that, we can tell them about the wedding?"
Lexie thought this over for a while, before deciding that it was indeed the best way to introduce them to the idea of them getting married and kissed Mark in agreement.

She really had to stop staring at her engagement ring. It was the fifth time she caught herself doing it. She really shouldn't attract so much attention to it.

"Nice ring! Whom did you get it from?" Lexie almost got a heartattack, Meredith had sneaked up from behind her.
"What… Wh-why do you think I got it from someone? May-maybe I bought it myself?"
"Did you?"
Lexie sighed "No."
"Than whom did you get it from?"
"I-I got it from my mom." She really hated lying to her sister, god, she hated lying to anyone, but she couldn't tell her yet.
"Oh! Is that where you were last night? You went back home?"
Getting an idea Lexie answered: "Yes! Yes, I stayed with my dad and I found my moms ring! Um-m would you mind if I stay with him for a while?"
"Sure, is something wrong though? Is he sick?"
"No! No, don't worry! I'm just keeping him company."
"Good. I'm free at seven, I can join you on your way out, so you can come grab your stuff?"
"That sounds great!" Lexie almost sighed in relieve, when she got a page. "I've got to go. Thank you!" She started to walk towards on-call room 5.

"Good news." Lexie lay wrapped in Marks arms in the on-call room. Marks thumb was stroking her face, making the place it touched warm and tingly.
"What is it?"
"I can move in with you again." Answered Lexie, while turning her head so she could look into his eyes and smiled. "Or at least partially. I told Meredith I was with my father last night and I said I was going to live with him for a while"
"Well that's great! Now you can leave your panties and toothbrush at my place again."
Lexie laughed and kissed him lovingly, then she got up.
"Where are you going?"
"To work! We're doctors for gods sake, we better start acting like it."

With her scrubs back on, she walked out of the door.

When she had almost reached the nurses station, she heard Derek call after her.

"Little Grey! I had to switch you to Sloans service today, hope you don't mind."
"Oh no, of course I don't mind!" Lexie's heart jumped a little at the thought of having an excuse to spend the rest of the day with Mark. She tried not to act too happy about it, so she added: "But why? Why can't I stay on your service?"
"Because I don't have any major surgeries right now and for some reason Avery got switched to trauma for the day. Mark really needs a resident for the nose job he's doing."
"Alright then, I'll go find doctor Sloan."

She got into the closest elevator smiling, because she thought she knew why Mark suddenly needed a resident, while Derek could miss her.
