Thanks to everyone for the great reviews!

…..

It had been a little two months since Mark and Lexie had gotten back together. They had been taken things as slow as they could, but Lexie practically lived at Mark's place and was enjoying figuring out her role in Sofia's life. They had had to deal with their fair share of drama from their coworkers, especially since Jackson was Mark's plastics prodigy, but their coworkers had finally been able to warm up to them.

They were standing in the parking lot, wishing the residents good luck as they left for their boards. Mark was giving Jackson some last minute tips and Lexie was looking around for her sister.

Just as the bus was about to leave, Meredith through the doors. "Sorry! Zola was sick!"

"Grey, get your ass on that bus and do what I taught you to do!" Bailey yelled.

"Good luck, Mer!" Lexie called after her sister. Meredith got on the bus and it left.

….

Later that day, Lexie sat down next to Mark in the cafeteria and let out a heavy sigh.

"Busy day?" Callie asked, looking across the table.

"The entire fifth year class are taking their boards and since most of my class got fired, my day has been absolutely insane"

"And you're trying to show off for chief resident," Arizona pointed out.

"It's not like I'm going to get it. Owen's one of your friends and I'm your girlfriend, they'll scream favoritism. You know how bad things got when I was intern and everyone found out. I can't get chief resident only to lose it over our relationship," Lexie explained, shoving a sandwich in her mouth.

"Little Grey, you're easily the best resident in your class, you're practically the same skill level as the fifth years. There's no reason you shouldn't be chief resident.," Derek said with a grin, before getting up from the table. "See you in OR 2 for your solo craniotomy in an hour," he walked off.

"My what?" Lexie began to giggle. This would be the first neurosurgery she performed alone.

"Wanna celebrate?" Mark whispered in her ear. Lexie nodded and they walked off to an on call room.

…

Lexie laid next to Mark in bed in the on call room. "This time tomorrow I could be chief resident," she said, grinning at him.

Mark grinned back. "Why are you acting so surprised? You're the best resident in your class, most people think you're a fifth year.

"Because," Lexie said, sitting up, "I was the girl who fell in love with 007, then her attending AS an intern. I was the girl who arranged a crazy cabal of cutter interns. I was the girl who had to be admitted to psych and threw a softball at your girlfriend's boob. I may be a good doctor, but you have to admit I don't have the best reputation."

"Lex," Mark sat up next to her, "You are Little Grey, Lexipedia. You helped make a woman speak, put a face back on a man. You probably know more about medicine than anyone here. You're a damn good doctor, but you're more than that. You put me back together, you make me and everyone else better. You're on the path to be a badass neuro god, probably even better than Derek. Go, save lives, prove to Hunt that you deserve to be chief resident," Mark said with a grin, kissing her.

Lexie kissed him back and jumped off the bed. She turned before she opened the door. "I love you, I don't know why I couldn't say it sooner," She said with a small smile.

"I know. Now go. Rock your solo surgery," Mark said with a smile.

Lexie grinned and walked out.

….

Several hours, Lexie walked by the bulletin board and saw a white piece of paper; a piece of paper proclaiming the name of the chief resident. She took a deep breath and walked up. She slowly read the piece of paper: "CHIEF RESIDENT: LEXIE GREY." "Congratuations, Dr. Grey. You'll make a fine chief resident," She turned to see Dr. Webber standing behind her.

"Thank you, Chi- Dr. Webber." Lexie said with a smile.

"Now go celebrate, you only have a week or two before Kepner passes down the position and you'll be up to your ears in OR boards and resident schedules."

"With all due respect for, I was born for this job," Lexie responded. Dr. Webber grinned and walked away.

"My girlfriend is not only a badass neurosurgeon, but also badass chief resident," Mark whispered, coming up behind Lexie and wrapping his arms around her.

Lexie turned and kissed him. "I have to check on my patient, but your better go home and get ready because you are in store for some very dirty sex tonight."

Mark kissed her one last time before turning to leave.

…..

About an hour, Lexie walked through the door of Mark's apartment. Though they still weren't officially living together, she practically lived there.

"Derek called," Mark called from the kitchen. "Meredith passed her boards."

"Really? That's great," Lexie responded, taking off her coat. She walked into the kitchen.

Mark had made a delicious looking dinner and actually set the table, even lit candles.

"What's the special occasion?" Lexie asked curiously.

"You," Mark responded with a proud smile, "You rocked your first solo specialty specific surgery and you made chief resident."

Lexie smiled at Mark. It almost hurt how much she loved him.

He walked over to her and kissed her. He pulled away and wrapped his arms around her neck; hers were around his waist, their foreheads pressed together, gasping for air.

"Marry me."
