ROUND TWO: Wow. I was gone from this story for a long time, and for that I apologize. I've made some edits on this story, but by far the biggest of all is the change in title. As most of you know, this story was titled "Okay", representing the response she gives to Mark when he asks her if there was anyway that could make it work. I've changed the title to 'I'll Stand By You' originally by the Pretenders, however I prefer the Glee Cast Season One Cover, sung by Cory Montieth. I think this title fits the story very well, because in the begining of the story, Lexie agrees to stand by Mark through Callie's Pregnancy, and as the story progresses, Mark becomes the one who is standing by Lexie. I recommend reading the story from the beginning, refreshing your memory, because, like I said, I haven't updated in a long time. So, here goes...

. . .

"I saw the heartbeat today. This is my kid. This is a part of me. Please, is there any way we could make this-" he pleaded.

"Okay." She interrupted him.

"Okay?" he asked softly, afraid if he spoke any louder she would disappear.

"Okay." She said bluntly. "Mark I love you, and I know how hard it is to live without you in my life. I'm not an idiot, i'm not putting myself through this again. I'll raise this kid with you."

"Lexie, I can't ask you to do that." he sighed.

"I want to be part of your family and If this is what it takes, so be it."

"Lex…"

"Mark, shut the hell up. We're going to the courthouse. Right now."

"Did you just propose?!"

"Are we really gonna talk about this?"

"Yeah, we are! I just dropped a baby sized bombshell in your lap and you want to marry me? You need to think about this! You can walk out the door right now, I won't be mad."

"What? Do you not want to marry me?"

"I've never wanted anything more, but..."

"No, no buts. I'm not letting you get away again. You are mine, Mark Sloan. No matter what happens, for better or for worse I want you to be my husband. Whenever I think of not being with you, whenever I think of what we went through I want to curl up in a hole and die. If we get married, I will be able to wake up to you every single morning for the rest of my life. That sounds pretty damn good."

"It does, doesn't it?" he smirked.

"Kiss me, Mark Sloan." She whispered, as he took a step forward. "Oh, crap!" She exclaimed as his lips were almost touching hers.

"Regretting it already?" he whispered into her ear, sending a chill down her back.

"We need a witness!"

….

"What the hell took you so long!" exclaimed Lexie as Alex approached her and Mark.

"You woke me up in the middle of the night, made me drive across town to the jewelry store in the dark while it's pouring rain, made me drive back across town to the courthouse in the dark while its pouring rain and I had to do it without waking up Meredith, Derek, Avery or Kepner. So I'm sorry if it took me a while." said Alex.

"What she meant to say was 'Thank you Karev for being the witness at our wedding and keeping it a secret'." said Mark, clapping Alex on the back.

"Why was it that we're keeping it a secret?" he asked, as they hurried into the large white building.

"I didn't want anyone to know, not until it's done. Once were married, they can gossip all they want, but they can do anything about us." She sighed, wiping her tears and holding Mark's hand. "Let's go get married."

"Let's go get married" he said pressing his lips against her temple.

"I cannot believe we just did that!" she giggled, taking a sip of champagne, right from the bottle that Mark had hidden in the back of the fridge.

"Lexie, we have to talk." He sighed, taking the bottle from her and placing it on the counter.

"Can't we talk in the morning?" she asked.

"No, we can talk now and have fun in the morning." He sighed, patting the couch.

"Fine. You can ask all your sad depressing questions" she sighed.

"Are you sure you're okay with this Lexie? With the baby?"

"You. Are. My. Husband. For better or for worse. Sure I wanted to be the only person who could give you kids, but that ship had sailed when Sloane came along. And I'm not absolutely thrilled that you slept with Callie, but she isn't gonna abort this baby, and frankly I don't want her to. We are married now. And she might be the one carrying this child, but I am its mother too. I might have missed the first ultrasound, but I'm going to be there for the second, and the third and all the ones that come after that. And down the road I'm gonna have your children. And we'll all be a big happy family. Okay?"

"I love you so much Lexie Grey." He said, pulling her into his lap and pressing his lips to hers.

"Sloan." She mumbled in between kisses.

"What?" he asked

"Lexie Sloan. Doctor Lexie Sloan. Doctor Alexandra Caroline Sloan." She felt his smile grow across her skin.

"That sounds good."

"Yes it does." She kissed him again, knowing everything at this moment, was perfect.

"Why are you so happy?" asked Meredith, walking up to Lexie at the nurses' station.

"I'm bright and shiny, remember?" she said, covering her two new rings with a chart.

"You, Lexie Grey are hiding something."

"Really, I'm not, but I have to go down to see Patricia, go to H.R."

"I can walk with you to H.R."

"It's fine Meredith, I'm a big girl, I can go myself." She walked away, and fell into step with her husband.

"How'd it go with Meredith?" he asked.

"Not good. What about Derek?"

"Haven't seen him yet. But we have surgery together. See if you can scrub in." he kissed her cheek and they went their separate ways.

….

"So, you and Doctor Grey are back together?" asked Derek, as he Mark, Arizona, Alex, Lexie and Jackson stood around the O.R. table.

"We are." Replied Mark, looking at Lexie. Arizona looked questionably at Mark, but her glance went unnoticed.

"And Are you and Doctor Torres back together?" asked Derek not lifting his eyes off of his patient.

"We are," smiled Arizona. "It took me a while to convince her, but I did it."

"Congratulations, Doctor Robbins." Said Alex. "You too Doctor Sloan."

"Thank you" said Lexie automatically, and everyone's heads turned.

Alex coughed awkwardly and Lexie mentally stabbed herself with a ten-blade. Mark was looking at her like she'd lost her mind and Derek cleared his throat.

"Anyone care to explain?"

"We, uh, got married, Lexie mumbled, suctioning.

"Oh?" asked Derek, looking at her.

"Yeah." said Mark.

"Shotgun wedding?" asked Arizona, "Oh, you're not pregnant too, are you?"

"Who's pregnant?" asked Alex.

"Not me." said Lexie.

"Does she know, Mark?" Arizona demanded, glaring at Mark.

"I know." Lexie responded, "The wedding was my idea. I'm in this with you, Doctor Robbins." she laughed.

"This is gonna be one hell of an adventure."

"Eighteen years," Lexie laughed, forgetting all about everyone else.

"Eighteen years!" Arizona laughed.

"Eighteen years." Mark sighed, causing the two of them to burst into laughter.
