Reviews:

Patsy: So glad to hear it! You'll get to see more of Nina's past. Enjoy!
Spencee98: There will be more flashbacks, don't you worry. ;) We shall see more of Carly and Nina as kids, and learn about their family. And yeah she's a horrible person, but you get to see more of why she is that way once we get further into the story!
Leah Tatyana Nicole: I think you're right
mandyg67: You're the only one who picked up on their missing brother Elliot! But you'll have to wait and see if he shows up ;) And we'll find out if Lucas is the father of Michael and Ariana soon
Guest: I'm sorry you feel that way. I'm not trying to offend you or anything, but it does say this story is a Mark/OC story, not a Lexie/Mark story. You have the right to your opinion but in my defence, I never liked Lexie, especially with Mark. I think, in my opinion, Mark is made for Nina and not Lexie.
TheSilverWolff: Welcome back! You've missed so much drama well you were away haha. Enjoy! PS: More Nerek and Mina ahead. ;)
h: Yes, sadly, in fact Carly has. But hey, we can't fault Carly; we don't know the full story yet. So you vote for McSpicy? So you're siding with George, huh. Lol Alex won't be please ;) Enjoy this chapter, ya hear? :D

Chapter 14: No Good at Saying Sorry (One More Chance)

~x~

Nina's day had started off amazing. After dropping Ethan off at daycare, Mark had met up with her to see his son. Once that was finished, they walked together to the Attending's lounge were they kissed some more. She hadn't been this happy in a long time it seemed.

After the many Mark kisses, Nina had gone into surgery to do a Piggy Back which had gone amazingly.

She now stood in front of the nurses' station, updating her patient's charts. She had told the family the surgery went well and was now informing the nurses how to look after her patient. "Doctor Knight," She looked up and found Mark standing before her, a cocky smirk on his face. She smiled as he leaned down to kiss her lips. "You, me, dinner, tonight," He offered.

"Oh, but what about Ethan?" Nina asked playfully.

"I spoke to Bailey," Mark stated, "She said she'd take Ethan for the night if you took Tuck next week. She said something about her wanting to spend time with her husband?"

"Ooh, deal," Nina giggled. They shared another kiss.

"Nina Marie Josephine Knight!"

The couple pull away, jumping apart after spotting an older woman with curly grey hair, jade green eyes and wrinkled skin. The old woman paused and turned to call over her shoulder, "Joseph! Get over here! I found Nina!" The woman shouted.

A man similar to the woman in age appeared, though he was bald and a white goatee. "What Linda?" He asked, walking over.

The woman, Linda, sighed. "I said I found Nina!"

"Oh," Joseph said turning to face his daughter. Joseph's worn hazel eyes locked onto Nina's eyes. He walked over and wrapped his arms around Nina in a hug. "We came as soon as we heard, I'm so sorry darlin'."

Mark looked utterly confused by this display of affection. After Joseph stepped back, Linda scooped Nina up for a hug. "Err…what do you mean? Why would you come?" Nina asked, confused. Mark looked utterly stunned.

"Why of course we came," Linda replied, "We came as soon as we heard about Lucas wanting a divorce. It's a shame that Charlotte is losing her husband…what will she do with two children and no husband?"

Nina connected why exactly her parents were there. "Um, Nina?" Mark began, causing his girlfriend to look at him. "Who are these people?"

She realized that Mark had no idea who Linda and Joseph were. "Mark, these are my parents Joseph and Linda." She explained before turning to her parents. "Mama, daddy; Carly will be fine. She doesn't need a husband to raise a family. Look at me; I've raised Ethan without his daddy for years."

"Nina Marie, you use your sister's proper name that yer mama gave her," Joseph stated firmly. Nina winced gently and Mark looked utterly terrified. "And Ethan does need his daddy, even if he's a no good cheating bastard."

Mark winced at the name.

"But daddy-"

"No buts, Nina Marie." Joseph stated firmly giving his daughter the snake eye. She crossed her arms over her chest and pouted.

~x~

After Carly finally showed up after at least ten pages, Joseph and Linda brought her inside of the meeting room to talk. Mark and Nina were standing together watching as the parents comforted their youngest. "So why did your dad call you Nina Marie?" Mark asked after a long moment of silence. "And don't they know I'm Ethan's dad?"

"It's my name," Nina said glancing up at Mark. "I just prefer to go by Nina. Daddy likes to use our proper names that he and mama gave us. I was named after his mama. And I never saw the need to tell them who exactly had gotten me pregnant. To them, you were this man who had left me and cheated on me, leaving me pregnant."

Mark nodded looking slightly amused. "So Josephine is your middle name?" He asked, moving from the topic of how their relationship had previously ended on bad terms.

"Yes, it is," Nina blushed. "And don't you repeat it to anyone."

He held up his hands. "I won't tell anyone," He reassured, "We were married and I never knew that your real name was Nina Marie. Why is that?"

"I didn't see the reason for you to know," Nina shrugged. He reached over and took hold of her hand, causing a smile to spread across Nina's face, "So dinner, eh?"

He couldn't stop the smirk that spread across his face. "Yeah, dinner,"

~x~

Carly was pulled into the meeting room by her parents. Linda Knight: the perfect housewife and mother. And her father, Joseph Knight: A true southern, firm and a deeply religious, family man at heart. Being raised in their household, she was expected to marry well, get a good job until she married and then have a family.

So, it wasn't okay with her parents that Lucas was requesting a divorce. You didn't get divorced in their family. Oh but sweet Nina did, Carly scowled in her thoughts. Nina was Linda's and Joseph's miracle baby after the doctors said Linda might not be able to have any more children. Carly had been an accident so thus, wasn't the Knight family's miracle baby. So Nina could do no wrong in their parents' eyes.

"Charlotte, how could this happen? You have two children to think about! Have you told Lucas that? Maybe if you mention the kids, he'll rethink this divorce nonsense." Linda offered, her eyes pleading with her daughter.

Carly sighed, earning a glare from her father. "Mama, Luke has good reason to want a divorce."

"You should use his proper name, Charlotte." Joseph scolded her as he gave her a warning look, "The name his mama gave him."

"Sorry," She huffed and cursed under her breath. "But he does have a good reason."

"Nobody has a good reason to get a divorce!" Linda exclaimed, looking ready to faint at the mere suggestion.

Joseph nodded, agreeing with his wife. Carly looked between her parents. "What about Nina's divorce?" She demanded, wanting to understand why it was okay for her older sister to get a divorce but not her. "Huh? She got a divorce and I don't remember you giving her this much grief!"

Her parents frowned. "That was a different situation. And use her proper name!" Joseph snapped at his youngest. Carly frowned deeply, glaring at her father. "Stop acting like a child. Your sister caught him sleeping with somebody else. And usually I wouldn't agree to such a thing, but it wasn't a onetime thing, Charlotte. Your sister had good reasons not to stay with him."

Of course, defend innocent Nina, Carly thought with a frown. "Well Luke has good reasons not to stay with me! Okay? I cheated on him! I cheated on him with Mark Sloan aka Nina's ex husband! And I got pregnant, so I'm not sure who Michael's real father is!"

Her parents were stunned into silence.

The hymns of the Church service echoed inside of Carly's head. She had no idea why exactly she had to come to Church every Sunday. She sat on the bench, watching as their priest sat calmly in his large king chair as Carly liked to call it. Carly watched as her daddy stood up and walked up towards the alter.

Her daddy bowed and then walked forward, before he began to read from the Bible. Carly sighed to herself and let her eyes wander around. People looked content listening to her daddy, which Carly understood. Her daddy was a very religious man and he was humble. Her eyes landed on Nina, her older sister by two years, sitting beside their older brother Elliot. Elliot was a tall kid, nearing age twelve. He had fluffy blonde hair, similar to their daddy and muddy green eyes that was a total mix of their parents. Elliot was seven years older than Carly.

Her eyes stayed locked on Elliot, who was playing with the edge of his jacket. Until of course, their mama spotted him and gave him a firm look. Elliot merely rolled his eyes and returned to what he was doing. Carly wished she could be like that.

Once Church finished with the bread and wine, supposedly Jesus' body and blood, but Carly wasn't fooled, the Knight family walked home in the summer sun. Carly was bored out of her mind. At age five, Carly knew she was smart. She just wasn't Elliot or Nina smart. She held onto her mama's hand, watching as her daddy brought Elliot into the shed. Her mama put her at the table, giving her a book to read to learn more about Jesus. She was supposed to read it out loud.

Nina was allowed to help her mama begin to make lunch. Carly found it boring and made her angry. Why did she have to read from the Bible? Why couldn't she go play outside?

"Charlotte, don't mumble," Her mama stated firmly causing Carly to glance up from the Bible. Some of the words were too hard and too big for her, but as a Knight, she was expected to at least try. "Knights do not mumble."

"Yes mama," Carly said going back to reading about how God created the Earth.

~x~

After the mini showdown with her parents, Carly went to find Lucas. She needed to sit down and talk to him. He had packed his things and left the small house they had just gotten. He stated that he would be staying at the hotel and that he wouldn't be returning home for awhile.

Their two kids had been confused but assumed their dad had a lot of surgeries. She found Luke in the ER, standing by the main desk and doing paperwork. The interns were handling the few patients moving along, who needed stitches in the pit. Carly figured this was the best time to go talk to him. "Luke?" She asked, catching her husband's attention. Heaven only knew if he would stay her husband.

Luke looked up and sighed when he realized who had come to talk to him. "What do you want Carly?"

"I wanna talk," She sighed. He gave her a hard look. "My parents are in town and you know how they are. They don't want me to get a divorce."

"I can't be with you, every time I look at you…all I can picture is you sleeping with that man." Lucas explained, giving her a hard look. "And I don't want our kids to think that a marriage is supposed to be miserable because it isn't."

Carly was stunned, "We've been married almost fifteen years!"

"And yet you still cheated on me."

She looked away, feeling ashamed. "It was years ago,"

Lucas ran a hand through his hair. "Is that supposed to make me feel better? You broke your wedding vows!" Whispers were surrounding them. Lucas caught one that was shocking. He turned to look dead onto her. "When did you sleep with him?"

"Luke-"

"Tell me."

"Seven years ago,"

"Oh god…" He turned away from her, doing the math inside of his head. "Is…is Michael…"

"I honestly don't know," Carly said feeling ashamed. "It was only a onetime thing! I have never slept with anyone besides you and that man. It was only once, Luke, you've gotta believe me!"

He couldn't look at her anymore. "I want a blood test,"

~x~

Up Next: What a Difference a Day Makes: Lucas' and Carly's marriage is on the line. If Michael turns out to be Mark's, they know their marriage won't survive. Mark tries to get the moment right to have sex with Nina for the first time in many, many years. A wedding takes place.

Hey guys! Thank you all for the lovely reviews :) We're getting close to the end of Season 5… oh what to do! Would you guys like to me to continue with Nina's story through season 6 and possibly onward? If I was to, would you prefer the seasons to stay together in one story or create a new for each season? Or maybe do a few seasons together for one story and so on? I'd love to hear what you guys think!

Also, for when Nina and Mark do get it on, do you guys want me to go into detail (so bump the rating up to M) or skip over it (so leave it at T)? OH! And give me your thoughts on if Michael should be Mark's or Lucas'! ;)

Nerdy~

PS: Please review. The more reviews mean longer chapters and a happier writer, so that means more Mina love *heart*
