"So Molly came in to talk to me last night." Meredith said while standing at the nurses station. Mark looked up from a chart and gave her his full attention, which was very hard for him.

"She wants to know about Derek, well more than she already knows." Meredith said absently staring into space. Mark spit out his coffee at the already knows statement. He wanted to talk but he saw the blank look on her face and waited five seconds before she continued.

"She saw in article in Medical Weekly, the same one I was in. You know how I insisted on keeping Shepard in her name? Why didn't you talk me out of it? She was two and we could have made it Grey Sloane like Cassie." Meredith said more to herself then Mark.

"Well it's not like the world is ending, what's different?" Mark said taking another gulp of his coffee.

"She seems curious about our relationship. You know how she is. Curious, quirky, always asking questions. I don't know where all stand right now. Oh yeah, and I think she explained what sex is to Cassie. Not in a bees and birds way." Meredith was rambling now, she knew she was. But she couldn't bring herself to stop rambling. Mark just sighed and put her arm around her.

"Another Saturday morning!" Mandy said bounding into the kitchen. Only her dad was awake, Derek had always been a happy cheerful morning person, Mandy could describe herself like that as well, but only on the weekend. She watched her dad flip banana chocolate chip pancakes, whistling as he held the spatula. "Do a pan flip!" Mandy shouted. She sounded like she was four again. Derek shot her a grin. He flipped the pan up into the air and the three pancakes flew up. One for Derek's head, one for Mandy's, and one in the pan. They both started giggling and laughing.

"You look so funny!" Mandy said shrieking with laughter. Derek pointed at her.

"Take a look in the mirror Miss Mandy." He said. She got up on his feet and they started to dance some kind of waltz around the kitchen. Their pajamas were covered in pancake batter. Mandy smiled up at her dad, he looked carefree and happy. Suddenly they heard a shrill shriek coming from the direction of Addison and Derek's room. Addison stormed into the kitchen holding the photograph. Mandy took the pancake out of the pan and went to eat it at the table.

"Who is this?" Addison hissed pointing at the picture. Derek's eyes widened. He tried to talk but his breath caught in his throat. Meredith's face on Medical weekly stared back at him. But what caught his attention was the picture next to it. A school photo of a young girl sat next to her picture. At first he thought it was a picture of Mandy, but then he saw the dirty blonde curly hair and petite frame. He looked up at Mandy and back at the picture, the facial similarity was there, as were the striking blue eyes.

"Oh, my bad." Mandy said running over as tried to snatch the picture away. Addison held it above her head and shoved it into Derek's face. They both looked down at her.

"What does that mean?" Derek snapped gruffly, his Saturday was already ruined, and his daughter may have had something to do with it.

"Molly's picture and her mom's picture I clipped out of medical weekly. I probably just carelessly dropped that. My bad." Mandy said reaching for the picture again.

"Mandy do you need this for school?" Derek asked receiving a knife sharp glare from Addison. Addison could not believe he wanted to keep a picture of the dirty mistress and the girl who could be Mandy's twin.

"No, why?" Mandy asked tilting her head and taking on an innocent face.

"Do you mind if I hang onto this?" Derek asked her. Mandy nodded for yes and Derek exited the kitchen, heading for the guest room. Addison was about to follow but a thoughtful look crossed her face. She turned towards Mandy with a curious glance. Mandy tried to come up with a quick lie incase Addison had caught on to it not being so accidentally placed in the hallway.

"Mands, what's your pen pal's name?" Addison asked biting her lip hoping for a different response then the one she expected.

"Her name is Molly mom, Molly Grace Grey Shepard Sloane." Mandy said truthfully as Addison nodded and did a fast paced walk towards the guest bedroom.

Seattle, Washington

"So then the lady gets on top of the man, or the man rolls her over it doesn't really matter and-" Cassie blabbered on to the lady at the grocery store checkout. The older women's eyes grew wider and wider and Izzie clasped her hand over Cassie's mouth.

"I am so sorry, you don't know how sorry I am…" Izzie began as Callista began to cry and Ally and Claire we're fighting for the box of Lucky Charms. The lady pointed out towards the door and said she'd give everything to Izzie free if she'd just take the children elsewhere, and never come back.

"Cassandra Elizabeth Grey Sloane! We do not ever, ever talk about things like that! Do you want your father to have to give you a spanking, or your mom to wash you mouth out with soap!?" Izzie asked as they drove home. "I am so talking to Molly when we get back!" Izzie fumed under her breath.

"Molly said that if you threatened that I shouldn't be scared, Daddy's kind of a wimp and I'm his little princess, and Molly said that Auntie Christina is the only one who threatens with soap and actually goes through with it." Cassie said.

"Aunt Stina scary." Callista said holding Maggie, her stuffed dog.

"Yes Callista, Aunt Stina is very scary." Izzie responded.

Later…

Everybody was seated around the dinner table. Christina and Burke had brought Ryan and Taylor over for dinner. Taylor was fourteen and Ryan was six.

"Where's your ring?" Mark asked Meredith, who stared at her right handed ring finger. There was an Emerald ring she always wore, but her engagement ring wasn't there.

"Huh? Oh I took it off before I went to sleep last night. Must've forgotten to put it back on." Meredith said shrugging it off. Mark eyed the emerald ring on her finger.

"I don't remember giving you an emerald ring." Mark asked curiously.

"Oh, um, it was a gift from my mom, you know like Molly's." Meredith said, putting her hand under the table. She'd never taken off the ring Derek had given her. Promising he was going to break it off, then never coming back. She just couldn't do it. Molly glanced at her mom and frowned looking upon her ring. Her mom had given this ring to her, not her grandma. Her grandma never gave gifts, she'd only sent an e-card or two in her life.

"Oh," Christina said loudly, and mentally cursed to herself. Derek's rings, she thought. She wondered how Molly had gotten one. She only remembered Derek giving Meredith one. Meredith shot Christina a panicked glance and then looked down. Did she still have feelings for Derek?

"So when's the wedding?" Callie asked she handed Callista a napkin to wipe her face of spaghetti.

"I still don't know, you never know when the time is right. It will come to me I'm sure." Meredith said. Why hadn't she set a wedding date yet? It seemed to have skipped her mind even after the proposal. Everybody at the table just nodded.

"Is Derek Shepard my dad?" Molly asked bluntly out of nowhere. She had to know. All the adults stopped chewing and turned towards Meredith, pretending to be focusing on something else, in anxious await for her response to Molly.

"Why would you ask that?" Meredith said twirling the spaghetti in her fork. Suddenly she'd lost her appetite.

"Well I want to show you a picture of my pen pal, Mandy, she told me that you guys worked at the same hospital once." Molly said fishing through her pocket. She pulled out a picture of Mandy and handed it across the table to her mom, but Mark got to it first. He slammed his fist on the table, Addison the love of my life, had a baby with Derek.

"What did you say?" Meredith said jumping up from her chair and away from Mark as if he were on fire. Crap, Mark thought, he'd said that out loud.

"Meredith, it's not what it sounded like!" Mark said standing rushing after her.

"Your marrying me! And you see a picture of a girl who looks faintly similar to Addison and the love of your life has a daughter. I'm supposed to be the love of your life, not Addison! We have a daughter, you also have one you adopted. You know what, I think you should go! I'll mail you the ring in the mail!" Meredith shouted, Mark frowned and left her to herself for awhile.

"Daddy!" Cassie screamed following Mark out with tears streaming down her face. Meredith ran after Cassie to see Mark pulling out of the driveway, and possibly out of her life. Her throat choked up.

"Daddy! Daddy! You can't leave me!" A young Meredith cried holding onto her dad's leg.

"Meredith, let your father go, it's his damn life, he can leave if he wants to." Ellis said as she pried Meredith off his leg.

"No! Daddy please don't leave me! Stay! I promise I'll be good! I'll stay out of you and mommy's way!" She screamed prying herself free from her mother's tired grasp. She chased off down the street running alongside her father's car. Her dad rolled down the window. Trying to reason with her, but she couldn't hear him. All she heard was the screech of breaks, and then everything went black.

Meredith grabbed Cassie before she could chase after Mark. Tears streamed down both their faces. Molly began crying at the table and Alex wrapped his arms around her. Izzie told her none of this was her fault. Molly just held the picture of Mandy in her trembling hand, and wept. Christina stood up abruptly. She had to talk to Meredith about the real reason she just chased Mark out, they could've worked through it, something else was behind it.

"Derek what are you doing!" Addison said bursting into the guestroom to find him packing two suitcases. He was throwing some of Mandy's clothes into the smaller suitcase and his into the larger one.

"Molly Grace Grey Shepard Sloane, I'm going to back to Seattle, just to see to some unfinished business." Derek said grunting as he picked up the larger suitcase and swung the smaller one over his back.

"I let it go, I let it go that the love of my life was marrying your dirty mistress! You have to let it go too!" Addison screamed.

"You knew? Did you know about my other daughter? How much do you know about Mark's life then I do? Been in contact lately?" Derek said harshly moving her aside as he exited the room.

"Mom, Dad, What's going on?" Mandy asked and stopped when she saw her dad with suitcases. Her dad walked down the hall towards the front door.

"Mandy, how would you like to visit Molly?" Derek asked and Mandy had a happy look on her face.

"Derek, please you should at least tell her the real reason your going, Mandy, he's taking you to Seattle to make up with Molly's mom, you go and you'll never see me again." Addison said yelling at Derek and speaking softly to Mandy, almost pleading.

"Mandy." Derek said holding out his hand.

"Mandy." Addison said, her face red with tears.

Mandy looked back and forth between the two of them, crying softly to herself. What was she going to do?

AN: Dun Dun Dun! So is Meredith really in love with Mark? Are Derek and Addison over for good? Will Mandy meet Molly? And what can Molly do that will make things worse. I'm not sure how I feel about this chapter, so reviews would be greatly appreciated.
