Part 2

"It makes sense." Meredith whispered as she turned over in her bed so they were facing each other, their heads sharing the same pillow as he knotted his fingers with hers.

After seeing her mother and Richard in each other's arms she had simply turned and walked away, leaving Derek stood staring in shock but by the time she had arrived back outside Joe's his car had pulled up alongside her.

When he had offered to stay with her she had gladly accepted because tonight she needed him, his arms around her, his body close. She needed comfort the sort she had only ever found in his arms and right now just for a little while she wanted to feel normal.

"How do you mean, how can this make sense?" Derek asked still unable to get his head around what they had witnessed. Sure he knew back during their residency they had been close but he had never imagined they had been anything more than close friends, close friends who were both married.

"I have memories of them; I remember bits of some of the rows between my parents… I was so young though that they've never made sense till now." Shaking her head she sighed.

"I have one vivid memory after my father left just before we moved to Boston… We were at the park; I was on the carousel and they were fighting… she was crying really crying and Richard walked away but she kept trying to pull him back and he just kept saying he couldn't do it…"

"You think it's been going on for all these years???"

"No… I think this is the first time they've seen each other since then."

Derek rubbed his face sighing

"Your mother left your father for Richard but he didn't leave Adele."

"Maybe that's what she was thinking of when she told me love wasn't always enough…" Meredith spoke half to herself, but Derek heard.

"When did she tell you that?"

"Before I left you, before I left New York,"

"Do you believe that too?" He asked worriedly and moving slightly she kissed him softly.

"I don't want too… For us I want it to be enough!" Her eyes searched his as she lifted her hand to lay it against his cheek,

"Me too."

They smiled at each other and then their smiles faded as Derek moved to return her kiss.

"Are you and my mother having an affair?"

Meredith stood facing Richard in his office, Derek had told her to wait not to just barge in but she couldn't leave it and not do anything.

Whatever had happened in the past between them had affected her, changed the outcome of her life and they owed her the truth.

"Meredith…"

Richard got up from his desk avoiding the green gaze as she stared at him with an almost disappointed look.

"Meredith feels."

Remembering Derek's words he saw for himself the real truth of them and felt riddled with guilt for the damage he himself had played a part in reeking on her young life.

"You are the reason my parents marriage ended aren't you? And it wasn't just an affair she really loved you, it wasn't just this cheap thing where she didn't tell you she was married, she left my father for you…"

Meredith stepped back as he moved forward, his hands held out and right then as the brown gaze finally met hers she saw the answer to her questions.

"Seeing you together last night was like at long last having the final piece of a jigsaw! All the memories of you, the countless rows between my parents… It all just makes sense!"

"Meredith me and your mother it's…"

"Absolutely none of your business young lady!"

Entering the office unknown to the pair of them Ellis closed the door behind herself, her voice that of a stranger watching as Meredith placed herself so she was able to see them both.

"I'm not a child anymore, you owe me this I deserve the truth."

"Why, how exactly does this concern you Meredith?"

"It concerns me because what happened between you back then is the reason my father left! You two are the reason I didn't have him to walk me down the aisle… It's because of you both that I have a whole part of life missing and can never get back!" Meredith didn't shout and though her mother remained impassive she watched as Richard visibly flinched at her word his head slowly lowering.

"I know you have always thought you needed him but you didn't, we were better off without him." Ellis said but Meredith shook her head fighting to hold her tears at bay.

"No I needed him Mom, you may not of but I did…"

"You thinking you need people Meredith is what has got you into this sham of a marriage of your own in the first place."

"So once again we're back to Derek… Why can't you just see how good he is for me! For gods sake he's been picking up and dealing with the mess you made for the last ten years!" Meredith's voice finally rose as she defended Derek in the same argument they had been repeating ever since Ellis had found out about them.

"You were only eighteen Meredith. He was twenty eight he should of known better than to take advantage of a mere child!"

"Seriously … You have the nerve to stand there and say that to me, seriously??? I had been looking after myself for years before that or have you conveniently forgotten the fact you were never around and that our house keeper was more of a mother to me because you were certainly not one or even attempted to be one!" Meredith shouted the anger now blazing in her eyes mirroring the hard fire in her mothers.

"So sleeping with one of my interns and then marrying him was what a way to get back at me?"

"No Mom… I love Derek and he loves me, he was the first person to ever get me and not be put off by all the damage!" Meredith tried to convince her mother for what felt like the millionth time but Ellis only laughed a cold mirthless sound.

"Really he loves you??? Ah so that explains why he kept one of his residents bed warm for the two months before he came here… because of just how much he loved you, his wife!"

"Ellis!" Richard shouted in a voice that would have had all his staff running for cover, unable to stand back and simply let her cause the pain that was currently crumpling Meredith's face. "That's enough, now is clearly not the time for this!"

"No Richard as she said she isn't a child anymore so its time for to face the truth about her own husband and to finally realize there are things she cant just runaway from!"

"No, your lying… your just trying to hurt me…" It was almost a whimper and though she wanted to believe her mother was lying she knew she wasn't.

She was telling the truth, she was giving Meredith the answer to why Derek had that look in his eyes… The look she had again seen last night the exact look that had stopped her from making love when her whole body ached for him, cried out for his touch.

"How could… I mean how would you know that???"

"Meredith no matter how much you may resent the fact I am still your mother and as your mother people often feel the annoying need to make me aware of matters concerning you… This was one of those tiresome times!"

Her tears burned but she refused to show weakness in front of her mother as the pain radiated through her she turned back to Richard.

"I need to uh, I really need to go!"

"Wait Meredith!"

Richard moved quickly forward but hurriedly backing away from them both she stumbled out into the hall to run blindly wanting just to be alone and away from the mocking expression on her mothers face.

"Mer?" Derek called out as she ran straight past him and Bailey, pushing her way past people tripping in her haste.

"Grey!" Bailey demanded both her and Derek turning to the direction she had come from only to see Richard and Ellis arguing.

And as coldness seeped through him Derek knew without a shadow of doubt that somehow Ellis had found out and told her about Sarah.

"Shit! Meredith." Pushing his patients chart into a stunned Bailey's hands he started to run after her pushing past people just as she had.

He only reached her as she started to slow down as she approached the nurses station and taking his chance he grabbed hold of her hand spinning her around as he panted for breath, his stomach lurching at the hurt in her eyes.

"Mer baby?"

"No Derek not now… You don't get to do this now! Right now I just need you to go, give me time I need space give me space!"

But he couldn't he was terrified, terrified that with this time she wanted she would build up her barriers again and regain the resolve that had given her the strength to walk away in the first place. He couldn't let her go and as the tears filled his eyes he shook his head.

"I know how you must feel but just give me a chance to explain, please Mer?"

"No! You have no freaking idea how I feel you cant know! I knew there was something, I saw it in your eyes and this is all partly my fault for not facing it I know that but right now all I know is I had to hear it from her when it should have been you Derek…"

"I wanted to tell you I did but I was scared… Scared to run the risk of losing you again, I just didn't want to hurt you anymore than I already had!" He pleaded trying to keep hold of her as she made every effort to escape him.

"But you have … Cant you see that? I just don't want to do this now; I don't even want to look at you! Just leave me alone!" She cried the tears falling as she pushed at his chest "Please Derek just let me go and don't follow… Do this one thing for me!"

"Derek let her go…"

Mark's unmistakable voice rang out in the silence that had settled as he pulled him away leaving Meredith now sobbing to run off in the direction of the intern's locker room. Leaving him to turn and face not only half of the surgical staff but also his two best friends.

"I cant, I need to…"

"No you need to give her room, Mark?" Addison spoke as she moved towards him and Mark nodded squeezing his friends shoulder.

"Addie's right, the last thing she needs is another fight! I'll go!"

Mark hurried off leaving a frowning Addison behind

"It looks like we arrived just in time… You just don't learn do you???"

I lose my way
And it's not too long before you point it out
I cannot cry
Because I know that's weakness in your eyes
I'm forced to fake
A smile, a laugh everyday of my life
My heart can't possibly break
When it wasn't even whole to start with
