Sorry the last Chapter was so short hopefully this one is longer!

Meredith woke up to see Derek sitting in the on-call room, watching her sleep. Sitting up she remembered what had happened.

'Is my mom ok?'

'She's in ICU. I've not been up since earlier,'

'What time is it?'

'Just hitting 2:30. You hungry?'

'Yeah but I'm gonna get changed first before I eat,' Meredith took her scrub top off to show a skin tight white top.

'Where's Addison?' Meredith scraped her hair up into a messy ponytail.

'I don't know and I don't care. She is no longer my wife,' Meredith looked at Derek. He was deadly serious. Meredith finished scraping her hair back before going over and sitting next to Derek.

'I'm sorry,'

'What for?'

'Destroying your marriage,'

'Mere, it wasn't you. When Addison slept with Mark our marriage ended. When I had the choice between her and you…I only chose her because she had eleven years of my life and I had to at least try. Today was the final straw. When I left you and chief I screamed at her down the hall and gave her warnings to leave the trailer by tonight,' Meredith put her hand on Derek's face. Turning to face Meredith, they locked eyes. Meredith turned away from Derek.

'I should go and see my mom,'

'Yeah…(cough)…I'll see you up there,' Meredith disappeared to the locker room, realising that she was still madly in love with him, but he had broke her heart and he could do it again.

Derek sat in disbelief. He had just let the woman he loved go again after divorcing his wife. Why couldn't he just rewind the past and choose Meredith, let Addison go back to New York and let him and Meredith be happy. But no he was a bastard to Meredith and he felt as though he had blown every chance he ever had with her. Holding his head in his hands, he felt his pager go off.

'No rest for the wicked,'

'SHEPHERD-ICU-ELLISGREY'

Derek jumped up and ran up to Ellis Grey's room to see her convulsing again. Three nurses were holding her on her side.

'10mg Diazepam,' a small whisper like voice slipped through the sound of her body moving rapidly.

'Mom…' Derek turned round sharply to see Meredith's eyes fill with tears. Ellis Grey's body stopped convulsing but he knew there was a much greater problem. Lifting her CT scan up to the x-ray light, Derek spotted a shadow. A Cerebral tumour was causing the fits. Knowing she would need surgery to remove it, he booked an OR under his name, not trusting anybody else with her case. . Meredith stood and watched as Derek turned her back and intubated her for surgery. She was frozen on the spot, unresponsive to anything that anybody was saying or doing. It was the sound of boots coming along the corridor that brought her back. Meredith looked away from her mother to see Addison walk past her and down to the nurses' station, totally oblivious to Meredith, who had followed her.

'Can you tell me where Dr Shepherd is?'

'Yes he's down in room 3268,'

'Thanks,' Addison turned on her heels to see Meredith standing directly behind her. Addison stumbled backwards to the desk.

'Worried that I'll give you a black eye this time Addison that will destroy your perfect image?' Addison looked around fro somebody but there was nobody.

'Guess what Addison? You know how my mom can't control herself; well she's got a cerebral tumour. And I blame you…Yes Addison You!' Meredith pushed Addison and held her down on the desk.

'If anything happens to my mom and I'm not there because of you, let it be on your HEAD,' Meredith stood up as Addison shouted for help.

'Don't go near her or I swear to God…' Derek came running down the corridor and dragged Meredith away to her mothers' room.

'She needs you Mere, stay here,' Derek went back along to Addison.

'She needs controlling Derek, she just attacked me…'

'What the fuck! Addison, shut up right now, I don't want to here it. You deserve everything that you get,'

'I won't sign the papers until I get a reason why you won't to divorce me?'

'You are unbelievable, get out my life and stay out, go back to New York with Mark, he loves you, I don't,' Addison turned away from Derek and headed towards the elevator, holding back the tears. Derek leant back against the wall and took a deep breath in and went back along to Ellis's room. Meredith was sitting in the red chair next to her mother's bed, holding her hand.

'Mom, its Meredith. It's ok; everything's going to be ok,' Derek stood at the door and watched Meredith.

'What are her chances?'

'There's risks with every surgery, you know that better that most people but I think she has a good chance to come out the surgery and be ok,'

'Sit with me a while, just until her surgery,' Derek walked over and put his arm around Meredith. She leaned back and put her head on his chest. She sat with her mum until half and hour before her surgery when she go wheeled away and Derek left too.

'I promise I will do my best,' squeezing her hand he left her standing outside the doors.

'Please god let her be ok,' Meredith slumped herself down against the wall, knowing she would be there for a long time.
