Addison woke up to the feeling of somebody holding her hand. But it wasn't just somebody. It was Derek. Opening her eyes, everything was blurry. Squinting her eyes she began to realise where she was. Turning her head she started coughing. Derek's eyes shot open, so did Meredith's.

'Hey, how you feeling?'

'Like I've been hit with a bus, what happened?'

'You were in the living room at Meredith's and you must of stood up cause you collapsed on the floor,'

'What did they say is wrong?'

'They don't know, their running the usual tests, but they don't know,'

'Have they looked up my medical history?'

'No, why would they?'

'I know what caused it,'

'Addison, what?'

'Derek, promise me something,'

'Addison, what is it?'

'You won't start your superman act,'

'Yeah, fine. What's wrong?'

'I've got a cerebral tumour, glioblastoma multiforme' Derek closed his eyes to stop the tears forming.

'It's too advanced to cure and surgery is not an option. I'm on mannitol and getting radiation but it's too far gone to clear up.'

'How long have you known?'

'Two weeks,' Derek let go of Addison hand and left the room. Meredith moved up and took hold of Addison's hand.

'Why didn't you tell him Addison?'

'And say what "oh hi Derek guess what, I'm dying," yeah that would go down well,'

'You just told him there,'

'And look what happened,'

'Addison, he still loves you, you need help now. Let him help you. Let him do his superman act. You know he want to put those tights on again,' Addison laughed. It was the first time she had laughed in months.

'I'm going to go and see if I can find Derek, I won't be long,'

'Tell him I'm sorry,' Meredith squeezed Addison's hand and left her. The corridors were almost empty. It was different from the usual busyness of the OR and trauma. Meredith was rarely up on level six. Always level four. Looking in all the rooms it was only when she started walking towards the elevator that she realised where he was. Pressing to go down to the third floor she could sense he was down here. It was his safe haven, where he went when a patient died or when things got too much. She had showed him her special place before Addison arrived and he had adopted it as well. Pushing the door open, she looked down to see him sitting on the floor. His body was shaking with sobs. Meredith walked over and knelt in front of him. Nurses and Doctors passed them but nobody dared interrupt them.

'Derek…look at me,' He kept his head down, not wanting her to see that he had been crying.

'Derek, look at me'

'DEREK, look at me,' Derek raised his head and looked into Meredith's eyes. Her eyes were caring and soothing.

'She says she's sorry for not telling you, but you need to understand where she is coming from. You guys only got divorced a few day's ago and yeah you's were together when she found out but maybe she was worried that you would leave her. Listen to what she has to say. Me and Addison might not have gotten on at first but that was because of the circumstances that we met. I understand why she didn't tell you. Derek, you need to be strong for her. She might even let you do the superman act,'

'She's seriously sick Meredith, she should of told me,'

'Yeah she should of told you but I don't think it's hit her yet. Give her chance and come back with me and see her, be there for her,' Derek stood up and straightened his shirt. The ride in the elevator seemed long and drawn out. Derek was dreading seeing Addison, all he could think of was how long that she had left.

Addison was lying counting the tiles on the ceiling.

'Thirty three tile,' Addison looked up to see his face in the door way.

'What the hell are you doing here?'

'I came to see if you were ok?'

'I'm fine, please leave, just go,'

'Now why would you tell the person you love to go away?'

'Mark please, just go,'

'No, I'm staying, just for a few minutes anyway,'

Derek stood at the end of the corridor. Meredith looked at him, his eyes red and swollen from his tears.

'I'll be along in a minute, go and see her,'

'Promise you'll come and see her,'

'Yeah, just give me a minute,' Meredith walked back along to wards Addison's room when she spotted him standing over Addison. Running into the room she pressed the code button.

'What the hell are you doing here? Get away from her!'

'Stay out of this Grey; it has nothing to do with you,'

'Mark get away from her,' Derek came running down the hall and spotted Mark standing and Meredith shouting at him. Walking up behind Meredith he spotted Addison, her face red. Derek pushed Meredith gently to the side and walked over in front of Mark.

'Get away from her,' Derek was grinding his teeth in anger.

'Why do you care?'

'I may not be with her but I still love her so get away from her now,' Mark started laughing.

'You expect me to leave her just because you tell me to?' Derek's temper broke and his hand made a fist and knocked Mark off his feet. As he fell his head hit the side of the bed, knocking him unconscious.

'Shit,' Derek started shaking his hand. He had caught mark on the cheek bone and his hand was throbbing. The code team ran in and stood watching Derek breathing heavily as Meredith sat on the bed next to Addison.

'Is she ok? We got a code blue for this room?'

'Yeah, but get him out of here and down to trauma, call Bailey to deal with him,' Derek sat on the chair next to Addison and looked her in the eyes.

'Thank you,'

'Hey, next time we'll call the brute squad,'

'There won't be a next time,' Addison arched her back and put her hand on her head. Pain was shooting through her head.

'Addison…' Derek stood up and lowered the bed. Meredith flashed the torch in her eyes.

'Her right pupil is blown, we need to get her down to surgery now Derek,' two nurses ran in.

'Book an OR and page the Chief, he'd want to know, and lets get her down there now,' Derek started wheeling the gurney when Addison's heart monitor started beeping.

'Cold Blue…CODE BLUE!' Derek lowered the bars on the bed and started CPR on Addison. He was panicking.

'DEREK, MOVE!'

'Charge 200, CLEAR!' Addison's back arched as the watts shot through her body.

'There's still no heart beat, Charge again, 300, CLEAR,' Meredith shocked Addison but her heart still didn't start.

Charge 360, CLEAR,' Derek looked at the monitor. His face went white.
