Luke was staring at his sister in the attic which was her bedroom. "Alice, come on. It's mum. We have to go," Luke pleaded.

"She's technically not our mum though. You were grown from synthesised DNA which came from a cryogenically frozen egg. That egg came from Emily. Our real mum. The person who looked after me for thirteen years of my life until she died and I tracked down my twin. The cryogenically frozen egg. You, Luke," Alice moaned from under the duvets. "Sarah Jane has looked after me for six months. That's it. You have no idea how hard it was to find you because she forged your birth documents."

Luke glared at the unmoving shape of his twin sister. Six months ago Alice had arrived on his and Sarah Jane's doorstep with her luggage. She'd explained how Emily had decided twins would be too much trouble too look after so had had one of her eggs frozen. Luke. That egg went missing almost six years ago. When Mrs wormwood had taken it and used it to create Luke. Once Emily died and Alice had found out her twins egg had gone missing she was determined to track it down and it led her to Luke. "Ok, she's my mother. She's the person who made me who I am today. Not the experiment I was. If you don't want to go for mum, then go for me. So that me and Sky can pay respect to the person who's looked after us," Luke told Alice.

Alice popped her head over the duvet. She shook her curly brown hair out her eyes and Luke saw that within the steely grey of her eyes she was crying. She sat up fully revealing a tiny waist and chest. "Alright I will. But it's not my fault if it all goes wrong. Everything I touch is ruined."

She stood up as Sky burst into the room. "Come on you two. We have to hurry the car will be here in a minute," Sky said quietly. Sarah Jane had looked after her and now she'd died leaving eighteen year old Luke in charge of his little sister. Sky appreciated all the work Luke put into looking after her. Alice also helped and she was grateful of that.

Meanwhile two years later

Summer looked around her house. It was completely empty. Her father had taken her brother and ran away. Summer rubbed her neck. She wasn't ill. She could see them. The shadows. All around. Of course once inside the mental institute Summer had claimed she hadn't see them so she couldn't. The phone rang. "hello," Summer said as she picked it up.

"hi Summer. It's Rory," Rory said down the phone.

Summer laughed as she heard Amy shout in the background, "and Amy."

"I knew you were getting out today. How are you?" he asked carefully. Rory was six years older than Summer. They had grown up next door to each other and Rory's mum had been Summer's childminder when she'd been little. They had played all sorts of games together. And when Amy had been around Summer always ended up being the evil being that the Doctor – Rory – would save Amy from. She'd had great fun with them. Two months ago Amy and Rory had visited her in the mental institute and told her the Doctor was real and they'd been travelling in time with him. Summer believed every word no matter how farfetched it sounded. To Summer nothing wasn't possible wasn't ghostly white, clear shadows were mingling in daylight with humans. Summer knew they existed and seeing as Amy and Rory believed her about them she believed them.

"Where are they?" Summer asked, her voice dangerously soft.

"I don't know what you are on about," Rory said. Summer could hear the lie in his voice.

"You know perfectly well what I'm on about!" Summer snapped. "Where has my step-dad taken my brother?"

"Listen Summer. I promise I don't actually know. All I know is that he says he doesn't want you anywhere near them so you can't poison their minds with your illness. He brought a house somewhere and they moved there. I don't know where. He left your house, the house in Kent that you moved to three years ago for you. He knew you had nowhere to stay," Rory explained calmly.

Summer glared out the window. "Well I suppose I will just have to deal with it. Seen the doctor since you visited me?" Summer asked.

"No, not since Christmas," Rory finished.

Summer nodded as she looked at her reflection in the mirror. Her dark brown curly hair and steely blue eyes shone back at her but her pale face looked even worse. Summer heard a strange noise from the garden. "I've got to go," Summer said. She put the phone down and went outside into the garden.

There in her garden was a blue police telephone box. A tall man with dark brown hair stumbled out into the open closely followed by a shorter black haired girl. The man spotted Summer. "Ah! We might be in the wrong place Clara," he said referring to the girl behind him.

"The Doctor," Summer said.
