'Is Mum going to be alright?' We walked into the TARDIS and the Doctor went straight to work.

'Im hoping so but I know who he is. You can never tell with him. Always coming up with suprises.' The Doctor replied.

'Who is he then?' Dad asked.

The Doctor sighed. 'His name is the Master and he's the same as me. Except, evil.'

'But, your the last one arn't you?' Dad questioned.

'Well, I am. Well, meant to be anyway. The Master keeps popping up in various places. He's tried to take over the world many times. Earth that is. He did once, literally. Turned every human being into himself. Everytime he dies, he finds a way of coming back. I dont know how he does it.' The Doctor explained.

I looked up at him, saddness in my eyes. 'But, we are going to save her arn't we?'

The Doctor crouched down slightly, eye level with me. 'Of course we are Katie! I wont let him hurt your mum, your dad or you. I wont let him hurt any of you.' A tear had formed in my eye but I didnt let the water works take over. I swollowed in order to hold them back.

'Okay then.' I replied. The Doctor smiled at me and set back to what he was doing.

'Right then, guessing by the colour of the Masters teleportation light feild, he most likley went underground. And they didnt travel in time so that makes life a lot easier. Ready?'

Dad and I both smiled slightly and nodded. The TARDIS came to life and shook in motion. I grabbed the console to steady myself. My only hope was that Mum was okay.
