I do not own Doctor who.

As the doctor entered the Tardis, he knew that it would not be long before he had to do the hardest thing he had ever had to do. He did not know exactly when he started feeling this way towards her, but he knew as soon as he set eyes on Rose again that his feelings for her where no longer there. Of course he loved her, but not in the way that he use to. He did not experience that rush of goy and excitement he has, when he and Donna are laughing together or are being chased by aliens, for that matter. To him he felt torn, torn between loving the one he used to have feelings for or loving the one that makes him feel so alive, so hot, so breathless. Never before had he experience anything like this before, it was like each one of his hearts wanted somebody different. But as he stood there on Bad Wolf Bay and saw the other Doctor tell Rose that he loved her, he knew exactly where his hearts belong and yet he knew that nothing could ever happen for she just wanted to be friends and nothing more. She had made that point straight away.

'But the last time, with Martha, like I said, it got complicated.

And it was my entire fault. I mean...

I just want a mate.'

'You just want TO MATE??!'

'I just want A mate!'

'You're not mating with me, sunshine!'

'Amate, I want, a! Mate!'

'Just as well! I'm not having any of that nonsense; you're a skinny streak of nothing. Alien nothing.'

'There we are, then. Okay!'

'I can come?'

'Yeah. Course you can, yeah.....I'd love it.'

The thought made him worse; just remembering how excited she was about coming with him, makes it harder for him to make her forget.

As he stood watching her pushing buttons and pulling levers on the control panel of the Tardis, he knew that was happening to her, and it hurt so much to think that he had finally realise the feelings he had for her only to loose her, just like he had Rose without even telling her how he felt. But he couldn't, he couldn't bare to tell her the truth and then having to let her go. It was easier this way, less heart brake.

'I thought, we could try the planet Felspoon!

Just cos... What a good name! Felspoon!

Apparently, it's got mountains that sway in the breeze, mountains that move, can you imagine?'

'And how do you know that?'

Because it's in your head! And if it's in you head, it's in mine

'And how does that feel'

'Brilliant! Fantastic! Molto Beno! Great big universe, packed into my brain! Do you know you could fix that chameleon circuit if you just tried hotbinding the fragment links and superseding the binary, binary, binary , binary, binary, binary, binary, binary-I'm fine'

He knows that she was not fine; he could see the pain and the hurt in her eyes. She is finally realising what is happening to her but she does not want let go, not yet.

'Naaah, never mine Felsmoon, d'you know who I'd like to meet? Charlie Chaplin! I bet he's great, Charlie Chaplin, shall we do that? Go and see Charlie Chaplin? Shell we? Charlie Chaplin? Charlie Chester? Charlie Brown, no, he's not real, he's fiction, friction, fixing, mixing, Rickston, Brixton-

'Ow-!'

'Oh my god'

It was happening, her mind was over loadings, and he could barley look at her. All he wanted was for her to be OK, that it would suddenly stop and she would be all right. But he knew that was not possible. A human would never be able to cope with a time-lords mine, there was just too much for them, to much knowledge, to much power.

'D'you knows what's happening?

'Yeah'

'There's never mean a human-time lord metacrisis before now. And you know why'

'Because there can't be'

He watched her was she continued to fiddle with the controls of the Tardis, trying, hoping that it would go away, that everything would be ok.

'I want to stay'

That hurt. Those four simple words. That is all he wanted in the world to travel with Donna, to have a life with the brilliant Donna Noble. The women who had captured his heart, when he thought that nobody else could. But he had to be strong; he had to be strong for her. To make her understand that there was no other way. That if there was, then he would go to the end of time to do it, just for her.

'Look at me Donna, look at me'

'I was going to be with you forever,

'I know'

'The rest of my life, travelling in the Tardis ... the DoctorDonna

She suddenly realised what I had to do, to save her, I had to make her forget.

'No, I can't go back. Don't make me go back, Doctor please, Please don't make me go back'

'Donna, ow Donna Noble I am so sorry. If there was any other way I would do it. But there isn't. You can't survive with a Time-lord mine. Donna. I am so sorry but it's the only thing I can do to keep you alive' A single tear rolled down the Doctor's cheek, but that was all he would realise. He had to be strong for her, to allow her to believe that everything will be alright.

She saw the tear roll down the Doctors cheek, and she knew how much this must be hurting him. He had lost Rose, found her and then lost her again. He has lost and seen so much pain in his life that she knew that she would allow him to do it. To at least allow him to have the knowledge that he had done something to save her life, rather then letting him see her die. But she had to ask him something, if she didn't, she would always regret herself for not asking him, whether he felt what she felt for him. It wasn't friendship it was something more, something that she never thought she will feel for that skinny little alien dumbo. It was love.

'Ok' Donna looked at him

'But I need to ask you something first, before I forget you. I...I need to know something and I need to tell you something something something, Ow!'

'Donna'

'I am fine'

'You haven't got much time left'

'I know, it's just...I need to know...... I need to know whether you.......whether you love me'

The Doctor was speech list. He didn't know what to say; to admit his feeling for her now wouldn't be right

'It's just that I need to, need to know how you feel about me because.... because...........I love you Doctor'

Those three words were all it took for the Doctor to start speaking again. These were the words that he had always hoped to hear from her and he had thought that he would never hear them.

'I love you' the Doctor whispered to her as he brought his hands around her neck and started to kiss her lightly on the lips. This is what he had always wanted, him and Donna, together.

As the Doctor and Donna continued to kiss a warm feeling began to rise in both of them. However it was not the feelings they where experiencing from their kiss. It was something more, like a link between them. The heat began to flow through both of them. A golden light encircling them, glowing from their bodies. The Doctor saw this light and pondered what it could be but he would not break the kiss. Some how he knew that the link between him and Donna was important and that it should not be broken yet.

He looked in to Donna's eyes, seeing the love she had for him but also of pain and fright. He tried to comfort her as much as he could, bringing her in close to him.

The golden light begins to fade around them, and the heat starts to decrease. When the golden light has finally disappeared, did the Doctor think it was safe to break their contact.

'Donna, are you ok' The Doctor looked worryingly at Donna. Hoping that the metacrisis wasn't causing her pain.

'I ....I don't know, I don't feel right' she said shakily, holding on to the Doctor tighter

'What do you mean?' The Doctor asks, looking Donna up and down, trying to see what was wrong.

'I don't know. I can feel the time-lord mind still, but it doesn't hurt. It feels like it should be there, like it has always been there. But there is something else, like I've change. I don't feel like myself. Does that make sense?'

'I think so, but how could that happen. A human mind could never hold a time-lords, its not possible. Something must have happened when we kissed, some kind of connection. Ahhh think think' The Doctor began ruffling his hands through his hair, hitting himself in the head, trying to figure out what had justed occurred.

While the Doctor was banging his head trying to think. Donna had already figured out what had happened, and it shocked her. She couldn't be, could she?

'Doctor'

'Not now Donna, I am trying to think'

'DOCTOR!!!'

'Look Donna......' The Doctor stop short, as he saw the outraged look Donna was given him 'What'

'You're not the only clever person here now remember' Donna taped her head to enforce the point.

'Oh yeah suppose not. Has the clever earth girl thought of something then?'

'Actually yes she has' she gave the Doctor a cheeky little, know it all smile.

'Well go on then'

'It was a metacrisis. Properly a two way metacrisis, although not the same as before'

'You're brilliant' the Doctor cried bring Donna into a great big hug, noticing that she was shaking slightly.

'Well I am part you' this earned her a kiss on the lips

'When we kissed, I must still have had regenerative energy inside me, from the last metacrisis. The connection triggered the regenerative energy, properly because it was from you and that is what triggered the metacrisis. I am not certain, but from how I can now have the time lord mine, without burning up, must mean that it some how changed me, changed some of my genetics to a time-lords. Allowing me to keep the time-lord mined without burning up. I am part time-lord, part human not part human, part time- lord.'

The Doctor looked shocked, the logic seemed right, but it couldn't be possible. He had to know for sure. Slowly he brought his hands to Donna's head. Before he could do anything, she quickly moved her head away.

'What are you doing? Don't you dare' she looked hurt.

'It's ok. I am not going to do anything. I just want to make sure everything's all right. Trust me; I won't do anything without telling you first'

Noticing the look of concern in the Doctor's face, Donna nodded. She knew that she could trust him.

Slowly he moved his hands towards her head, resting them lightly on her forehand, closing her eyes. He felt the connection of their minds, as he slowly made his way through, looking for any sign of damage. He could feel the knowledge of the time- lord, flowing smoothly through every inch of Donna's mind, blending perfectly with her mind. It fit perfectly, just like his. He could feel the aspects of Donna and those that were not Donna, but time-lord, yet it fit, blending perfectly with her human self, making her part time-lord part human. He smiled with relief. It was true, Donna was absolutely fine. He slowly broke the connection with Donna's mind, opening his eyes; he slowly moved this hand away from her face, slowly moving them around her waist. He notice that her eyes where close.

'Donna' he whispered 'Donna'

Slowly she opened her eyes, yawning then swaying and shaking slightly. The Doctor tightens his grip around Donna's waist.

'Come on lets get you to bed, it must have taken a lot out of you ,to have your genetics changed like that '

'No I'm fine. We need to go and check on mum and granddad, they will be worried sick' she commented, as she slowly made her way out of the Doctor's arms. She started walking towards the console but stopped when she suddenly felt a wave of dizziness hit her and she swayed slightly. Before she knew, the Doctor was beside her, holding her, so she would not fall.

'Come on bed. We're go to see them when you have rested. You can't go to them like this; your mum would kill me. Oh god.... she is definitely going to kill me, when she finds out your a time-lord now'

On this last comment, Donna laughed but then too suddenly felt scared. How on earth was she going to tell them she wasn't quite human anymore.
