OK, yay for the Tentoo/Rose fic I have been meaning to write for ages. The idea really came from the fact that the Doctor hates guns, and the way that Rose comes back in Journey's End with a massive gun. I just thought it might be interesting to see how they react when this issue comes up. Enjoy!

"What, it's not like you'd have to use it! Do you think I ever use my gun, unless I really have to? Don't you think I might have put up a fuss when they first tried to make a carry one? The only way they managed to persuade me was when they made me realise that, without you to save the day with a sonic screwdriver and a piece of string, I might not survive dimension travel long enough to find you again. Unless I carried a weapon. So I did. I didn't think you would approve, but you saw – well he—well, you both saw that massive gun I had when I found you again! It didn't seem like such a problem then!"

"I'm sure you're thinking that maybe he wouldn't react like this, that if he were here then we'd have sorted this out ages ago, well I'll tell you one thing Rose: I've been nearly a dozen different versions of myself, and every single one of them could spot when you are being an idiot."

"Who are you calling an idiot?!"

Rose had never enjoyed arguing with the Doctor – in fact it was something that she tried to avoid, unless she really needed to stand up to him about something. And this was something was definitely going to stand up to him about.

The Doctor had come with her after they had come back to this universe a couple of weeks ago, seen what was happening at Torchwood and agreed to be a sort of consultant, called in whenever Torchwood needed extra help with something they couldn't solve, much like Rose was. However, Torchwood regulations stated that each member, when going on a dangerous mission, must carry some sort of weapon. Rose had known from the moment the Doctor was told this that there would be issues.

That had been 2 weeks ago, and since then Rose and the Doctor had spent the majority of their time wandering around London – holding hands as always – buying the Doctor clothes and shoes and all sorts of other things, going to eat at Rose's parents' house, introducing the Doctor to Rose's little brother (who adored the Doctor and followed him around like a lost puppy) and enjoying the fact that they were back together again. It had taken Rose a few days to get used to this new man, and for her anger at the original Doctor to fade enough for her to see what he had been trying to do. After a long talk with the Doctor, that lasted well into the night, Rose found herself thinking that this was really quite like regeneration: the Doctor had changed a little (though much less than he had done in his last regeneration) but was still just about exactly the same man, and he still loved her. They could live one life together, with none of the worry that one of them would vastly outlive the other (unless the Doctor kept walking out into busy roads, as he tended to do. Rose often found herself having to grab him and drag him back by his shirt in order to stop him stepping out in front of cars.)

So all had been reasonably well. The Doctor had been sleeping on her sofa, and there had not been any more kissing or anything of that sort yet. Rose wanted to take it slowly, to get used to their situation and having the Doctor in her life again before anything more happened. Which had all been fine, why wouldn't it be? That is, until Torchwood had called and asked them to come in on Monday to look at some alien artefacts. It was Friday night, and they had just finished their pizza whilst watching Toy Story 2 (the Doctor had been overjoyed to find that Toy Story existed in this universe and seemed sort of smug when Rose commented that she wished they would make a third Toy Story film, though she could not work out why.)

This was the point at which Rose had brought up Torchwood, just vaguely talking and wondering about what they were going to have to do on Monday, and telling the Doctor little anecdotes about things she had done in between trying to get the Dimension Cannon to work.

"But anyway, I'm tired – I'm sure no-one else stays up to watch Toy Story until midnight," said Rose, stretching and hoping - not for the first time – that the Doctor would just come to her bed, instead of sleeping on the sofa. It wasn't even as if she just wanted sex from him (not that she hadn't been thinking about it – actually, probably not so much thinking about it as "staring at him and longing in silence",) she really just wanted him near her every night, to reassure her that he wasn't going to disappear. Living for a couple of years without him had shown Rose how much she needed him to be there, how much she missed his laughter and his smile and the sparkle in his eyes as he looked at her.

"Just a minute, Rose," he had said, and Rose had turned, half expecting...she didn't know what she had been expecting, but it certainly wasn't the serious, intense look that she saw on his face. "If I come with you to Torchwood, are they going to try and make me carry a gun?"

Rose shrugged, trying to keep as relaxed as possible – maybe the Doctor wouldn't have as much of a problem when he saw how normal it had become for her. "I guess so. Is that going to be a problem?"

Which had brought them to where they were now. The Doctor's comment about Rose "being an idiot," had cut rather deeper than she cared to admit – it reminded her of another time, arguing with a blue eyed, big-eared Doctor and being called a "stupid ape." She hadn't stood for it then and she wasn't going to stand for it from a skinny, arrogant half-human Doctor either.

"You might be ruder than you've ever been in your superior Timelord lifetime but you are not getting away with calling me an idiot! What is it next, stupid ape? Humans are idiots and why do you bother with us? Guess what: you're stuck here with me, forever, so you can ditch the condescending tone because I am just about to snap!"

"What are you gonna do, point a gun at my forehead?"

"God, you think you're so good, don't you?" Rose spat through gritted teeth, barely able to understand the levels of hatred that she was feeling for this man who she knew that she loved more than anything or anyone in the world. "Not wanting to use guns doesn't make you good and it doesn't make you clever, all it does is make innocent people put themselves in your way when you're in danger." Rose could see the Doctor bristling at this assessment, but she pushed on, determined to make him hear this. "Sometimes, a gun is the only thing between you and the death of everyone you know and love, and I would use one to save your life ten thousand times over. If you think that not using guns is so important that you would risk other people's lives over that fact, then I don't give a crap what you say, you can stay here, 'cause I don't need you endangering lives!"

There will be more angst in the next few chapters, but there will also be fluff, romance and possibly smut if I can bring myself to actually write it :P Thanks for reading, review if you want, and my tumblr url is donna-and-her-spaceman if you want to follow me :)
