With all this crazy going on, Donna was more than a little bit worried - about a lot of things. Getting back to a reality where the world wasn’t about to end, avoiding the ridiculously plentiful psychopaths, the Doctor she knew (well he was close enough to the one she knew, anyway; it didn’t matter if he was from the future, did it? At least he still had the same face, and he remembered her again) being poisoned...
She had actually managed to calm down about the latter, at first - he’d said his friend could get him better, after all, so there was nothing to worry about, right? She trusted him, after all. It hadn’t been until the human-TARDIS (which Donna still thought was really weird, okay?) had been hurt, and the new-Doctor (she was going to need to come up with a better way of telling them apart) had said that whole thing about worrying when people say not to worry.
Of course, it was completely by accident that she found him - as it always was, really. She’d been heading down to the complex kitchen to get some tea - she hadn’t had the chance to go buy anything of her own, yet, what with there being psychopaths and demons and Satan all over the place, and even if she’d had the time, she only had the money the people here had given her when she’d first arrived, and it was nice of them to give it to them but it wasn’t going to last very long; she’d need to see about finding work, soon. So she’d been going to get tea, because it generally helped when she was worrying about things she couldn’t do anything about, and she caught sight of a crumpled-up form laying in the hall.
A familiar crumpled-up form laying in the hall. She rushed to his side, dropping next to him and reaching out to shake him gently, trying to get him to open his eyes, grin, laugh and say he was playing some kind of stupid alien joke on her, the kind that’s only funny on, like, three planets none of them Earth so she could hit him and make him have tea with her and maybe make him eat something, because seriously, he was all bones...
...and if this wasn't a joke, she had absolutely no bloody idea what to do, here. This was way, way beyond her skill area, with the medical things and the he might be dead and she really hoped he was okay.
“Doctor?” Her voice was quieter than it usually was, smaller and sort of wobbly, and if the situation were any different she'd be following it up with bluster and glaring but right now that didn't seem very important. "You'd better not be dead..."
