Sure, and what did it matter now how many things she'd done? It was in the past, and now all she was... was this. Glorified babysitter. In the end, that's what he wanted her to be, that's what he left her here for. There wasn't anything else left, nothing left of her Doctor but the stupid key she still wore hidden around her neck and his half-human copy.
When he started apologizing, she winced and looked away. He sounded so much like her Doctor, then. She could almost pretend that it was him standing there... with empty plates... and awkwardness enough to make anyone forget that he was a Time Lord once. No, it wasn't so easy after all to pretend that he was her Doctor.
Rose was grateful when he retreated into the kitchen. Alone for the moment - or at least out of sight - she dashed her fingertips under her eyes and swept away the damning moisture, then covered her mouth with her hand and reminded herself not to make a sound.
I can't do this.
She put her other hand over her mouth, then, and let the sentence roll around in her head. She couldn't say it, no matter how much she wanted to.
I can't do this anymore.
Because what happened if she left? What happened to him? He wasn't her Doctor, but she'd seen enough to know that her Doctor was right about one thing: this one really couldn't be trusted on his own. She was stuck with him.
When she heard movement in the kitchen, she pulled her hands away from her mouth and wrapped them instead around her lager, sucking in a breath she hoped would calm her down enough to face him again.
