Rose hadn't known Donna for long, but the woman didn't rub her the wrong way at all, and she found it a bit comforting to actually have another woman in the TARDIS. She didn't know much about her, about how she wound up traveling with the Doctor (and even he seemed confused about it, meaning she was farther in the future than them both). Rose did know that she couldn't... exactly know too much, even if she wanted. What would a little bit of extra information hurt?

But no, Rose knew better.

She kept quiet for a little bit, still hanging there, a bit lost in some of her thoughts, a bit just... enjoying other company. Donna could understand what Rose was talking about, at least; she knew the other woman wasn't lying.

Suddenly though, Rose grinned. "Hey, Donna," she said as she pushed away from the doorway, "have you seen a lot of the city yet? I... haven't. Ran into a bit of a trouble, going off on my own and all that. Meeting strangers. You know the deal, I bet." She took a step back into the hallway, still grinning. "How about a bit of girl-time in Paixao?"
