If anyone asked, River hadn't done anything to end up in a cell - though as far as she could tell you didn't really have to. As such she wasn't exactly keen to wait around and find out what her punishment was, that and really she'd had enough prisons to last her a lifetime. They had checked her for weapons and confiscated her bag, which she would have to retrieve on her way out as it carried her diary and sonic screwdriver but they hadn't let her without some resources. Mainly her wits.
But still.
She was still inspecting the walls for any weakness or chink when the cell door was opened and new arrivals were ushered inside.
"Oh good," she said when the door was closed again, "Company." Disreputable she hoped, and willing to help or things would be more complicated.
