If you ask me, the alliance of the Doctor's enemies have her.
Unless its a double bluff though, which is entirely possible, they are helping the Doctor out. It could be that they are all pretending to help as their way of getting to her too. Perhaps all the races want her for whatever reason and they are all out for themselves, but pretending to help the Doctor as their way of getting to her. I mean, there has to be more too it. Why would they even care if she lives or dies otherwise. Its not like they are old buds
