She actually has to pause and make a mental count. At first, it was easy to keep track, each day, each week one of the few she presumed it would take for Numair or the Badger or her Da or someone to find her. But when no one showed up except for a much-older Aly who knew nothing of Daine's disappearance, the count changed. No one was going to come find her, it was just a matter of how long she would be stuck here until someone else figured out how to get her home.

She hasn't been so eager to keep careful track of those days.

"Eight months, just about," she answers, adding a half-hearted shrug, as if that'll make it less depressing. "I've known the TARDIS for seven of them."
