The Doctor wasn't entirely focused on the answer, however. Captors with the apparently limitless ability to manipulate the city and everything within it was a little more immediately concerning, but these glitches were likely connected to that, so they were worth knowing about.

The memories sounded interesting, however. "Might be doing something with time... Or simply implanting something false. Still, worth keeping an eye out for, isn't it?"
