The Doctor: How did you get in to this, then? Rattling along with the Preachers?
Mrs. Moore: I used to be ordinary. Worked at Cybus Industries nine to five. Till one day I find something I'm not supposed to. A file on the mainframe. All I did was read it. Then suddenly I've got men with guns knocking in the middle of the night. A life on the run. Then I found the Preachers. They needed a techie so I just sat down and taught myself everything.
