OTHER NOTES:

remember green and abrahms under scarlett's control, gill? they had hidden files upon the police system at Clacton...and then set a memory aid - either for themselves or their substitutions upon the system....most likely the latter....as green was to tell abrahms....what was the memory aid? you might laugh...when 'about to go to' that station...they were to refer to it as XANADU...."I'm off to xanadu, then" etc etc....

....the 'gotham city' files, apparently - their overall title/reference point 'on the system'...

oh and donna had added a 1 to the end of their password i.e. 'xanadu1'....in case the pair of them had remembered the 'gotham city files'...and then their memory aid...go figure.
