Series 9 Rumours & Speculation

[pfgirl1980]

I've been watching the last six episodes again and something struck me as been a little strange.. If the Albany file was such a top secret file would Lucas really have been able to access it using Stephen's name and password? There have been other top secret files which have been needed during other plots and Harry has always had to access them due to his rank and level status?
This got me thinking about Harry's,not so worried,look when Ruth told him about Lucas's strange activity,could Harry already have a feeling about what's going on with Lucas and Vaughn. I'm guessing he didn't know that Lucas had gone for the file because Malcolm goes to see him about it or could Malcolm be in on whatever is going on and he was there to tell Harry that it had 'started'. Why else give Malcolm a fake file to protect if it was to be used in the future as insurance,did Harry know that Lucas would one day go calling for it. My thinking is that the file wasn't just put there recently because Lucas hasn't been back long so why would Harry use his name as one of three who Malcolm was to give it to if there was even another two people on that list?
Also,and a little far out,but as it hasn't been mentioned this series could everything what's going on be the return of 'Nightingale'??
Confused because I am..
