In answering vojta'svojta's question, I've stumbled across another:
What happened to the other two AGRA drives in The Six Thatchers?
It was explained that the other two agents were captured or killed, but was it revealed what happened to their AGRA drives?: which we know they carried on them at all times.
They can't be too thoroughly hidden, not only due to their size, but as implied by AJ's frantic concealment of his within a bust: He knew it would be found.
If the drives were uncovered and read by enemy agents, their identities would be compromised... the reason this information wasn't leaked or used against the government can easily be brushed aside by the realization that the Georgian terrorists are working with Norbury. But Ajay doesn't know that at this point?
If he has been locked up for 6 years and believes his captors to have access to the compromised AGRA files for this time, doesn't that make them basically useless to him? If, from his perspective, Mary is the traitor and was working with the terrorists, wouldn't they have tipped her off that he had escaped?
So many plotholes. So many questions.
