[spoilers] Harry and Ruth

[Silktie]

Yes, I think Harry was using Sam to find out what was going on, and especially whether Ruth's actions posed a security risk. He was willing to let her go on with it as long as she wasn't taking stuff home, which is against the rules, and which she was actually doing. But I wonder if he also had a personal agenda, perhaps - trying to find out if she was serious about this guy. There was maybe an element of jealousy in his actions.
