*[SPOILER ALERT!]*
I'm telling you mate. And, I know you probably won't believe this even though you made the game, Robert was in on it with Archie. Archie was just his puppet. Sally said herself that the mole had to be someone at the top, and someone who doesn't get their hands dirty according to her source. Robert also had access to the top brass such as Roger who worked on Russia in regard to hush hush Moscow stuff. So he clearly had more access than Archie. He was a traitor as well, but it doesn't fit the memo of Archie. (Good game, would be nice to pause it so I could catch up when typing my notes, seemed a tad too easy when you could fit the events together. please make another one) :)
