I'm aware that Ryan knew he was alive, an audio diary from Episode 1 has Suchong explain that Ryan himself offered good salary to him, what I was trying to say, is that both of them may made an agreement, such as letting Suchong's status be known as dead to the public, but keeping him do more and more inventions (as we know he worked with plasmids for Ryan Industries).

And judging from the Audio Diary Pawn of Atlas mentions, it would be safe to say that he did knew Fontaine was still alive. The real question is, then, why would Fontaine want him to reduce ADAM in his plasmids if he's not in charge anymore and that's not his problem? And, why didn't Suchong tell Ryan or someone about this? In 1, he has an audio diary that says that Fontaine is dead, so he surely thought it was real, so, a mysterious audio diary from his dead master would have come as a surprise, wouldn't it?

As for Gil, I'm keeping my own theory, I find it satisfying enough to explain why he thought his partner was dead and he was working on the Alphas unknowingly, as his counterpart was in another part of the city, working with the Protection Bond.

There are a lot fo confusing things, however, Ken might be the only one who has a straight answer, though I doubt he will give it to us.
