Lydia saying to Mike: "a drug dealer? If you think that's all he is then you dont really know Gus Fring", reminded me of a scene from Breaking Bad. I think it was when the chicken bro meet with the Don. Hector shoots the other guy, and then the Don tells Gus something along the lines of "the only reason your still alive is because I know who you really are. But dont push it."
Was it ever revealed in Breaking Bad what both these scenes are hinting at?
