If you are inclined to believe that CommanderX is a criminal mastermind, then the conversation could certainly be interpreted that way. Personally I struggle with the idea that a criminal mastermind would simply reveal himself to anybody who asked him about it.
My own interpretation of that conversation is that CommanderX said what he thought Aaron wanted to hear, and implied things that flattered his own ego.
Which speaks not at all to the actual level of involvement CommanderX may have had in the events that transpired, or his knowledge of them.
