<<Do we even know if Kai Leng will have dialouge? I know he will be presented as something of a rival and mirror of Shepard, but he seemed more of a man who lets the Illusive Man talk while he did his job silently, letting his actions do the talking. I certainly hope he has some dialouge but who knows<<
