I'd first seen Batman Begins in 2005 when it first came out and I was six years old, I hadn't known many Batman villains at the time aside from the more well known ones (ex. the ones usually used in the 1990s animated series, The Batman, and the previous films) so when I saw a bald guy with a knife trying to kill Rachel and the random kid Batman met earlier she was trying to protect, I didn't know or care who he was. But after gaining a wider knowledge of Batman's rouges gallery in recent years through my wider access to more mature Batman stories, I'd begun to know villains like Hush and Zsasz. But more to the point, I began watching Batman Begins a few hours ago and noticed that Zsasz was the guy I mentioned earlier, which was much more noticable because of the fact that he had the tally marks on his neck and his name was uttered earlier. But what I do want to ask is why he never made a cameo appearance in The Dark Knight alongside Scarecrow?
