When we first watched ESB, we see Yoda, an old, wise, and powerful Jedi Master. He's the only one of his species, that we know pretty much nothing about. He becomes this special character because he?s so old and powerful, but really because he?s the only of his species that we see and know nothing about. Then in TPM, we see Yaddle, who is the same species as Yoda. Does having Yaddle in the PT take away from the "uniqueness" we saw in Yoda when ESB came out?
