The Three Ghosts of Batman Wiki article

In class we have been discussing wikipedia. One of our assignments is to take a wikipedia article that we fill needs some editing work done and make some edits on that article. The article I have chosen is the Three Ghosts of Batman. This is an article that discusses a Batman storyline from the Batman comics. I feel like this article needs some minor and some major updates. Some of the things I want to edit is, the fact they are not ghosts of Batman but merely a lost memory from his past. Also this story seems to have been resolved yet Wikipedia still has it has incomplete. I want to finish the story. That is my article.
