In Death In The Family, some bread crumbs were dropped to make people think that Jason was Lady Shiva's son . Of course, we're shown otherwise.
Skip ahead a few years, Jason is dead, and in a Bat related book, the writer ignores continuity and says that Shiva was, in fact, Jason's mom, thus making him and Cass brother and sister. Does anyone know which book and what issue this took place in? I remember seeing the scans on scans daily eons ago, but I can't seem to find the thread there anymore.
