Welp. That Court of Owls backstory in tonight's episode didn't line up.... Perhaps the journal meant the current iteration of the Court?
Let me run it down this way (along with info in the moments afterwords not in the video):
Bruce wrote about his experience as a kid. His first case as Batman was to investigate more into his parents' death. He discovers it was actually Joe Chill, whom they assumed was just a thief prior to discovering the original Court of Owls was somehow behind that.
While looking for more information on the Court, no more traces of the organization existed as far as he knew. Leading him to believe any recent findings or revival of the group was just a "fairy tale". (Or at least, with the information he had couldn't prove
they existed now.)
Not really a reach, just fills a gap of history during his years as Batman. They are working around the whole Matches Malone and OG Court thing I feel like because they don't wanna make it too complicated for new audiences.
