Still, Arrowverse is merging with Birds of Prey over a cameo of Helena Kyle. I don't think that should be enough to warrant a merge if we're not merging Stargirl and the other cameos for similar reasons. A scene of the Birds of Prey world taken by Antimatter in a prologue should not warrant a merge if the Titans wiki and Batman 66 isn't merging.
