Q is not forgetting any of the show's continuity while tying everything together and further progressing the plots and character arcs. This is his true genius.
Well no denying that, for certain. And you're far better at remembering the various continuity details than I am, not to mention all of the source material from other DC titles. This promises to be a most enjoyable ride. From my perspective, there's been very little filler (save maybe for the Lana story).
