Notable gaps so far, not necessarily complaining, but yowza, not fair to dangle some of these things in front of us:
(Hardly) no Suicide Squad member mentions or appearances is understandable, Cadmus was shown for like a hot second way back in S1 of course but then discarded. Waller is simply not required.
Donna Troy.
How many of Aquaman's supporting cast have we seen now? Both ALs, I never played that videogame with Tula.....Neptune's Beard!
While I totally get it's not a Batman show, we've had blink and miss it references to Killing Joke, Damian, and now the Court.
I also can't not think where Raven and Starfire are but again due to the show's template I understand their absence. They are also simply not required.
Same with Supergirl, most of the characters from the other live action shows, with Black Lightning being the notable exception.
Nice to see the brains trust actually allow the use of a character in the animated series du jour to...... I don't know, HELP RAISE THE PROFILE of a character.
And lastly, if we could please get at least one flashback or time travel episode dealing with this period in the original JL's history when they were all greenhorns/starting up the League, I wouldn't be that mad.
