I've noticed as well that people seem very vague on there ever having been a Justice Society. I've got three theories:
There are doubtless other possibilities I haven't thought of. Hoping the show will clarify.
The latest episode, "Shining Knight," had a couple of problems, IMO.
When Courtney's real father shows up, he and Courtney have identical pendants. Courtney's is in plain sight (and huge) and she says she never takes it off. I've never seen it before. Has anybody else?
The other problem is that we don't get to see the Shining Knight except in his janitor togs.
Next week is the penultimate episode of the season, which is apparently a two-parter ending the following week.
