* In "Only a Dream", Superman [[OOCIsSeriousBusiness giving up]] might be seen as only a reflection of the intensity of the nightmare, but there's another explanation. When Superman is fighting and needs to call up more determination under normal circumstances, what is he probably thinking about? The people who need him. His nightmare shifts the scenario in two important ways -- one, most of the people (if not all) he would normally be fighting to save are dead, and two, he's not fighting an outside threat. The biggest threat to any survivors at the moment is [[PowerIncontinence himself.]]

* In "Only a Dream," why does Batman use Frère Jacques as his song of choice? The diner jingle that was playing when he first turned on the radio was set to the same tune, so it was probably still [[EarWorm stuck in his head]].

* In "Only a Dream", Superman's nightmare is horrifying enough as it is...and then you realize that Superman isn't just super-powerful; he has SuperSenses. Destiny forced him into experiencing the deaths of at least three people and the destruction of his city in all the intensity that his senses would allow.

* During Season 2 of Unlimited, Luthor continued to speak to Brainiac's consciousness, apparently still existing within his mind. Said consciousness claims it enjoyed the brief time they were merged and wishes to re-merge once reconstructed. However, after he unwittingly resurrected Darkseid, Luthor claimed to no longer be able to hear Brainiac inside his head. Was a part of Brainiac truly speaking to Luthor, or was Lex manipulated into reviving the New God all along?

* In "Epilogue", Warren [=McGinnis=]'s DNA gets overwritten with Bruce Wayne's DNA, which likely caused a divorce between himself and Mary [[ChocolateBaby because of how Terry and Matt looked nothing like them]]. So a happy family got destroyed to make Batman, [[NotSoDifferent which was what Joe Chill did]].

* Superman's WorldOfCardboardSpeech becomes even more awesome when you realize that the very first time he uses his strength back in ''WesternAnimation/SupermanTheAnimatedSeries'', he refers to tearing the door off a van as if it were made of cardboard. Superman has been literally thinking of this comparison as his reality since he first found out he has superpowers.

* A lot could be explained why many of Batman's Rogues Gallery didn't join Grodd's new and larger Secret Society. Discounting Joker, Harley, Clock King, Hugo Strange and Clay Face, the last time these Rogues ever got together was back in [[WesternAnimation/SupermanTheAnimatedSeries "Knight Time"]], where Batman (Superman in disguise) ''somehow'' survived getting crushed under a huge rock, easily beat Bane to a pulp, and JumpScare Mad Hatter with supernatural speed. If Batman was already terrifying as a BadassNormal with ThouShallNotKill, the Rogues might now believe this is what happens to Batman when he [[WorldOfCardboardSpeech cuts]] loose. To those that joined a team outside their city, Clayface was presumed killed after he exploded. Clock King and Strange only joined Task Force X since Cadmus was the government and that they have the resources to protect them from any retaliation by the League but since Cadmus has shut down, what else is there to protect [[OhCrap them now]]. Not only that, Joker broadcast his show of the Justice League fighting the Royal Flush Gang with him revealing it was all part of a scheme to use Ace to MindRape the viewers and later received one soon after. Since Grodd has mind powers similar to what Ace had, the Government fully supporting the Justice League and a Rogue allegedly killed by the League after joining Grodd, they rather take their chances staying in Gotham.

* How about the [[WorldOfCardboardSpeech Superman and Darkseid fight]] in Destroyer? Where Superman casually tossed Darkseid through ''multiple skyscrapers''? Now, in Metropolis, everybody probably heads for the basement when a metahuman fight starts, and [[YouDidTheRightThing the alternative was far, far, far worse]], but ''still''...

* If anybody understands Superman's WorldOfCardboardSpeech then it's the Flash. When he swaps brains with Lex Luthor in ''The Great Brain Robbery'' we get to see all the powers he keeps tucked away and while they're played for laughs in the episode, they're clearly just as lethal as Superman's, if not more. Just thinking of what a gone-dark-side Flash could ''do'' if he wanted to...

*** Every single one of the villains Lex hired is OnlyInItForTheMoney. [[BatmanTheAnimatedSeries Batman's own series]] is littered with examples of people just like Lex Luthor hiring supervillains just like the ones working for Lex Luthor with the same promises of a large payout, only to bag on the hired help at every turn and sour the milk. Lex is raising his bribes to keep them from walking out on him instead of [[AppealToForce threatening them into submission like Batman's villains usually do]], but that's only going to work until the other villains decide his money isn't worth it.

** Given that Hamilton turned on Superman because of the results of Superman TAS' ending, it's likely Cadmus started then as well, it just took evidence that the League could go bad willingly to prompt the government to up their budget and allow them to work more actively to counter the League, with Doomsday being one of the things that they'd already done.

* Doomsday is revealed to be a product of [[CapeKiller Cadmus]], meant to neutralize Superman. An earlier episode had Amanda Waller intimate that the genesis for Cadmus was the Justice League episode featuring the invasion of the Justice Lords (the League had had to tell the government about the Justice Lords in order to secure a pardon for Lex Luthor). However, the first opponent the Justice Lords had to deal with when they came to the League's Earth was Doomsday.

* The [[ImpliedTrope implied]] borderline rape in [[FreakyFridayFlip The Great Brain Robbery]] is terrifying when you think about it. I say borderline because while there wasn't any actual intent on any of the two people involved, think about it: Tala had sex with The Flash thinking he was Lex Luthor... And The Flash did it for fear of having his cover blown up. No actual intent, but a whole mess of consent issues. Let's just hope there are psychiatrists in the Justice League universe for poor Flash's sake (As Tala already died in the last episode)...

* After "Panic in the Sky", it pieced together how did Braniac managed to escape Earth. Since Braniac has been subtly influencing Luthor's actions, it's possible he had Luthor built a rocket or a satellite that secretly contained his codes and memories and shoot it into space. Thus, giving rise to the Braniac in "Twilight".

* When the Watchtower's WaveMotionGun was hacked by Luthor and fired at Cadmus' underground base, the real horror was the shock wave of the blast which caused a massive quake that turned the surrounding city into ruins. It stated that nobody died, but you can bet they'll be trapped under layers of rubble for who knows how long? Even worse is that there were no superheroes coming to dig them out...
* What would have happened if Spy Smasher had not taken the super soldier serum from the Nazis in World War II?

* Why is Batman's dream in "For The Man Who Has Everything" just a loop of his dad beating up Joe Chill while he and his mom watch? [[NowWhat He can't imagine his life after that.]]
