When Luthor is seen outside of the Metro Tower for the first time, Evil Star is nowhere to be seen. Switch to the Justice League, then close-up on Lex. Evil Star suddenly appears behind Lex. Where did he come from?
When Weather Wizard and Killer Frost are welding the ship's panels together, they heat and cool the seams together very quickly. Any welder/metal worker knows that if you cool hot metal quickly with liquid or other methods, it becomes brittle and prone to cracking. To prevent this, hot metal needs to air dry.
When Lex jumped over the balcony, you briefly see him wearing his armored gloves, but then they vanish, and we don't see them again until he confronts Grodd.
When Lex approaches the vessel that Darkseid appears in, he appears to be no more than a few feet away from the vessel.In the following shot, he is several meters away from the vessel.
Trivia: The surviving Legion of Doom members with Lex Luthor at the end are Heat Wave, Toyman, Giganta, Cheetah, Atomic Skull, Evil Star, Bizarro, Star Sapphire, Sinestro, Killer Frost, and Volcana.
The number of Grodd and Luthor enforcers are split roughly in half between the sixty members, but when Frost freezes them, there's maybe ten that were on Grodd's side.
In the shot of the Legion at the end of the episode, the crack in Toyman's mask has disappeared. The crack then reappears in the next episode.
Lex: Well, Metron, I'll soon be able to handle anything the universe throws at me. I'm about to become a god.
Metron: You don't know what a god is, or what you are unleashing.
Lex: "Tampering with forces beyond my control," nice try. Look, if you want my power, make your move, otherwise you can get lost.
Metron: You will regret your decision, we all will. (Metron disappears)
Metron: We exist between two ticks of the clock. In my travels through the myriad paths of infinity, I have seen the first and the last, but what you do today threatens the entire universe; past, present, and future.
Luthor: I should hope it does.
Luthor: I've reconfigured Grodd's cloaking field into a hyper-spatial drive!
Killer Frost: You're not serious?
Luthor: Little bit.
Tala: I don't like to compete for Lex with a dead computer. I want you to be my man in charge, like before. So...baby...what do you want?
Grodd: Why, only you, my dear. And Luthor's fat head on a plate.
Lex Luthor: Wrong! I saw enough of those stars to determine the explosion's coordinates. It should be a simple matter.
Tala: You saw the wild goose again! Concentrate on us, baby! Space is too far! Together we can rule this world!
Tala: By the slaughter of the innocent...by pestilence and plague...reveal the hidden unto me...there. You see? Just a rock. A worthless piece of...oh?
Tala: (picking up Brainiac piece) This is the real trouble here before us. It's pure wild goose chase! Look, I will prove it. I will show you what is in there!
Luthor: Don't be stupid! This is science. What good is your sorcery? Unless you plan to turn stone to gold! Or maybe a frog!?
Tala: Such ignorance! Transmutation is what you want to do!
Luthor: Transmutation is... what are you waiting for? Do it!
Darkseid: Only the slimmest of chances has allowed me to overcome my death at the hands of Superman. But let the universe howl in despair for I have returned.
Grodd: This mutiny was so easy. The secret society hates you.
Luthor: Like they love you.
Tala: Darling! Grodd must have used mind control! (silence) Okay... maybe not. But baby, you don't ever doubt I love you, correct? I, I know I did something bad. I'm a sick person, you don't know what it's like to be me.
Tala: (to Luthor) Funny...you were never this much fun when we were together.
Grodd: Giganta...you're out of jail...how's your head?
Giganta: Pretty good...considering you tried to fry my brain!
Tala: (saving Grodd from Giganta) Don't get crabby, Thunderthighs, Grodd is mine now.
Grodd: Come to gloat at me again? I'm not some monkey in a zoo throwing...
Grodd: Why is my headquarters moving?
Luthor: (regarding Darkseid) We've got a little problem.
Darkseid: It seems I have you to thank for my resurrection. Though your world will suffer slowly, I grant you a quick death!
Toyman: Twinkle, twinkle, Brainiac, Tala's gonna bring you back!
Luthor: You'll be the mystic conduit that will siphon Brainiac's essence from the debris. I'll be able to reconstitute him from that energy. But I doubt you'll see it.
Tala: You planned this all along. Even before I...
Luthor: I'm a sick person too.
Luthor: Goodbye, Grodd. It could have gone the other way.
Grodd: It really could have, couldn't it?
Luthor: No, but why speak ill of the dead?
