Justice League Unlimited Season 4 Episode 12

When Luthor proposes an alliance with Brainiac, Brainiac says his alliance with Darkseid tells him to mistrust organics, due to the events of the episode "Twilight." But this copy of Brainiac was inside Luthor for years, and never entered into outerspace so how did he know what the copy experienced?

In Luthor's flashback , Brainiac shot a yellow beam at Luthor. But, in the original episode, "Ghost in the Machine," he shot a blue beam.

When the Justice Lord Superman hits the real Superman, he knocks him back into some kind of tank or vat. Superman falls to the ground clear of the tank but there's nothing on him. Then in the next shot for some reason he's crackling with blue electricity that fades away. None of the other counterparts cause electrical sparks when they hit their opponents, so why does it happen here?

When J'onn calls the Watchtower, Superman is to his left (audience right) and level with him with his head is about at the same height at J'onn's. In the next shot, Superman is behind J'onn and standing, and kneels down to put his head level with J'onn's.

When they're discussing what Brainiac will do next, Wonder Woman is to the left talking with Hawkgirl and you can just see Superman to the right of them. Then they cut to a shot of Superman with J'onn and Flash to his left (audience rigth). But then they cut to a long shot and suddenly the order has changed completely: Flash and J'onn are to Superman's right (our left), Green Lantern is next, and then Hawkgirl, then Wonder Woman, and finally Superman. When Batman says, "You want to bet Brainiac can't?", there's another small jump and Wonder Woman is now on Superman's left (our right).

When the tentacles attack Green Lantern, he starts stepping backward and the street behind him is clearly empty for some distance. But he takes a couple of steps backward, there's a change in shot...and suddenly he's backing up to Waller. Where'd she come from?

In the initial pan shot of the crowd, Vibe is standing next to the highly visible red-white Rocket Red. But when the crowd applauds, Rocket Red disappears and Vibe is standing next to Black Canary.

In the initial pan shot of the crowd, Fire is near Elongated Man. When the crowd start applauding, she's standing right next to Dr. Mid-Nite several yards to the left (our right) of her previous position.

In the initial pan shot of the crowd, Booster Gold is standing right next to Dr. Light and Metamorpho and Crimson Fox are nowhere to be seen. When the crowd start applauding a few seconds later, Dr. Light disappears and he's standing next to Zatanna, Metamorpho, and Crimson Fox, who were nowhere to be seen in the opening pan.

During the opening pan shot of the crowd, Dr. Mid-Nite is to Waverider's left (audience right) and in front of him. He's still there in the long shot when Superman disbands the League. But when Green Arrow makes his speech, Dr. Mid-Nite is appreciably behind Waverider. Then as Green Arrow continues speaking, in the next long shot Dr. Mid-Nite jumps in front of Waverider again.

During the opening pan shot of the crowd, Zatanna is nowhere to be seen. But in the long shto when Superman says, "While we had the best of intentions..." she can be seen in the foreground in front of and to Atom Smasher's right (audience's left), just behind Dr. Light.
