Trivia: J'onn mentions his security code as being 004, presumably making him the fourth highest ranking League member.
When the camera shows Galatea dropping the weights, the water bottle is on the audience's left edge of the crate and the towel is lying across the middle. But when the camera cuts back to a shot from Tea's direction, the water bottle is in the middle and the towel is lying on the left side (what was the right side from the other angle).
When Huntress reaches for the oxygen mask in the infirmary, the Question's overcoat and the chair it's hanging on are nowhere in sight. Then when he tells her to get the aerosol, the coat and chair appear in the next shot.
Superman: Get Question out of here – don't wait for me.
Huntress: What made you think I was gonna?
The Question: You were right - I am the ugliest guy of all time.
Huntress: Not in my eyes.
Superman: I can shut down Cadmus without killing Luthor.
The Question: Carry on, then. If you're wrong, it's not like it's the end of the world. Right?
Superman: Give me one good reason not to go down there and take (Cadmus) out.
J'onn: If you didn't know the answer, you wouldn't have bothered to ask.
Green Arrow: Batman said I was supposed to keep you guys honest.
Superman: Do I look like Batman to you?
Flash: Actually you kinda do, especially when you're all scowly like that.
Flash: Grammy Flash always used to say the trouble with "an eye for an eye" is that everybody ends up blind.
Green Arrow: We did this.
Flash: No, we didn't. You saw, somebody took over the controls.
Green Arrow: It's our gun. If we didn't have it they couldn't have used it. It's too much power for anyone to have.
Green Arrow: I'm not sure what I'm doing here anymore.
Flash: People need us – we help them.
Galatea's suit resembles the character Power Girl from the comics, except she's missing the small red cape pinned to her left shoulder. But when she tosses the red towel over her shoulder after weight lifting, the image is complete.

The Flash rescues a yellow cat with green eyes, which promptly attacks him. This is an allusion to the cat Power Girl has in the Giffen/DeMatteis-written Justice League comics from the eighties.
