Due to copyrighting issues and the fact that WB was creating a pilot series for Aquaman, Mercy Reef, Aquaman and his rogues gallery are off-limits to the JLU team as of this episode. The villain "Devil Ray" is a replacement for Black Manta, one of Aquaman's villains and a member of the original Legion of Doom.

At one point, King Faraday informs the crew of Devil Ray's sub that they are surrounded by three Seawolf class attack subs. In the real world, the U.S. Navy has precisely three subs of this class.

Wonder Woman: I’m representing Themyscira at the global warming conference.
Green Arrow: Way to go, man - save the planet.
Wonder Woman: More like save my relationship with my mother.
Wonder Woman: It's the first thing she’s asked me to do since we've mended fences. I'd rather take another day trip to Tartarus.

Wonder Woman: Mr. Terrific can fill in. He's smart enough to do monitor duty and the Sunday Times crossword at the same time.
Mr. Terrific: Go ahead, J'onn - I'm already finished with the crossword.
Green Arrow: You did it in ink again, didn't ya?

Wonder Woman: You don't actually like humanity all that much, do you.
J'onn: I don't... dislike them.

King Faraday: By the way, if you raise your voice to the VP again, my men are under orders to shot you.
(Diana points at her silver bracelets)

Wonder Woman: (to Giganta) Out of my way, Jumbo!

Killer Frost: (to Wonder Woman) Cheater! You're cheating...

Devil Ray: It’s a poisonous stinger, sweetheart. It will kill you, eventually… slowly… painfully. But today is your lucky day. I’m gonna put you out of your misery right now.

Killer Frost: (to an F.B.I. agent) You’re a beautiful man. (freezes him) I think I’ll keep you.

Green Arrow: And Black Canary said a buzzsaw arrow was self-indulgent.

Thug: What are you doing in here?
Green Arrow: (punches him) Well for one thing, it's freezing outside.

Killer Frost: (to J'onn) Let me go, freak! Or so help me I'll give you frostbite in places you didn't even know you had places!

J’onn: You’ve done well.
Killer Frost: Kiss my frosty butt.

King Faraday: While I strongly suggest you surrender immediately and prepare to be boarded, I really enjoy firing Trident missiles at tiny little subs so the decision is entirely up to you.

Who is filming all the League missions for the monitoring screens? And how can the cameras go along with each Leaguer and be on them with such close-ups?

Wonder Woman says she can use her Lasso to get the Legionnaires to reveal why they want the vessel, but the Lasso is never visible nor there's any sign she has it on her.

How could Green Arrow use his bow to slide down a cable and then jump off from it with the bow still in his hand?

Faraday threatens to fire "Trident missiles" at the enemy sub. However, he is a sub and Tridents are missiles which are fired from subs into the air, not to another sub at a close range.

Poem that Wonder Woman Reads
The poem Wonder Woman reads toward the end of the episode is "The Rime Of The Ancient Mariner" By Samuel Taylor Coleridge.

Wonder Woman's Transformation

Diana’s spinning and consequent transformation into Wonder Woman is a nod to the Lynda Carter Wonder Woman series, where she did the same thing to change into Wonder Woman.

"The Balance"

Wonder Woman: (about Hippolyta) It's the first thing she’s asked me to do since we've mended fences.

"Comfort and Joy" and "Starcrossed (2)"

J’onn shapeshifts into the same human form he bore in previous episodes.

The closing credits feature clips of the upcoming episode "Flash and Substance."
