- When Superman saves Zatanna from the vacuum of space and revives her with CPR.Zatanna: Sknaht.
Zatanna: (with tears in her eyes) I meant, thanks.
- When Black Manta orders his minions to execute Aquaman's infant son, only for them to stand together and defy him.
- It helps that Aquaman destroyed the mind control equipment he had on his backside.
- Captain Marvel coming to Superman's aid definitely counts, particularly once you consider that their last - and arguably most famous - major encounter was in Kingdom Come, where the two fought one another. The scene is even a mirror of the Kingdom Come moment, but instead of the Captain standing over Superman, ready to fight, he extends his hand to a man who could really use it.
- Jean Loring sat next to a fatally wounded Ray Palmer. She initially wanted him to quit being a superhero, but more than ever she wants him to come back to her. Much more heartwarming, despite what happens between them.
- The Phantom Stranger snaps Hal Jordan out of a hallucination, then actually hands him his power battery so that he can recharge and fly back to Earth.
- When Superman meets Lois Lane again, he kisses her passionately while his cousin Supergirl -who disparaged Lois while she was mind-controlled- beams at them.
- The scene where the heroes are reunited with their rescued friends and loved ones. If you look closely, you can see Steve Trevor embracing Wonder Woman despite her condition.
