- In the Search for K, Superman falls to his knees in despair when he and Batman found out that the squad armed with krypotonite weapons out for Superman's blood was created and funded by the US government itself (surprisingly Lex Luthor isn't involved). They didn't care about Superman's devotion to protect people and they wanted him dead. Batman then snaps Superman out of it by telling him that he believes in him.
- Issue 50, aptly titled "The Fathers", revealed that Superman's father, Jor-El, had met Batman's father, Thomas Wayne. Jor-El explains that Krypton will explode soon, so he is trying to determine which planet would be the best candidate to send his infant son to. He has already interviewed people from several other worlds, and Thomas is the latest one. I will paraphrase this part, since it's been a while since I read this.Thomas: I have to warn you that Earth people are not perfect. We have a tendency for misusing our gifts for war and personal gain. But I assure you, if I find your son, I will raise him and love him as my own along with my own son.
Jor-El: (smile) That's what I was waiting for. (the other candidates had offered knowledge, glory in battle, living like Gods... but never mentioned anything about love)
- Later on, Clark and Bruce talk about how Batman relies on the success of Wayne Enterprises, which in turn stems from the technology from the probe Jor-El sent, and how Kal-El would never have been sent to Earth if not for a decent man who found it. Then, in their respective monologues, they think about how the other is the closest thing they have to a brother. Here it is◊.
- Issue 76. All of it. Clark is obviously shaken over Bruce's death. Before his funeral, Clark tells Lois that nobody will be wearing uniforms. He doesn't wear his glasses. Then, he thinks about his father, whose death he could not stop it, seemingly blaming himself for Bruce's death, and showing how much he cared about Bruce. But the Heartwarming Moment is when he talks to Diana after lashing out at Dick Grayson, who had taken up the mantle of Batman. He says that it's sad how the two will outlive their friends and loved ones, and he questions what he'll become when he's lost too much... Diana can see that he's just trying to rationalise this, and tells him that the truth is, He just misses his friend. Clark then goes to apologise to Dick, and they talk about Bruce Wayne, and how the two were the only ones that truly understood him. Superman says that he and Dick won't always agree. After all, that's what always happens when he works with Batman. Queue manly handshake and Manly Tears from the reader.
- Especially since this moment was foreshadowed in Justice League of America #0, which was all about the relationships that the Trinity had with each other, through the highs and lows.
- In Superman/Batman Annual #5 -during the Reign of Doomsday arc-, a computerized Dr. Fate tells Supergirl that she is suffering from survivor guilt after losing her parents and Krypton over again◊, she shouldn't let guilt kill her◊ and she has to forgive herself◊.
- In one issue.Superman: You fight against Joker, against Two-Face, against Catwoman. But this...
This is what I fight for.
