Damian [about Jon]: He’s the worst person I’ve ever met. I want to fight crime with him.

Justice League’s Got Talent be like…
Bruce [to Clark]: I’m a judge, so I don’t want to seem partial, but Jordan will win this over my dead body.
On what happened to the Batcave after “Final Crisis”…
Clark [to Bruce]: After you disappeared, it was closed for sentimental reasons. And also asbestos reasons.
On the kinds of people he lets into his life…
Bruce [to Clark]: You’re not even close to my type. I mean, you’re a complete boy scout and you make me crazy most of the time. You’re also the best person I think I’ve ever met and you’re the best friend that I’ve ever had.

Now, Bruce, was that so hard?
Clark: Bruce called me for a reason. I don’t think he’s happy.
Dick: No, Bruce’s happy. He’s just grumpy all the time.
Why you should try not to take anything Batman says too personally…
Batman: I can’t afford any more delays, Clark, and you’re one of those superpowered beings who cause delays. Sometimes it’s a good thing. There’s a whole group of heroes. They’re “delay heroes”.
Superman: *quivering lip* You mean… You mean you don’t like me?
Batman: No, of course I like you. It’s because I like you that I don’t want to be with you. It’s a complicated emotion, Clark!
World’s Finest Dads…
Batman [about grounding Robin after a mission gone awry]: I promised I’d never let anything happen to him.
Superman: Hmm. That’s a funny thing to promise.
Batman: What?
Superman: Well, you can’t never let anything happen to him. Then nothing would ever happen to him. Not much fun for little Robin.
Clark: Are you ever afraid?
Bruce: No.
Clark: Not even of dying?
Bruce: No.
Clark: You don’t feel any emotion about it one way or another?
Bruce: No. I have to stay functional until my mission is complete. Then it doesn’t matter.
Clark: Yeah. I have to stay functional, too. I’m “too important”.

Because the dialogue between a cyborg assassin and his human protectee fits Bruce and Clark just fine.

Imagine: Bruce’s response when Selina tells him that cruel-and-tyrannical-Injustice-Clark could crush him.
When Clark met Bruce…
Clark: You travel a lot?
Bruce: Yeah.
Clark: Traveling makes you lonely?
Bruce: I’m alone, I am not lonely.
