It’s never a good idea to get on the bad side of magic users.
Batman got to learn it first hand when he was talking to his fellow league members only to have them look shocked or confused. Some asked him to repeat his instructions. When he updated Green Lantern about the situation in Metropolis, the man laughed in his face, clapped him on the shoulder and congratulated him before walking away.
Soon, word spread around the Watchtower that orders were being sent down from or given to a mysterious associate of Batman. This person would go on missions, assist the league members and more significantly, they were of crucial importance to Batman.
Eventually, Zatanna heard about his situation and offered to help remove the hex.
“Yo Spooky, I’ve sent the updated coordinates to your dearest hubby’s comms!” Hal yelled down the hallway and quickly disappeared around the corner.
“Bruce, looks like someone played a prank on you and altered the audial perception of the word Superman to “My husband” whenever you utter it.” Zatanna said, visibly trying to hold back her laughter.
Batman shared a glance with Superman. “Can you remove it?”
“Sure, it’s a pretty simple hex. But you’re both not mad about it?” Zatanna asked.
“Well, to be honest, I didn’t notice anything different about Bruce today,” Superman replied.
Batman: There are no signs of sentient creatures living on this planet, or anywhere else in this universe.
Superman: [looks sad] Oh.
Batman: But take a look at this. [shows him a microscope] I’ve discovered a pair of protozoa.
Superman: Oh thank god! We found this universe’s Bruce and Clark.
Batman: …They’re microorganisms, Clark.
Superman: Well I just know that we’ll always be together in every universe, no matter the shape or form.
Batman: [looking through the microscope and seeing one of the protozoa inch closer towards the light while the other stays away] Hn. I’ll bring them to the lab for further study.
Clark: Bruce, can I ask for a reaaally tiny favor?
Bruce: What is it, Clark?
Clark: How do you feel about a new addition to the Cave? You know, since it’s mostly just you and Alfred. Alfred wouldn't mind some extra company, would he?
Bruce: Alfred enjoys his peace and quiet. Now spit it out.
Clark: Okay, okay! I found a little bat earlier today. He seemed injured and his wing was probably clipped by a car. I patched him up at home, but he needs a safe place to recover. You have plenty of... uh... "bat-friendly" facilities in the Cave, right?
Bruce: My facilities are for surveillance and crimefighting, not wildlife rehabilitation.
Clark: Come on, Bruce! Look at this little guy! [shows him a picture of a fluffy bat with a bandaged wing on top of a Batman pillow]
Bruce: ...It is rather small.
Clark: See? You won’t even notice him! He'd be right at home with the other bats. They can be bat buddies!
Bruce: My "bat buddies" are not pets, Clark. They are wild animals that I try to maintain a respectful distance from.
Clark: Pleaaase? Think about how scared this bat will be out there all alone! He’s just a baby, Bruce! And an orphan.
Bruce: ...
Clark: ...So?
Bruce: ...Fine. But if this bat crashes into my monitors, you're taking full responsibility.
Clark: Yes! Thanks, Bruce! You won't regret this. BB is a very well-behaved bat, you’ll love him. He’d make a great bat spy one day!
Superman struggles to conceal his emotions from Batman. His eyes, much like a mood ring, change hues based on his feelings, a trait he can’t control. Batman, with his sharp observational skills and perfect score in the Farnsworth Munsell 100 Hue test, seems to pick up on every subtle shift. Despite his efforts to remain composed, Superman feels exposed under Batman's scrutinizing gaze, his eyes betraying his inner turmoil with every glance. It becomes increasingly challenging to maintain the facade of stoicism, knowing that Batman can see right through him. It doesn’t help that whenever they have a serious talk, Batman holds his hands with a thumb lightly pressed on his wrists to gauge his heart rate as he stares directly into his eyes.
During a battle, Superman and Batman were struck by a beam from Mister Mxyzptlk, fracturing their personalities into three separate entities.
Bruce ended up with Batman, the aggressive dark knight; Brucie (or Wayne), the smooth talking playboy; and Bruce, the awkward loner.
Meanwhile, Clark got split into Superman, the symbol of hope; Clark Kent, the mild-mannered but persistent journalist; and Kal-El, the alien longing to be accepted.
They had to live together until they could fix things, and surprisingly, the Clarks got along great. But the Bruces? Total chaos. Batman's always raging, especially at Brucie and that "reckless, overly-righteous" Superman. Brucie's busy flirting with anyone with a pulse, making Batman super uncomfortable. And then there's Bruce, who's avoiding everyone, especially Batman.
Living together forced both Bruce and Clark to face some deep issues they've been hiding, and they ended up understanding themselves better. Batman and Bruce had long heart-to-hearts about their fears and traumas, opening up emotionally. Clark learned more about the real Superman behind the hero facade, seeing the heavy burden of responsibility and Kal-El's loneliness.
Batman started to let his guard down around the sincere Clark, who wasn't fazed by his grumpiness. Superman figured out there's more to Brucie than meets the eye and saw that he was secretly struggling to prevent Batman and Bruce from succumbing to rage or despair. Kal-El, wanting to get closer to Bruce, had to deal with Batman's protective streak first.
Barry: Hey Clark, we heard about your recent breakup. Really sorry to hear that, man.
Clark: [gloomily] Yeah...
Bruce: [stares out the window]
Arthur: You will meet someone better suited for you one day—your destined soulmate.
Clark: I hope so.
Bruce:
Hal: I mean, who wouldn't go for you? You're strong, smart and handsome!
Clark: Thanks Hal.
Barry: Yeah! I’m sure you'll meet someone who's just as kind and attentive and knows how to cheer you up whenever you're feeling down.
Clark: Mn.
Hal: Hey, there's this new bar that just opened up in downtown Metropolis! We should go and check it out this weekend! Whaddya say?
Arthur, Hal and Barry stare expectantly at Bruce.
Bruce: [slowly turns to look at Clark] I like the look of your bleeding heart.
Arthur, Hal & Barry: ???
Clark: [visibly cheers up] Thanks Bruce! You know, it took a few attempts to grow those flowers in outer space, but I finally got it right! They look slightly different from those cultivated on Earth, but I find them unique. I'm glad you like them too!
