#both works

medschool!rabbot fooled around but never went too far, both too scared and confused, now in later years they never talk about it because both of them think they've missed their chance with each other or they just assume the other one is actually fully straight +Robby can't imagine replacing Jack's wife

After meeting Childe:

Traveler: "No, I just... I don't get it, I suppose? You're never usually this hostile, even to someone on the opposing faction. Cold? Sure yeah, that's nothing new. Hostile is a new look on you,"

Kaeya: "...You've heard of the incident that resulted in my father's death, right? Adoptive, I mean,"

Traveler: "Well- yeah... I have. Fatui's doing. I get that. It's just- You're close friends with a god that aided in the massacre of your entire bloodline. I just didn't peg you for the type of guy to hold that kind of grudge,"

Kaeya, laughing a bit: "I suppose that's true. It wasn't Venti's fault for Khaenri'ah's fate and I can tell he carries a heavy guilt regarding it. I don't see the need to hold it against him. Sounds tiring,"

Traveler: "Then why is Childe different? He's basically the same age as you, meaning he would've only been in the ranks for a short while, let alone play any role in your- uh. Your father's incident,"

Kaeya stops walking causing Traveler to pause as well.

Kaeya: "...Well."

Traveler: "...?"

Kaeya: "What if I told you he just rubs me the wrong way?"

Traveler: "...What do you mean?"

Kaeya: "There's... Something about him. It screams familiarity but in an uncomfortable way. It's like he knows something about me that I don't want him to know," he grimaced. "It's gross. Feels like my skin crawls every single time he glances at me,"

Traveler: "You know what. I get that. His eyes are pretty... Dead,"

Kaeya: "No kidding."

Traveler starts walking again

Traveler: "But... I hope you can trust my judgement on this. He's a good guy,"

Kaeya: "He's a harbinger."

Traveler, wincing a bit: "Okay fair. But he's not as bad as people make him out to be. Underneath all that bloodlust and craze and world domination, he's actually a pretty normal guy,"

Kaeya: "That's a lot of things to look past, traveler,"

Traveler, smiling: "You'll see it once you get to know him,"

Kaeya: "I find that I don't want to do that, actually. I prefer my relationship with him to be a professional transaction,"

Traveler: "That's fair too. Just tolerate each other, yeah? I need this domain cleared without any of my friends' abdomen being impaled by each other,"

Kaeya: "If that's your request, you know I'll always oblige,"

Y/N: Since your mouth’s so dirty, why don’t you wash it with soap?

Believing you are so clever, blind to everyone’s reaction.
