I know my friends and I (and maybe you guys too) will sometimes have fake relationships going on, like if we get into a joking argument I'll tell her I want a divorce. (Usually several times, resulting in multiple divorces and no marriages.) Other times we'll talk about how I cheated on her because she didn't satisfy me emotionally, as I want children and she does not, etc. I do this with multiple people. I want the whole YJ team to talk to each other like this (jokingly) and have the JL members catch them. It doesn't even have to be to this level, maybe member A refers to member B as their boy/girlfriend/wife/husband. Maybe they just refer to other team members as "baby" or "dear" whenever their mentor shows up.

Batman gets heartily, heartily sick of Superman's attitude towards Superboy and decides to take drastic action - he takes the kid under his own wing and helps to train him alongside with Robin. Superboy ends up being part of the 'Batfamiy', with Robin sometimes calling him 'Bro' during YJ missions. And then when Superman finally gets his head out of his ass and comes to try to teach Superboy, he has to first pass the Batfamily's tests to see if he is worthy of Superboy. Because Bats take care of their own.

(Prompt: MtF anybody. I'd like one of our boys [here Robin] to actually be a girl, and nobody knows that and she can't "pass" like she'd want to, even if she gets ahold of hormones and is on them no one can tell some sudden difference.) "It's stupid. If she doesn't want to tell them, why does she want them to notice?"

Megan is given a great deal of advice on how to deal with Wally. All it does is remind her of the fact that nobody on Earth speaks like she does, and that her body is not her own.

Every villain has a favorite. It's practically a rule.

"You're fucking with me." Tim blinks up at his uncle – and he's never seen his uncle in full armor before, not in person. It's kind of daunting. "Please tell me you're fucking with me, spawn."
