So... Ghosts are made of ectoplasm and emotion. And one of the ways a ghost generates the ectoplasm they need to continue existing is through emotion.
So in theory, ghosts could heal eachother by ANNOYING eachother.
Thus implying:
Jason: Ough. Tired.
Danny: Last assignment really took it out of you?
Jason: Yeah. I just feel drained as hell. Maybe I'm gonna go take a nap or-
Danny: Mathematically speaking, some infinities are larger than others.
Jason:
Jason: Fuck you. Fuck you, and your math, and your stupid technicalities, and your-
Jason: Wait, why do I feel better
Phantom and Red hood screaming profanities at each other. Then people who know (other heroes they work with) claim they are the closest friends but imagine if everyone else in the world, villains included, think they hate each other’s guts. Like the personification of ‘kick you while you’re down’.
Then Harley Quinn walks in on the making out sloppy style and records it for the internet, confusing villains and civilians everywhere.
Making out also raises your emotions. Just different ones 😎
Now no one can figure out if they're actually together, or are just using that as another way to feed. (it's both)
Danny throws Gotham for a loop by making the Red Hood a bottom.
Nobody expects the big muscular crimelord to be a massive fuckin' sub. Or the TINY space nerd who exclusively wears hoodies that go down to his knees to be a dom top.
And yet, Danny has Hood's legs around his waist, and VERY MUCH has him pinned. Jason is significantly vocal, and is clearly into it. His neck is fucking COVERED in lovebites. Danny is just holding Jason up, entirely on his own strength and making him whimper.
It goes fucking viral before getting taken down due to being too explicit, and Bruce gets to know far more than he ever wanted to.
