Trapeze artists Dick and Jason.
Just imagine Haley's used to be about two families marrying together due to financial reasons but over time other issues started to rise and a generation and reaching European fame later they separate again.
Both keep the name because it's already famous and start touring on different sides of the continent.
The Haley's with the Grayson family becomes much more famous and starts touring around the world while the other Haley's stays mostly in Europe or Middle-East.
Generations are passing by and not many remembers the connection anymore, those who do only use it for marketing purposes so when the Graysons die Bruce doesn't even think about looking into the rumour about things hundred years ago.
Even if they were true the two Circuses haven't interacted in many years so it wouldn't be relevant and maybe he really wants to keep little Dickie.
Then comes the Court of Owls and nothing leads back to the other Circus in Europe because the deal was made after the separation.
Then one time Dick needs to go undercover, maybe agent 37, but the point is that he sees the other Haley's and after the mission he goes back in hopes of seeing the place he considered his home and what he didn't have anymore.
Maybe it's self-blame or curiousity that leads him to the show but he sees it and it has a very different program so he gets a bit sad, maybe it's better this way, until the trapeze artist comes on and it's nearly the same routine.
He watches intently and feeling just like a kid when he used to see his father practice his part alone than.... there's nothing, there's no part for two people.
His heart aches because he can't stop seeing the part where her mother would have jumped and caught his father's hands with love and admiration on her beautiful face.
Maybe that's why he went to find the artist. He walked through the river of people he so enjoyed getting lost in, stopping to give a pat to the friendly elephant on the way to the back.
He asked about the show and turns out they only had one trapeze artist and the trapeze. The artist wants to teacher a young couple who were brought up in the Circus and would like to take over, but they would need a pair to safely show them how to do so.
Dick wants to help but doesn't know how to. Pairs need to work together for years and trust or at least know eachother's moves and style, he couldn't do it with the old artist. There isn't anyone who would know the routines, it was only him, his mum and dad, and Jason.
Jason. He had taught him when he had given him Robin. Robin meant his family and he wanted to fly with his family again so he taught his first little brother and Jason wanted to be able to do it so much, he wanted Dick's approval so deeply he practiced until they could move in sync and do it together.
That night his fingers hover over the call button, than around three he makes the call.
Jason doesn't understand why he needs to go to some small European city where even the trains don't stop but begrudgingly agrees to go just because Dick rarely asks for help.
Two days later he stands in front of a Circus tent? and suddenly sees Dick in a God awful uniform, like it's really horrible, showing nearly everything.
After Dick explains everything -no the clothes are absolutely unexplainable and is it really neccessery?- he is floored. He travelled to the middle of nowhere so Dickie could play pretend with him, again?
-Pray tell, why can't the pretender do it?
-Because he doesn't know do routine.
-Why? Didn't you teach the new birdies how to fly?
- It was a family tradition, to teach the younger ones. After failing Robin, failing my little brother I couldn't do it again.
And Jason is a weak man to those puppy dog eyes, even if it's a twisted kind of logic and Dick is nearly thirty, he couldn't say no.
So they start to practice again. They spend most of their time on the trapezes, when they don't practice they argue or talk to the people of the Circus.
Dick seems to be happy and Jason really enjoys getting to know all the culture and traditions braided into each other from all around the Globe.
After a few weeks they start to train the new couple. It's harder for first timers but they are learning fast and Dick and Jason gets closer to each other, finally talking instead of shooting and not having the place to run away for a long time it gets easier.
The night before the couple's debut they both find their ways to the training ground, Dick frantically checking the ropes and trying to make them strudier, trying to rewrite history, Jason worrying about his big brother who has given him something special.
They make the routine a final time. As the light shines on them being in the otherwise dark tent Dick can imagine how it was doing the same jumps with his family, now two decades later doing the same thing.
He can feel the faint smell of popcorn and dust and leather with chalk. He can hear the breaths breaking and faintly see someone cover their eyes in the coat of their loved one, feel the grip on the tape on the metal bar and he jumps.
He is flying again, it's different than on rooftops, it's a different kind of adrenaline and freedom, it's his life, it's what he had shared with a smiling little kid who was so happy to be considered part of the family, the same smile looking at him now and opening his hands to safely catch him.
The next night the new couple shows up on the stage in the air and gets to experience it for the first time. They don't talk, they don't tell on each other for crying, they don't wait until the end of the show.
They go home to Gotham and don't tell the others, it's their little secret now, one that can continue living on because of them.
If they ever go back nobody knows, if they ever disappear for a few hours nobody knows, if they donate anonymously nobody needs to know it either.
"Would you really tell on us Barbie?"
O: At least they are getting on now.
