soulmate au where soulmates are rare but they are always a tragedy, an all encompassing desire for the other, the need to consume them, driven to rip them apart until there's nothing left and then you're left with an aching loneliness and loss bc your very reason for being is gone
i'm thinking JayTim but DamiTim could also work (also HarryMort, bc somehow almost nothing changes from canon)
"We have to keep them apart," Dick said. Bruce sighed. "Bruce!"
"Dick, no one has successfully kept soulmates apart from each other, ever," he looked out the window to see how Jason was looming over Tim, who was pushing into him. It would be cute if you didn't see how bloody Tim's hands were from holding onto Jason; the cuts on the bigger man were obvious. The bruises on Tim from where he'd been held could be seen, too.
"They'll kill each other," Dick said, unable to accept the fact the men he felt were his brothers couldn't be saved.
"I know," Bruce said hauntingly. His hand went to his wrist, where his own mark was. Dick flinched and looked back at the two.
The Joker was the hanging sword above their heads. The reminder that Bruce understood soulmates on a much deeper level than Dick. Dick had never actually met any soulmates before. Not until he saw how Joker and Bruce acted around each other. How Jason and Tim reacted.
His mouth tasted like vomit. He'd found the crime scene of a soulmate couple's final moments. The man had been killed by the woman who hung herself after. The cops shook their heads, knowing there was no big mystery.
Dick didn't want to walk into a scene like that but with his brothers.
(But he probably would.)
