Hear me out.. Bernard and Tim adopt a kid who was from the cult of Dionysus. Like.. imagine. Those two, as parents. But they won't fully admit it yet, and just move the kid in their boat house. Fully treating the kid like their child, and just living life. Maybe with a few cult attacks or whatever, but they don't make the connection until someone from the batfam bring it up. And they start rethinking their dynamic.
*Bonus if the kid ends up meeting Lian.
