[DC] Bruce Wayne is an identical twin, both surviving witnessing the death of their parents. How does growing up with an identical sibling who shared the same experience and trauma impact the timeline?

The way the DC universe operates?

Bruce still has all the baggage and trauma from that night, and in any ordinary circumstance having a sibling at all might help them work through the trauma together.  But his twin, Bryce?  He reacts entirely differently.  Bryce wants to help, but Bruce is entirely withdrawn, responding to nothing but his rage.  Bryce does everything he can to cheer up his brother to no avail, pulling out all the stops.  Harmless pranks.  Funny faces.  Jokes.

One otherwise ordinary day, after years of trying to reach out to Bruce - and in turn, calling out for his own help and support - Bryce starts laughing.

He doesn’t stop.
