The bird buried in the backyard belongs to no one

Jason Todd-Wayne dies at fifteen. He doesn't come back. The world moves on.
Bruce adopts more children, they don't even know his name. No-one talks about those three years between Dick and Tim, the memorial in the batcave, or the old kids drawing stuck to the fridge with a bookfair magnet.
But the creak in the library floorboards remembers, the flickering lights, and the chandelier they've had to replace three times. The boy Duke Thomas find sitting on the roof on his first night at Wayne manor remembers too.
