It had been four years. Four years without you. Why? Well, because you died.
....Kind of.
You were part of the Bat Family, maybe not the smartest or the fastest, but one of the most appreciated. And maybe it was the pressure. Or maybe it was the villains. Or maybe it was the city, even. But one day you leapt from one building to another and didn't make it.
It looked like you pulled short. It looked like you didn't even panic as you fell from the office tower. It looked like you didn't even try to get back up. But Damien refused to believe that was true. Even Barbara couldn't fathom a reason why that would be true.
Four years later, life went on. Not without remembering you, though. Just a few weeks ago they had gone to an annual memorial to your tomb to mark the date of your passing. It had taken so long for them to accept that you were gone, though.
