Curate, connect, and discover
Gothamites have aliases. It's something that doesn't make sense to outsiders, but it's true. Parents usually give their children an alias as a birthday present between the ages of 5 and 10.
Jason's revival isn't new in Gotham. Minor revivals happen all the time. If they didn't, Gotham would be a barren ghost city. The thing is, these minor revivals take years off your life. So all the kids and teens that died in Joker's attack on a school? They are now adults and teens. Can't go back to your old life? Here's a new identity!
All the dumb grunts getting hired by villains? Kid's who died too many times to get much out of school. They don't have the education to even try for a regular job.
All the homeless people, kids especially, on the streets? Teens and adults revived from kids who never got to learn where babies came from until they got slammed with hormones and couldn't deal with the consequences.
Most people in Gotham have died at least once privately, some publicly.
Jason was living on the streets after suffering under abusive Willis and drug addict Catherine Todd when he got picked up by Batman. You bet he died at least once.
Bruce's parents died? They gave up their revivals so Bruce could still have something of a childhood, cause you bet he died there.
Tim lived alone and unsupervised for most of his childhood? You sure bet he died. Was he also surrounded by the cursed objects his parents brought home? If this boy didn't have frequent encounters with questionable beings, I would be surprised. (Low key suspect he came out immortal and pulls stupid stunts regularly to 'grow up' with 'growth spurts'. Forever 17 Tim Drake has a reason, now.)
So, they all have aliases. The Wayne's and the Malones and the Drakes and the Cobblepots and everybody.
And this means that will readings are a pain the ass to everyone not from Gotham, because by the time Final death comes, you've got at least 3 aliases you need on your will for it to be legitimate.
