I could see him doing the same thing Bruce did, traveling the world, learning from different martial and philosophical schools, then returning to Gotham with his anger focused and his body and mind a machine made for fighting crime. Only then could he hope to compete for the Cowl, but he'll no longer want it, he'll have his own thing to do. oh wait it's been a while since i read UTH so i forgot but they already had him do that didn't they
Well, why they gotta retcon crazy into his background? They could've just said the Lazarus Pit did it. I still want to see him wash up at Nanda Parbat or something (because gotham harbor definitely goes that far, nanda parbat is certainly on the waterfront, and jason could easily survive floating IN AN OCEAN for weeks, months) and learn to not be crazy anymore.
