Define retcon here, will you? As far as I know, DitF is the way it "really happened." It's just that later comics seemed to paint it as, you know, Jason's fault. Was there something I missed?
(I guess you could SORT of argue that him running across the world w/out Bruce fits into the "being stupid" catagory, but Batman DID find him well before the dying, so... yeah... *shrugs*)
