Maybe I'm happy about my headcanon being put on page and I'm not thinking it through. I'm willing to allow for that. But isn't it more likely than "shrugging off" killing attempts that those issues (and the Teen Titans issue where Jason shows up in the canary yellow tights) never happened in the DCnU? So there would be no need to shrug them off, because they just didn't exist? Johns's run on Teen Titans obviously never happened in the new canon, just judging from what we've seen on the page and even ignoring what we've heard in interviews and stuff. I've seen no evidence that Tim's old Robin book is canon either. So if none of that is canon, then it can't be taken into account and removes a lot of the problems you listed. Doesn't it?
