Okay, first thing. I don't think Leslie Thompkins *should* have killed Stephanie "Robin IV" Brown as some sort of warped point to Bruce about the dangers of costumed vigilantes.

I think she should have done it and NOT have it retconned away. I think this should be a VERY painful thing for Bruce, Tim, Alfred, Dick, Barbara and pretty much everyone in the Bat-family who knew, respected and trusted.

Tim, most of all, should say things like "I want to wave a magic wand so this never happened... but I can't."

Basically, Leslie killing Stephanie through deliberate lack of treatment is a bad thing. And bad things happen. And, time travel and Infinite Crisis notwithstanding, they can't un-happen. Leslie killing Stephanie should stay one of those things *because* of the rage it caused us all as fans.

They can really go somewhere with this, especially in Robin's book. What if Leslie is captured or turns herself in? How will the Bat-family react to that? How will Stephanie's father, the Cluemaster, react to that? I'm pretty sure I know how the Joker will react: "How DARE someone else kill Robin? *I* kill Robin! IT'S MY THING!!!"
