So Heretic killing him didn't leave a scar. Bruce stabbing him back to life didn't leave a scar. Jason's ass whooping didn't leave any scars. But Flatline pulling a Killua on him did xD
And in typical Damian fashion, he was not the least bit humbled by this defeat. Dude immediately wanted a rematch. That's my son lol
