I will disagree slightly in that EVERY writer has messed up Jason since JW. Don't get me wrong, JW is my Jason homeboy and no one writes him as well but I think it was Geoff Johns who wrote him in Teen Titans and that was all perfectly in character for me, if not the epic that is Jason by Winick.
See, there is this thing about the VSE trauma that gets me: Jason has enough trauma. He has a father that was killed by Two-Face, a mother than died on him, some time on the street, a mother that let him be beaten in front of her, died, dug himself out of a grave, existed damaged on the streets for a year, came back to be 'rejected' by his father figure who then dies on him. If Jason has trauma, they may just be using one of those. This is what I'm hoping. I don't think so, but I'm hoping. There's so much to choose from!
