Has he? Since the reboot he hardly interacted with Tim or Roy, for example. That`s like one of the chief issues with his fanbase.
Which he admits in the end. What more with Jason helping Bizarro afterwards.
The only editorial note I`m aware of is that it happens before issue #12 so feel free to show something more especific.
Unless it happens during the intial stages of RATHO, which I don`t belive it does for the most obvious reasons, Dick Grayson is well received because she and Jason already have some rapport here and there`s little reason to mistrust someone whom Jason welcomes in. This is evidenced further by Artemis only talking about Jay.
True, they have to carry somewhere else, I dislike it being too short.
We still don`t know how that will play out so I`m not going to debate something I don`t know how will happen.
Given it`s the same writer, he`s got everything to use it.
