My annoyance with this scene stems from how much leeway Bruce is giving Jason vs. how he kept saying the Huntress is too violent and grimdark to be in the Justice League or part of the Bat-family.
As Bruce didn't know about Jason crawling out of his own grave and being affected by Lazarus Pit Crazy Juice from BATMAN ANNUAL #25, Dick and Co. are a little out of their depth. As we don't seem to still have the INFINITE CRISIS "Batarang in neck" scene, maybe Jason's whole "I'm furious because Batman didn't kill the Joker" motive doesn't enter the equation.
Some of Jason's "painful secret" might refer back that fight/discussion between Jason and Mia in GREEN ARROW #72. Jason told Mia "You and I are from the streets, for reals, dawg." And Mia was a teenaged prostitute.
