I enjoyed Jason slowly taking responsibility for his brothers in the wake of Bruce's bad parenting.
Jason doesn't think much of it when Tim needs his help, or Damian moves in, or even when Dick turns up looking beat all to hell. But at some point he realizes that he might be the best option his brothers have to recover from the cycle of violence that Batman has set up, and all he can think is that things were much easier when he was the villain.
