I'm happy with all this.
Damian refusing to believe that Bruce is dead. It makes sense after the last time when Dick went to London and found out he wasn't actually dead instead was lost in time.
Damian and Jon having a fall out makes their friendship more believable. It can't be sunshine and roses all the time. that boring.
Happy to hear how much he has enjoyed writing Damian. It seems it's a labour of love. I hope the title continues to sell.
