People needs to accept the fact that NO ONE WILL EVER KILL THE JOKER. Is just not profitable and DC is first and foremost a business, so hanging into the idea that Jason shouldn't speak/work with Bruce due the Joker being alive is delusional and clinging to a creative dead end.
Saying that Jason is NIghtwing with guns is frankly dumb and only shows that people hasn't bothered to read RHATO or Pak's work with Jason. Other than the mandatory crossover of the past few years and the massive trainwreck that Tynion's run was, Jason hasn't acted with the Batfamily at all on his title (hell, RHATO was even moved to the JL solicits this month), Pak wrote Jason and Bruce relationship as one of convenience with Bruce looking Jason because he was willing to do the dirty work. Eternal is a trainwreck where everyone is out of character but thankfully Jason has been written off it for the time being.
Roy and Kory are so different on the N52 and their relationship with Dick is so insignificant that is also absurd to get hung up on the "but the are Dick's friends" mindset. And finally, let's wait for Jason to show on any other media first before playing the "Under the Red Hood" depiction card.
