It was in the Harley and Ivy story in DCs love is a battlefield issue. The Batfam appear in one of many flashbacks of Harley and Ivy recounting the 'good old days', I don't know if the rest of the Batfam are at grandfather/grandmother status just yet in that one but it is in the future and Bruce is depicted as older. Jason also showed up in
Harley Quinn White Knight #5, though it's a quick, unmeaning appearance, nothing to pay attention to yet if people are waiting around for him.
I'm glad to see Roy is definitely back in Infinite Frontier, and regarding the name drop, honestly I'm just surprised that Roy and Jasons relationship is still being acknowledged at all, especially after quite a few reboots or soft reboots or whatever in between their short duration together. I mean, DC even had him let go of the trucker hat so they're clearly listening to what the fans want XD. Perhaps the Roy and Jason bromance was more popular than I had initially given it credit for? Or perhaps since Jason is a little more popular now than he was even back when New52 had started, it felt reasonable to keep that relationship thread going for future titles, just in case? Though truth be told, I'd rather see Roy either in his own title, or in a Green Arrow title that could rebuild his relationship with Ollie a little more. The Arrowfam needs a little TLC.
Also I haven't seen anyone mention the
Infinite Frontier group shot poster, I saw people mention that Red Hood was on the image but couldn't spot him for a good minute. My eyes were roaming all the little characters in the background, I'm so used to being on the lookout for Red Hood within the background of these kinds of shots that I absolutely missed him being right in the front this time. XD
Though I suppose the lack of an actual 'Red Hood' on his outfit didn't help the search. Seriously can we get the helmet back now?
