Maybe if there’s a big enough jump forward, the final shot of the series featuring Bruce as Batman could also feature a Robin.
My big question at this point is whether Gotham will deliver a very early version of Batman, since even after the upcoming time jump, Bruce will still be a teenager, or if Gotham will put Bruce in the cowl after a time jump of many years.
Surely those Graysons got to procreating sometime after their happy ending back in Season 1!
