Third arc: Nightwing works with Gaucho and Huntress to find Blockbuster who has escaped to somewhere in South America and is developing a zombie virus that can turn anyone into a hulking monster; expanding on his plot in Seeley's run, and we find that Raptor is working with Blockbuster but actually is a double agent working with Batman Inc, though he also makes a point to get access to Grayson's spending account and robs it completely, dispersing the funds to charities immediately. Nightwing claims that was his fake account, a decoy, that was money specifically set aside for that move.
Fourth arc: Nightwing, Robin, Red Hood go to Santa Prisca to find Dr. Hurt, whose location is being protected by Bane; they are off-the-books on this one, operating against Batman's wishes, but Nightwing is determined to rescue the Santa Priscan orphaned teenager being courted as Dr. Hurt's own dark "robin." Things go poorly for Nightwing/Robin/Red Hood but they get an unexpected assist by Azrael/Jean-Paul Valley and escape with their lives, thwarting Dr. Hurt and defeating Bane, leaving behind a new operative, the Bat of Santa Prisca.
I mean there's no excuse for it anymore, Dick Grayson as Nightwing has the potential to be an extremely popular character, given all of his exposure through Teen Titans, Teen Titans Go, Young Justice, Titans, the other animated movies, the Arkham games...
Honestly DC has always been a Big Four — Batman and Robin, Superman, Wonder Woman — moreso than a Trinity, i dont care what they say. It's just that the "and Robin" has been under assault for decades as creators have recontextualized Batman as a dark loner and didn't know how to properly do Robin correctly... something that is still being done incorrectly. But there's been enough things that have gotten Robin / Nightwing exactly right that there's now a deep enough well to really build up his mythos.
