WARNING: The following contains major spoilers for Batman: Wayne Family Adventures #7, available now on Webtoon.
After fighting crime night after night for years, the Bat-Family are no strangers to close encounters with death, so much so that dying and coming back to life is part of their "vigilante bingo," a disconcerting game they use to track their achievements. But the newest Batman: Wayne Family Adventures reveals that even Nightwing can't decide if his apparent death in the New 52 counts towards his bingo.
In Batman: Wayne Family Adventures #7 "Vigilante Bingo" by Starbite, CRC Payne, Maria Li, Lan Ma, CM Cameron, and Kielamel Sibal revealed that Nightwing doesn't know if he can claim one nightmarish win that his siblings can easily claim for themselves. The Webtoon begins with the Bat-Family assembled in the Batcave after being called there by Red Robin to celebrate a big milestone in Signal's vigilante bingo -- sending a supervillain to Arkham Asylum by himself. The team congratulated Duke on his achievement, only for him to ask them what else they celebrated. Robin held his hand up and quizzed his siblings on how many of them had started their own superhero team. Afterward, Red Robin asked how many of them changed their names before and most of them held their hands up. Orphan asked how many of them were trained by assassins. Red Hood, hoping to one-up his siblings, asked how many of them had been murdered and brought back to life. Orphan, Red Hood and Robin raised their hands.
Meanwhile, Nightwing questioned if his "thing with the Crime Syndicate" counted or not, stating that he could never remember. Red Hood hurriedly declared that it did not count, while Red Robin said that it did count.
Signal, understandably worried about how many of his new siblings had died and come back, asked if they were being serious. Red Hood shot back that it happened more than he would think. Steering the conversation to a more positive side, Nightwing responded that there were fun parts of vigilante bingo, and Red Robin shifted the group to talking about pranking Batman while they were in the field.
However, Nightwing questioning if his New 52 "death" actually counts is relatively reasonable, considering the strange circumstances surrounding it and the fact that he was only "dead" for a few seconds. During Geoff Johns and David Finch's crossover Forever Evil, the Crime Syndicate from Earth-3 came to Earth-0 in aftermath of the Trinity War event. Hoping to take over the universe, the Crime Syndicate methodically defeated their Justice League counterparts. As part of their plan, Superwoman and Owlman kidnapped Nightwing then revealed his real identity of Dick Grayson on live television. Afterwards, they strapped him to a Murder Machine, a bomb set to explode unless Nightwing's heart stops. Lex Luthor, who had recently turned away from a life of crime, secretly gave Nightwing a pill that stopped his heart for a few seconds.
As Nightwing died, Batman, Luthor and their allies defeated what remained of the Crime Syndicate without the threat of an exploding bomb over their heads. While Luthor managed to revive Nightwing quick enough so he didn't officially die, the rest of the world thought he was dead. Nightwing used his newly gained anonymity to infiltrate the secret spy organization Spyral in the fan-favorite series Grayson.
Given that Red Hood's gruesome death was one of the most important moments in the DC Universe for a very long time, it's only natural that he wouldn't count Dick's heart-stopping for a few seconds as a real "death." Meanwhile, as one of the few who's never died, Red Robin thinking it counts isn't strange. Since Nightwing is the oldest member of his siblings, he naturally has a lot more experience than the rest of the team, but dying and coming back is one of the few experiences that his juniors seem to have over him.
