Bruce as Nightwing.
But what if, and it's possible bc the Batfamily sucks at communication, EVERYONE is suddenly Nightwing.
Nightwing!Jason is in the shadier areas of Bludhaven, beating down would be rapists and drug dealers selling to children. (Is the one people believe is the real Nightwing but they notice the height difference and think it might be shoe inserts)
Nightwing!Tim in a slightly padded suit with shoe inserts swooping around down town Bludhaven.
Nightwing!Damian (obviously not real Nightwing), helping people in the park.
Two female Nightwings, one blonde and one black haired, zipping around on motorcycles patrolling.
Nightwing!Duke obviously still pulling the day shift role.
And then there's ScowlWing aka Batman playing dress-up. Everyone KNOWS this isn't their Nightwing. They think he's someone's uncle who wants to protect Nightwing but might end up getting hurt. People appreciate the sentiment.
