Nightwing defeated the villain and literally sent him running. Those scenes are actually important, as they demonstrate that Blockbuster didn’t just lose the fight. He has also lost his hold on the the people of Bludhaven and his influence over his organization. This was the end for Blockbuster. They aren’t looking to do more with Blockbuster. I think they made that rather clear. So yes, congratulations Nightwing. Now he and Bludhaven can move on.
