Once he's back, I'd like to see Nightwing to have more of a Crisis Management situation. I'm reminded of a part of Spider-Man: Learning to Crawl; that the quips and banter are supposed to cut the tension of the situation, but he could be play both the word-play part and the serious negotiator part. I'd also like to see Rose Wilson show up from time to time (though I don't know if he's still a mentor figure of hers now).
