Just because it's been a long time doesn't mean that he's absolved of guilt and, what's more, that the writers/editors let it happen. Other characters still get shit all the time for the things they've done in relationships even longer than when this happened; Dick's not absolved just because he's Nightwing.
I think I misspoke. I was saying that editorial should be more inclined toward Dick/Kori because of all of the outside influence, not that they were.
Thank the Dark Lord.
I don't actually see it ending yet. I think that instead of ending it, they're more inclined to keep it running through to 5G with Robbie Thompson at the helm - after all he's JUST joined for this next arc.
