Narratively it would be worse to build him up and then NOT mention him at key moments. If he were to "stop now", you'd end up with a complete clusterbollocks like Countdown, where character relations consistency between issues was a moot point.
So... it's better for Beechen to stick by his Cass characterization and write a whole mini to further entrench it than to realize that that first storyarc was a mistake and alter his portrayal? It's better for Gail to stay with the "Diana's a directionless moron" characterization from the Heinboot than to write her well? It's better for Bedard to say "Shado is Connor's mother, I wrote it now I'm going to stick with it" and make a point of that in further issues? It's better for Tomasi to keep Dick useless, fail-y and weak in order to have issue-to-issue consistency with RIP and prior runs of NIGHTWING?
