Totally. But after the last events, unless something real crazy happens, her development cycle is pretty much over with. She stood at Naruto's side, held his hand just like she mentioned and even got a reason to start being more responsible and productive for her clan, though I doubt it might happen given her lack of a decent purpose in life. However if you look closely, every secondary character is finishing their development cycle during these war events. Plus, just like every other story, after the less characters roles are done with, what normally happens first, we'll have the resolution of the main characters drama probably taking place during the final battle between the two protagonists.
That's true. I guess even though they took time away, it at least accomplish that. It's just maybe if it wasn't thrown in many times like past 3 volumes, with some exception like Shikamaru with Naruto, I think it wouldn't be that bad. Still, I think the problem with this chapter, even though it's best to wait and there's still Madara, is that the "final" attack if that is one, doesn't feel that impacted. I don't know, I feel it was more impact with 634.
