Is a sub story ever finished? I see we are into a new story, the previous one is left hanging as usual. Maybe this is a soap opera?
When authors go all ADD on us like this, I generally tend to give them the benefit of the doubt, usually all these sub-plots come together into a coherent whole, and the skipping around is to keep them fresh in the reader's mind when the big reveal is done. That said,
another thread to follow, this late in the current arc, leads me to believe that they might be trying out a new way of interleaving the story arcs. We'll see.
And yes, sub-stories are finished, I'd say Neann's rescue is pretty much over.
