Third Nightmare

I'm pretty much stacking since the third nightmare ended, since I was hoping the whole 'memory-loss' was going to be a one-arc thing rather than... whatever it is now.

Is it anywhere close to getting there? Or even hinted at, or trying to find the solution? I know people said the story is very good anyway, but it doesn't really feel like anything I read before the third nightmare matters anymore since it's all wiped clean relationship-wise.
