Looks like we are finally getting a promising arc. No more nonsense stories of minor characters' daily lives. Even though it's still a bit early to say but nevertheless the basis of this arc seems to be some sort of an amalgam of the AIM fields and mass control stuff we have seen before. Unless that all was nothing but distraction stories invented by the no doubt wicked antiskill woman, whose smile right before the credits was nothing but suspicious. But who knows.
I hope this arc lasts till the end of the series, sparing us from more rubbish episodes.
