Nel reverted to her child form. So i was speculating, might it be Ulquiorra emerging to save ichigo? Would it be Urahara? Or Yourichi?

Little did i expect this guy! I almost swore "holy fuck". We'll see next week, how Zaraki fights Tesla & Nnoitora.
My guess is Zaraki'll either use his brains or reveal a shikai or motivate Ichigo enough for him to pull his mask out once more.
Oh yeah, Kekkaishi manga release seem to have slowed down. The anime i caught is about 2-3 episodes ahead of the manga.
