Really? She just suddenly has full control over activating her Byakugan and has learned gentle fist - which either is useless seeing how little effect it had on today's situation (a strike to the heart is supposed to shut down the entire body), or wasn't gentle fist at all, in which case they could at least show us that she learned how to fight, some sort of training session, anything!

I'm not upset at fillers and I'm past the entire "poor writing" stage, that's not what gets to me here. My problem is that they could include all this useless bs in there for the past half a year but couldn't even for a single episode focus on the growth of other characters... They just throw them in our faces being like "oh yeah they can do this now btw." So much good content opportunity wasted...
