One thing that really stood out for me is how supportive Ushiyama is of Tsubasa. Must've been hard on Tsubasa to have Mariko be succeeded not only in her lifetime, but during her time as lead organizer. So yeah, I was actually pretty touched when Ushiyama encouraged Tsubasa that Mimori still has nothing on her.
Which makes me wonder, exactly how long has Ushiyama been with AKB0048 organization to be there since at least Tsubasa's succession? Like, how did he even know about Tsubasa's fever, when its just the understudies in the dorm? Was he actually an understudy despite being male? I so wanna know, and for once I wish there was some prequel that details this time.
But yeah, congrats on succession Mimori. Though Ms. Photographer being the mole really put a downer to things, as I have taken a liking to Tsubasa, and her being the traitor makes it worse since Tsubasa was the one who have hired her.
