Guys, look very, very closely at this image
>Gaju and Mako in symmetrical pose as a dancing pair
>Tatara and Chinatsu not symmetrical
>Tatara symmetrical with Shizuku instead.
Notice who Chinatsu is symmetrical with? Surprise surprise....it's Hyodou.
Is this a teaser for the next arc perhaps? Chinatsu breaking up with Tatara and pairing with Hyodou who is a better leader and who is more on her skill level?
Possible hint #2
Hyoudou dragging and pulling over Chinatsu flawlessly in spite of her protests.
Possible hint#3
Chinatsu having no problems at all dancing with Hyoudou in spite of her lack of experience following.
