Checking again the episode for its production value, I must say that aside of the details dropping on the average level, something was more disturbing than Rin and Cecilia Yandere mode: Do Ichika and Charlotte play musical chair with their hands?
I mean, in all honesty, Ichika picks Charlotte right hand with his left (logical for the moment), then the stalkers see them holding... each other right hand, and as the "couple" arrives, they are back to Left - Right.
Errr...?
