The crazy thing about Rena's first iconic "USODA!!" is that it's all from Keiichi's exaggerated perspective. She actually just calmly said "usoda", to an extent, and likely chose to use harsh words on Keiichi because she thought that he would understand her point. At this time, neither Rena nor Mion had any idea of just how far gone Keiichi already was. She never yelled at him or gave him a cold stare. To everyone else, Keiichi was the only one with a crazed look in his eyes. I've known this plot twist for years, but everytime I come back and rewatch the original series, the details just amaze me.
@@baka-oni8358 Rena only yells "usoda" loudly when she's going through the symptoms, which wasn't happening here. it's been confirmed that keiichi was the only one overreacting
