About Mercury: I hate watching Usagi acting that way. But at the same time I pity her. So much is happening and she has no time to process it. I hate Ami for slapping her but I understand the meaning for it. It’s a very intense scene. Sailor Jupiter sacrificed herself and Sailor Moon was willing to give up the Legendary Silver Crystal, then she starts acting hysterical until Sailor Mercury slaps her to calm down Sailor Moon. Mercury did apologies however.
