AND THIS IS ALSO PERFECT. Ami being the one to believe in Chibiusa. Because Ami and Chibiusa are really similar in a lot of ways- they’re both precocious girls who were ostracized by their peers, who felt alone and timid, who felt neglected by their parents, who wanted desperately to follow in their mothers footsteps and wondered if they could live up to the high standard that their mothers embodied
AMI AND CHIBIUSA ARE REALLY FREAKING SIMILAR AND I NEVER NOTICED IT UNTIL THIS MUSICAL POINTED OUT THE PARALLEL! That is amazing writing,
So of course Ami recognizes Chibiusa’s pain. And since Usagi loved Ami and accepted her, Ami wants to be that person for Chibiusa. She’s not going to be suspicious of Chibiusa like her peers were suspicious of her. She wants to believe in her, because she knows that’s what she needed herself.
