I like how Usagi didn’t stop crying because Mamoru inspired or moved her or anything, she was just looking around like “where the hell did that voice come from? what?”
Then Luna has a chance to come in and give actual useful advice she can follow.
Her little smile when the tiara comes off is so cute. She was panicking without a way to fight back, but now she has one and she’s like “this is pretty neat aw yeah I can do this”.
