One thing I’ve noticed is that Pearl doesn’t do the over-the-top ballerina motions anymore. Or if she does, its not as much.
Pearl used to do these ballerina motions all the time. She even had her robot in Back To The Barn do the ballerina motions. In fact, unless I’m remembering wrong, the last time we see her do the ballerina motions is in Mr. Greg
A song where she sings about moving on. I think that’s pretty poignant. Especially since we see some hints that the ballerina thing is not exclusive to our Pearl, but it seems to be a Pearl thing. Yellow Pearl especially has the same over-the-top mannerisms that Pearl used to do.
So it seems the ballerina thing is shown less and less because of how Pearl has grown as a character. Where she used to be ruled by her role as a Pearl, she has grown so much as an individual.
