I like the point you made her.



Pink definitely was the entertainer, i.e. Blue telling Steven how Pink would swim to the bottom of the pool to sing, and the others would try to guess the song. Yet, unlike Spinel, it was not her purpose.



Pink saw herself as a Diamond and wanted the same treatment, but her childish behavior made it so she came off as the hot-tempered brat.



Then when she got what she wanted, she was let down because it was "so boring!" and she wanted things to be fun again. Sneaking down to Earth with Pearl let her have fun again, but it also matured her. She saw that what her people were doing was harmful to other lifeforms. Her character development was furthered by forming the Crystal Gems, and finally when she met Greg. Still bothersome that she left Spinel behind even after forming the Crystal Gems.
