Some thoughts on Rainbow Quartz
So I was thinking of why Pearl and Rose would "fuse... a lot" and there is the obvious answer that Gems who love one another just like to fuse and be close (duh). That is a given.
But I also think it was special for Pearl and Rose because of what it allowed them to feel.
We know Rose did not like herself. As PInk she saw herself as not mattering to the Diamonds while also being too high up to connect with anyone Else. She was told hundreds of times that she messed things up and made things worse and she internalized It.
We also know Pearl saw herself as pretty worthless on her own. That her only value could come from what she could provide to someone more important than herself.
We also know they could not get the other one to fully abandon that view of themselves. That Pearl and Rose argued about this during the war.
But as Rainbow Quartz, I think they could get the other to see/feel themselves the way they saw them.
Rose saw Pearl as brilliant and full of potential to do anything she set her mind to. Pearl saw Rose as this incredible kind and caring person that brought out the best in herself and others. As as Rainbow they could feel that way about themselves
If you had asked Rose or Pearl alone they probably would have given the other full credit for how far the rebellion got and none to themselves. But as Rainbow they could acknowledge they worked together.
A big point the show makes is that a relationship cannot fix you and nobody's love can force you to love yourself. But someone respecting and loving you obviously helps, and I think Rainbow allowed them to feel respected and loved in a way they never had before her.
Plus, she is a giant hot dancer. Who does not want to be a giant hot dancer?
