I just realised that Pearl, during her flashbacks, at least in these, never sees Rose’s face

She’s in love with an idea of Rose that she has. She never considers how Rose may actually be seeing things or how Rose may actually feel. She’s deitised and objectified her.

In Garnet’s eyes, she sees things as simple, but Rose’s feelings are always projected too. With all of Pearl’s vividness in imagery, Rose’s eyes, the window to her expression, are things she didn’t see.
