I’m not going to defend Rose, because I do agree that she had more power as a diamond than as a quartz. I do think it fits her position of privilege that she didn’t fully grasp that. It works from a character POV for sure.
But I keep seeing people saying that her fake death instigated a war and just... ???? I got the distinct impression the war had began before Pink Diamond was ‘shattered.’ It’s clear it made things worse after it happened, but it’s not what started the war.
I 100% believe Rose Quartz, for a while, was a disguise PD donned to explore earth and get to know her gems on a personal level before the war started, and that moonlighting as Rose is how the war began. While off being the whole princess in disguise, she began to see the difficulties of her people, started talking to them, learned about them, asked them why they couldn’t live differently, and in turn, she began giving them ideas and/or fueling certain ideas, and when they asked her if it possible to live better, she encouraged them, led them even, away from their posts and to push against their roles.
I can’t place why, but I also got this sense, walking out of that episode, that this wasn’t the first time Pearl took on the guise of Rose Quartz. The way she’s posed so often with her eyes shut, when Pearl’s eyes were the give away to the audience that it wasn’t Rose we were looking at, gave me the distinct impression that until PD was ‘shattered,’ if Rose needed to be in two places at once, Pearl would go in her place as RQ.
And that in itself may have had a lot to do with her decision to fake the PD death. I don’t know that I’d say I think it was a wise thing to do, but realizing they couldn’t have both Rose Quartz and Pink Diamond, she may have decided it would discourage and even ruin the rebellion for them to realize their general was Pink Diamond. The purpose of the rebellion was to break away from Homeworld society, and if it just became a Diamond versus Diamond, they’re still all just falling into place behind a Diamond. It was important that the leader was a Quartz, was someone who wasn’t supposed to be the Leader.
And we got to see in the episode beforehand that she did plea with the other Diamonds to be left to do what she wanted to with earth. They ignored her. I don’t think she had this passion before she explored the earth, and I think she only freely explored earth after she’d run around as RQ.
Her fake death certainly raised the stakes. But I don’t think it instigated the war. The war had already begun; the other Diamonds just finally took it seriously when they lost PD.
Also, I will generally refer to PD as Rose given that’s the name she chose for herself. It’s pedantic, but I’m a big believer in chosen names, and she quite deliberately left the life of PD behind.
