For the first time in thousands of years you felt you had a purpose, a reason to keep existing. She, the one who murdered your Diamond, was right in front of you with her unmistakable shield, covering the last remains of her army of traitors. Even if she was so weak and seemed so scared and confused, it had to be her.
You went through a lot of shameful failures but nothing stopped you. Nor being slammed into a generator or the months imprisoned in a fusion, certainly not the weird feeling that something was very wrong with Rose Quartz. Her weakness was puzzling and her fusion with that human the most disgusting thing you had ever seen, but it didn't really matter. You couldn't waste time overthinking things. So you put your latest plan in motion.
The pain is unbearable. Your physical form is all over the place and you struggle to keep it right. You know you deserve it, you have commited the lowliest act you could think and all because you weren't strong enough to defeat that fusion of lowlifes. And now she is there pitying you, saying she can heal you. No, no, no.
You may be about to become a mindless monster but that doesn't mean you will become a prey to her manipulations and pretty words. She is even denying she is Rose. Pathetic. You know what she really is and you won't betray the memory of your Diamond to become one of her is all her fault and before you lose your ability to think coherently you will make sure she will know.
"Help..? Help?! I've been fighting from the second I broke free of the Earth's Crust, because of what YOU did to my colony! Because of what YOU did to my planet! Because of what YOU did to my Diamond!"
She looks utterly confused and cautiously says "I…Yellow Diamond?"
Your entire body freeze like you are back in the bottom of the ocean. You are horrified. This must be a trick, other of her lies. She is messing with your head.
"Wha…My Diamond! Your Diamond! PINK DIAMOND!"
You are so distraught you barely note your body keeps changing. This can't be. Even Rose Quartz couldn't feign this absolute ignorance of who Pink Diamond even was. Because she clearly doesn't know, it's written all over her face.
And then you know everything you have done has been for nothing. You can't keep denying it.
That gem…human… that thing is not Rose Quartz.
