Oooh, do tell me any angsty thoughts you have about Pearl!Steven. I, however, submit for your consideration, the following: Steven unlocking Pearl's powers for the first time when sooooo excitedly telling Rose all about the latest Crying Breakfast Friends episode and he gets so into that he just starts... projecting it from his gem. It's a very bittersweet moment for Rose.
1) that submission is hereby cancelled bc it made me sad. Absolutely brilliant, I love it so much. The pride and heartache that Rose would feel in that moment would probably be nearly overwhelming. They MADE THIS CHILD, her and Greg and Pearl. And he’s so like her, she’s always seeing little flashes of Pearl in him and Garnet assures her it’s no more frequent than his similarities to Greg or Rose herself, but all Rose can ever seem to see is PearlPearlPearl and she’s full of love and amazement at Steven and who he is and how he exists and what he can do, but she misses Pearl so much it feels like her gem has a flaw in it that will never go away.
2) as for other thoughts, it’s thus far a pretty nebulous AU in my head right now, more vague emotion than any actual concrete thoughts, but something I thought of in the car earlier is that Pearl probably convinced Rose to do it by researching human childrearing practices to try to find a reason Rose couldn’t be the one to do this, and she got into child psychology a bit, and ended up coming to Rose with stuff about the possible effects of the loss of a parent can have on human children, even if they can’t remember the parent or never knew them.
and really, in the end, Pearl’s always sacrificed herself for the love of Rose. It’s part of her programming, so to speak, but even having pushed past that, Rose opened the world for Pearl. She treated Pearl like a person, like an EQUAL. Listened to her, encouraged her, laughed with her. And so she set her own mission. For the love of Rose, she will go to every length to protect her, even from herself. She would, if she had to, look at herself in the mirror and, to steal something from an amazing bit of Sailor Moon commentfic @seananmcguire once wrote, say “for the love of Rose, burn.” And she would.
Even if it breaks Rose’s heart, she’s never found a way to stop Pearl yet. It seems inevitable, afterwards, that it would turn out this way in the end.
