Inspired by the poll where listed why I would marry prospero in kiss, marry, kill, I created an oc who marries him for the exact reasons listed!!! This is one of my rare fan ocs that I don't think fit slyly into cannon even a little bit!
She and Prospero met in public school as children (I'm fairly certain the education for everyone act had been passed. It's why Laura Ignalls was going to school in "On The Banks of Plum Creek")
They remained friends and she tended to but into his studies as women weren't really accepted in college at the time. However, she had different interests then him. (She wanted to study the natural sciences).
They stayed in touch over letters, and in person Prospero admired her ability to use how society saw her to get what she wanted out of any given situation. She was also incredibly passionate about the sciences and learning. Plus, she was rather clever, didn't give up (stubborn to a fault, tho that is a very much a flaw in Prospero's mind, tho he likes her determination), and good at coming up with jokes on the fly.
Rose liked that Prospero treated her as an equal, understood why she sometimes "just couldn't" do things (he had the same problem), and accepted her quirks with no more than an eye roll and a sigh. They understood each other well just by virtue of having known each other most of their lives. (Prospero was also always willing to help her with puzzles over mail).
Theirs was a marriage of convenience. Rose was new money, her father having managed to master the stock market. Prospero got a job at Adirondack Cottage Sanitarium. The sanitarium had trouble keeping its doors open due to money cuts, Prospero wanted to help people and needed to support his mother.
The sanotoruim would get some of the family money, Prospero would get social pressure to marry off his back, as well as a partner who would understand him, and take care of things like household chores (wifely duties), giving him time to actually take a break if he wanted it.
Rose got a beard, no pressure to have sex, a husband she could trust, and access to both Prospero and the other doctors medical notes and research. Not to mention the beautiful mountain view, waiting to be catalogued a studied down to the last blade of grass.
Prospero's family didn't like Rose much.
Of course, Prospero dies. Luckily the house was already paid off. Rose's OCD paranoia about contamination gets worse. She barely makes it to the funeral and burns what things Prospero's family doesn't take. Eventually she claws her way out of that hole, and gets back to work.
She's her father's again. And while she loves and trusts him, she wants to be her own.
She gets back with the suffragettes, works through both wars, fights for equal rights, for all. Eventually she sells the house and moves into the big city. Once she gets settled, she works at a factory like she did back during the wars. In the 60s she joins the hippie movement and fights for world peace. All the while, she keeps doing can for those around her small community. The queer youth know they can go to Rose if they're in trouble. In 1967, on her way back home from protesting the Vietnam war, she is hit and killed by a car in what is genuinely a freak accident. She wasn't done yet.
At my brother's insistence, she was in the same class as Lenore's older brother theo. Her relationship with Prospero was only the beginning of her life.
