What If Tomoko And Suzie Q Roleswapped?
I am surprised no one thought of what if Tomoko was Joseph long married wife while Suzie Q was the college student affair he had. Their backgrounds would change a bit to make things make sense in this AU. For instance, Tomoko would meet Joseph earlier in New York (and she would be a Japanese immigrant to America) where he would come across her and Smokey at the same time. They hit it off and become friends and companions which evolves into something more. She wouldn't become a hamon user but she sticks by Joseph side to the point she travels to Italy with him and would like Susie Q in canon nurse him back to health. I still would keep it in she still forgets the send the telegram saying he was still alive. Due to her being Japanese ,if she went back together with Joseph when the war happened then she would be in an internment camp which actually would influence Joseph to have less anti-Japanese feelings especially for his wife and son's sake. For Josuke, he would be born the same spot that Holly was in canon. Like Holly, when he grows up he would move back to Japan to be in touch with his mother's roots which would sadden Joseph a bit but he wouldn't declare hatred for the Japanese unlike in canon. Josuke could have a child who is a girl or a boy but he could himself join his father as a Stardust Crusader if his child is not game enough to fight off the parasitic stand.
So this is where AU Suzie Q comes in this, she would be the caretaker of the aging Lisa Lisa and probably would be seen with Joseph on his visits. She like Tomoko in canon would be a college student taking up a job to pay a tuition and I could totally see her being smitten when Joseph visits his mother and they have a bit of an affair and in this case Holly is born. And if Lisa Lisa lives long enough to notice her maid got pregnant then eventually birthed a child that had the star mark then she would so be pissed at her son for not only cheating but also leaving her to raise a child alone. And we can still have a part 4 but it takes place in Italy where it would be all about Holly and she would have a stand but would have more battle spirit to control it. I do think Josuke or Josuke’s kids would go in Jotato’s place to inform Holly and Suzie Q about their status in the Joestar will.
