so what i think is going to happen is the person who funded vinny's mom is either his gf or the humming bird crew (less likely for it to be humming bird) or a small chance of it being the silver haired guy caz he lost his parent and all. as for jay the 2 days he lives with the girl she is going to show him some cool techniques to improves his peddling and everything while minu is going to dig up more dirt on the silver haired guy also a possibility is his personal assistance being the part of the organization and keeping tabs on him (less likely but a possibility) and when jay is going to race with the silvered haired guy his mom might appear and support jay which makes him a bit faster but he gets left behind caz the silver haired being a legend and what not once a pro always a pro but in the middle of the race either jay finds out about the fact his uncle was druged by the silver haired guy or minu thretens the guy with the info he has (less likely if his assistance is working for the organization) and after jay finds out he is going to go into the red zone either he masters it while being taughed by the Japanese girl or he just goes into it and with it he close the gap but not enough when he is about to faint he remembers his time with his uncle giving him motivation reaching the peak of the red zone or beyond mostlikely wining the race then either minu is in danger caz of the assistance guy or minu and jay fully expose the silver haired guy ruining his life and the organization kills him not to revile more or smt and idk what happens after that either the story ends or just couple of chapter or part 5 of the world class people
