I'm just wondering if Josuke got his fever around the time that Dio first got his stand(A year before SC starts/ 1987), when SC began or after they defeated Dio. I think it would make the most sense if it was during SC because it's stated that the fever lasted for 50 days and the journey lasted for 50 days as well, but I'm unsure. I'm unsure because Josuke was 4 when he got the fever, yet SC first started in 1988, that was 11 years before DiU, so does that mean Josuke is 15? But yet again, he was born in 1983, so he should be 16, right? I might've just wasted my time because he could be 15 turning 16, but could someone give me a proper explanation, bcoz I don't trust myself. BTW sorry if I don't make sense or I seem dumb, I only got 5 hrs of sleep.
