the friendship between Dio and Jonathan, after watching the anime, did exist to a point IMO. When Jonathan died holding onto Dio's head, You can clearly hear that Dio was shaken ("Jojo...? He... Is dead..." you just gotta love Takehito Koyatsu's fervent performance): His tone changed from arrogant, stark-raving maniac to somewhat subdued and low tone the way Dio talked to Jonathan in friendly facade. Even though Dio murdered many men with his own hands including his fathers (both biological and adopted), and bragged throughout the arc that he can and will kill Jonathan without regret - only to be surprised and shaken when Jonathan really did die... I thought, the friendship/relationship between the two is truly bizarre indeed.

that being said, I say yes for Jonathan.
