In chapter 94 of Stone Ocean, Pucci and Dio are seen laying in bed together.
Dio tells Pucci that with his ability he could take his Stand anytime he wanted. He grabs his wrist tightly asking if he'll betray him one day. Pucci refuses to take Dio's stand disk, explaining that he'd never betray him because he wants to see him grow. He also tells him that he loves him as much as he loves God.
Dio states that Pucci is someone he can trust from the bottom of his heart. Pucci's actions in Stone Ocean are to resurrect Dio and finish his goal of achieving heaven.
In the video game Eyes of Heaven, Dio and Pucci hold hands for their Dual Heat Attack animation.
