go my army of wicked evil ducks

Silver clearly looked up to his father, who is in crisis due to his failure and the defeat of his organization, and he's saying he needs to figure out how to get stronger and put the pieces back together. And his son literally berates him and calls him weak.

Giovanni is not even rough with him, he tells him he'll understand one day, and Silver literally runs off screaming and crying that he'll get stronger all by himself.

I think it's just as easy to read this as Silver running away as much as it is to read it as Giovanni abandoning him. We don't have any of the context surrounding the event. We don't know if Giovanni brought Silver there to ask him to go with him, we don't know if Giovanni was planning to leave before Silver's outburst. We don't know what happened afterward.

All we get canonically is the snapshot of how their relationship dissolved. Silver looked up to his father and put him on a pedestal, and that idolization was destroyed and Silver became bitter toward his father.

My personal headcanon is that Giovanni was either planning to bring Silver with him when he left, or to tell him he was leaving for a while and put him in the care of his mother. But Silver freaked out and ran away after that/soon after that.
