It's my theory is that the cousin is not the cousin afterall but a disguise, in the last panel where it might just show Angelini's family tree, the cousin isn't visible means either he is an illegitimate child or someone else entirely with the perception of taking advantage of the trust he earned.
I'm not sure if it makes sense, I couldn't word my thoughts in a better way so I apologize for that
