Joe Ga was very pleased with Dvali's offer, and the timing for the second payment was very well-considered...
'Year-end'!
This means that Shah's purge will conclude by year-end, and only then can the Crown Prince free up such a significant amount of funds.
No one doubts Shah's financial prowess; the only issue that can hinder Prince Salman is that he alone does not make all the decisions.
The internal problems must be resolved before he can freely utilize Shah's wealth.
Dvali gave such a pointed hint, waiting for Boss Joe to ask further so he could bring up some additional requests.
For example, having P.B. send someone to do some dirty work for Shah...
Boss Joe wouldn't fall for something like that; Shah's internal affairs are a mess.
The princes who might be purged themselves are inconsequential; a life is a life, but the network of relationships behind them is too complex.
