I think whoever was behind the assassination did it do get a more hotheaded individual in place. There are more cards to be played yet.
I agree. I don't think that individual is Ishan, though. The puppetmasters, whoever they may be, probably arranged for Ishan to be the pro tem, but I don't think Ishan is their puppet. I think whoever comes after him is the real goal. The person elected to replace Bacco is the ultimate goal.
