Maybe ambassadors get paid by the foreign powers they serve? Like – he travels to places delivering the news of favors performed by his government and the kings of those places nod and say “Thanks so much” and hand over a sack of money. Maybe that’s why this English ambassador is behaving so insensitively – because he’s worried he won’t get paid now that the king is dead. He’s wondering where to get his thanks because he’s wondering how he’s going to feed his kids.
Maybe. Probably not. That would be a super weird way to do it.
