He promises to deliver La Valliere back to the arms of Raoul.
In two months' time, Philippe promises that Aramis will be made a cardinal.
He asks for Aramis's other ambitions.
Aramis argues that Cardinal Richelieu's greatest mistake was allowing two kings of France – Richelieu and Louis – to try to rule as one. It's much better to have two separate thrones.
Aramis says to Philippe: "I shall have given you the throne of France, you will confer on me the throne of St. Peter." In other words, Aramis wants to become pope. He is convinced that Philippe can rule the bodies of men and Aramis will take their souls.
