Aye, sir! I had no doubt you would return, rex quondam, rexque futurus! Your return is reward aplenty. May the banner fly in perpetuity!
Glorious leader! I will faithfully wield your banner until your return. You are the once and future king.
Happy Birthday, good sir! For a pseudo-present, rest assured that I continue to boldly proclaim that your dynasty is no laughing matter...in vague hopes that I will be appointed Prime Minister when your plan comes full circle.
