My lord High Overseer,
I've done as you asked and applied the "special alchemical agent" to the glass on the left. It's tasteless and without odor, and will be quite effective. To be clear, your glass is on the right.
I must admit, my hands trembled mixing and pouring this offensive concoction. But I understand that you know things I do not, and therefore I will not question the wisdom of your decisions.
Yours in the Strictures.
