Dr. Young prepares a medicine decoction and stresses brewing requires precise heat — not too strong, not too weak. He suggests using a professional decoction service, prompting the recipient to ask, "So I'll have to come get my medicine from you every day?" Dr. Young replies he can bring it when he's free. While handing the cup he warns, "Careful, it's hot." An earlier offhand suggestion lands oddly, and the recipient presses him: "Dr. Young, what do you mean by that?" The question hangs unresolved.
