for his son. When they hear that the Mikado's son "goes by the name of Nanki-Poo", the three panic, and Ko-Ko says that Nanki-Poo "has gone abroad". Meanwhile, Katisha is reading the death certificate and notes with horror that the person executed was Nanki-Poo. The Mikado, though expressing understanding and sympathy ("See How the Fates"), discusses with Katisha the statutory punishment "for compassing the death of the heir apparent" to the Imperial throne – something lingering, "with boiling oil ... or melted lead". With the three conspirators facing painful execution, Ko-Ko pleads with Nanki-Poo to reveal himself to his father. Nanki-Poo fears that Katisha will demand his execution if she finds he is alive, but he suggests that if Katisha could be persuaded to marry Ko-Ko, then Nanki-Poo could safely "come to life again", as Katisha would have no claim on him ("The flowers that bloom in the spring"). Though Katisha is "something appalling", Ko-Ko has no choice: it is marriage to Katisha or painful death for himself, Pitti-Sing and Pooh-Bah. Ko-Ko finds Katisha mourning her loss ("Alone, and yet alive") and throws himself on her mercy. He begs for her hand in marriage, saying that he has long harboured a passion for her. Katisha initially rebuffs him, but is soon moved by his story of a bird who died of heartbreak ("Tit-willow"). She agrees ("There is beauty in the bellow of the blast") and, once the ceremony is performed (by Pooh-Bah, the Registrar), she begs for the Mikado's mercy for him and his accomplices. Nanki-Poo and Yum-Yum then reappear, sparking Katisha's fury. The Mikado is astonished that Nanki-Poo is alive, as the account of his execution had been given with such "affecting particulars". Ko-Ko explains that when a royal command for an execution is given, the victim is, legally speaking, as good as dead, "and if he is dead, why not say so?" The Mikado deems that "Nothing could possibly be more satisfactory", and everyone in Titipu celebrates ("For he's gone and married Yum-Yum").
