Lucentio (no longer disguised as Cambio) and Bianca head to the church to be married while her father is busy making arrangements with Tranio and the Pedant. Petruchio, Kate, Vincentio, and Grumio arrive in Padua and stop at Lucentio's house. Vincentio insists his companions join him for a drink, but upon knocking at the door and announcing himself, he is surprised to find another man who claims to be Lucentio's father. When Biondello appears, Vincentio questions him. Biondello pretends not to recognize his master's father. When Tranio comes to investigate the commotion, he too pretends not to know Vincentio. When the Pedant defends Tranio, claiming he's Lucentio, Vincentio moans that Tranio must have murdered the real Lucentio and assumed his persona. Baptista, unwilling to put up with such wild behavior, orders Vincentio to prison. At this point the newlyweds, Lucentio and Bianca, return.
Lucentio explains what has happened, why Tranio was masquerading as his master, and announces his marriage to Bianca. Baptista and Vincentio reconcile minimally and enter the house to untangle the situation in which they find themselves. Gremio, realizing he has no hope for a spouse, goes inside to join the wedding feast. Petruchio asks Kate for a kiss, and when she refuses, he threatens to return home again. Good humoredly, she kisses her husband before heading in to the feast.
