This question is related to Animal Farm.
At this point in the story, the hens are refusing to give up their eggs, and they are killed by Napoleon's pigs as a result. This leaves the pigs with ownership of their eggs, and they sell them for profit. This signifies that the animals are no longer equal.
 
        
                    
             
        
        
        
I am not completely sure, but this is how I would order these events:
Viola enters Orsino's court dressed as a male.
Olivia asks Cesario about his parentage.
Feste returns the ring to Cesario that Orsino had given to Olivia.
Sebastian reveals to Antonio that he has a twin sister.
Malvolio makes a fool of himself in front of Olivia.
Antonio offers to take Cesario's place in the duel.
