Malvolio is introduced as Olivia's arrogant servant who believes himself superior to the other servants, particularly Feste. Malvolio is also portrayed as a puritan since he disapproves of the others' late-night celebrations involving drinking. The document then provides quotes that characterize Malvolio and establish the plot - he finds and believes a forged letter implying Olivia loves him, and follows its instructions, only to be humiliated and imprisoned as part of a trick played on him by some of the other characters.
