Feste was Olivia’s father’s jester, and is now hers, though it appears that he wanders around a bit.
An excellent singer, he also plays the pipe and tabor. He is not especially tall, nor especially thin. An expert in wordplay, he attempts to bring Olivia out of her melancholy and mourning, though this brings him Malvolio’s scorn. His wordplay is also useful in convincing people to give him money. Though he joins in the plot against Malvolio, it is clear that his first loyalty is to Olivia: he runs to find her when Sir Toby and Sir Andrew set upon Cesario, and refuses to let Fabian read the letter the steward sends Olivia from his prison, apparently thinking the prank has gone long enough. When Malvolio is freed, however, Feste does make certain to remind him of the scorn he has poured on his underlings. He appears to be the only member of Olivia’s household who thinks she should be cheered up. As he was her father’s jester, it is likely that he has known her all her life.
