Maria

She a gentlewoman in Olivia's household, and protects her from fools like Sir Andrew. In fact, recently she set up Malvolio to kick him down a
peg or two. She was and still is a faithful servant,
as she was the one to help keep Oliva's face
hidden from Cesario for as long as possible. In hindsight, she just wishes the best for her majesty.
"I will drop in his way some obscure epistles of
love ... I can write very like my lady your niece."
