Twelfth Night, or What You Will Act 4, Scene 3 Summary
In Olivia's garden, Sebastian can't believe his good fortune – Olivia, who he has just met, is totally into him and recently gave him a pearl as a token of her love. (Sebastian doesn't know that Olivia thinks he's "Cesario.")
Sebastian wonders aloud where Antonio is – he sure wishes he could find his trusty pal because Antonio might be able to tell him if the rich, gorgeous Olivia is a dream or reality. Sebastian says that if he isn't crazy, it's possible Olivia is.
Olivia enters the garden with a priest in tow. She still thinks Sebastian is "Cesario," who now appears to be in love with her. She tells Sebastian they should get hitched ASAP before her man changes his mind. Best to nail down this whole deal before he runs off with some other woman.
Sebastian thinks this is a terrific idea and says he'll go along with whatever Olivia says.
