The captain informed Viola that he has seen Sebastian during the shipwreck. The news that Sebastian had fastened himself with a strong mast and he was seen floating over the waves consoled Viola to some extent.
In order to reach the Duke, Viola planned to dress herself in a man's camouflage and to serve him as a page.
