thinking about how viola and sebastian's responses to grief are the polar opposites of each other. viola hopes ("perchance he is not drowned"), sebastian despairs ("she is drowned already, sir, with salt water, / though I seem to drown her remembrance again / with more"). viola immediately sets about a plan to make the most of survival and seeks connection with others in grief ("o that i might serve that lady!"), sebastian is set on running away from anyone close for fear of contaminating them with his misfortune ("my stars shine darkly over me. the malignancy of my fate might perhaps distemper yours"). viola wants to live so sebastian can live with her ("i my brother know / yet living in my glass. [...] for him i imitate"), sebastian wants to have followed viola to her grave ("myself and a sister, / both born in an hour. if the heavens had been / pleased, would we had so ended! [...] you will not undo what you have done — / that is, kill him whom you have recovered").
