ACT II. SCENE I. 

By your patience, no. My stars shine darkly over me; the
malignancy of my fate might perhaps distemper yours; therefore I
shall crave of you your leave that I may bear my evils alone. It
were a bad recompense for your love to lay any of them on you.

No, sooth, sir; my determinate voyage is mere
extravagancy. But I perceive in you so excellent a touch of
modesty that you will not extort from me what I am willing to
keep in; therefore it charges me in manners the rather to express
myself. You must know of me then, Antonio, my name is Sebastian,
which I call'd Roderigo; my father was that Sebastian of
Messaline whom I know you have heard of. He left behind him
myself and a sister, both born in an hour; if the heavens had
been pleas'd, would we had so ended! But you, sir, alter'd that;
for some hour before you took me from the breach of the sea was
my sister drown'd.

A lady, sir, though it was said she much resembled me,
was yet of many accounted beautiful; but though I could not with
such estimable wonder overfar believe that, yet thus far I will
boldly publish her: she bore mind that envy could not but call
fair. She is drown'd already, sir, with salt water, though I seem
to drown her remembrance again with more.

O good Antonio, forgive me your trouble.

If you will not undo what you have done- that is, kill
him whom you have recover'd-desire it not. Fare ye well at once;
my bosom is full of kindness, and I am yet so near the manners of
my mother that, upon the least occasion more, mine eyes will tell
tales of me. I am bound to the Count Orsino's court. Farewell.
