Act 2, Scene 2, Paragraph 795

Go, then; find me a meet hour to draw Don Pedro and
the Count Claudio alone: tell them that you know
that Hero loves me; intend a kind of zeal both to the
prince and Claudio, as,–in love of your brother’s
honour, who hath made this match, and his friend’s
reputation, who is thus like to be cozened with the
semblance of a maid,–that you have discovered
thus. They will scarcely believe this without trial:
offer them instances; which shall bear no less
likelihood than to see me at her chamber-window,
hear me call Margaret Hero, hear Margaret term me
Claudio; and bring them to see this the very night
before the intended wedding,–for in the meantime I
will so fashion the matter that Hero shall be
absent,–and there shall appear such seeming truth
of Hero’s disloyalty that jealousy shall be called
assurance and all the preparation overthrown.
