Duke. Madam, I am most apt to embrace your offer.

[To Viola] Your master quits you; and for your service done him,

So much against the [mettle] of your sex,

So far beneath your soft and tender breeding,

And since you call'd me master for so long,

Here is my hand: you shall from this time be

Your master's [mistress].

Oli. A sister! you are she.

[Re-enter Fabian, with Malvolio.]

Duke. Is this the madman?
