_Isaac_. [_Aside_.]So, I find they are all in a story. Egad, I believe
I have gone too far!

_Don Ferd_. Sure, sir, there must be some mistake; it can't be my
sister whom he has seen.

_Don Jer_. 'Sdeath! you are as great a fool as he! What mistake can
there be? Did not I lock up Louisa, and haven't I the key in my own
pocket? and didn't her maid show him into the dressing-room? and yet
you talk of a mistake! No, the Portuguese meant to insult me--and, but
that this roof protects him, old as I am, this sword should do me
justice.

_Isaac_. I[_Aside_.] must get off as well as I can--her fortune is not

_Isaac_.
Believe me, good sir, I ne'er meant to offend;
My mistress I love, and I value my friend
To win her and wed her is still my request,
For better for worse--and I swear I don't jest.

_Don Jer_.
Zounds! you'd best not provoke me, my rage is so high!

_Isaac_.
Hold him fast, I beseech you, his rage is so high!
Good sir, you're too hot, and this place I must fly.
