What are these fears? What are you dreaming of?

PAULET.
How high soever the queen may pledge herself
To raise you, trust not her alluring words.
[The spirit of the world's a lying spirit,
And vice is a deceitful, treacherous friend.]
She will deny you, if you listen to her;
And, to preserve her own good name, will punish
The bloody deed, which she herself enjoined.

MORTIMER.
The bloody deed!----

PAULET.
Away, dissimulation!--
I know the deed the queen proposed to you.
She hopes that your ambitious youth will prove
More docile than my rigid age. But say,
Have you then pledged your promise, have you?

MORTIMER.
Uncle!

PAULET.
If you have done so, I abandon you,
And lay my curse upon you----

LEICESTER (entering).
Worthy sir!
