She seems overcome with surprise, and is confounded.
After CARLOS' departure she hastens to call him back.

PRINCESS.
Prince, but one word! Prince, hear me. He is gone.
And this, too, I am doomed to bear--his scorn!
And I am left in lonely wretchedness,
Rejected and despised!
[Sinks down upon a chair. After a pause
And yet not so;
I'm but displaced--supplanted by some wanton.
He loves! of that no longer doubt is left;
He has himself confessed it--but my rival--
Who can she be? Happy, thrice happy one!
This much stands clear: he loves where he should not.
He dreads discovery, and from the king
He hides his guilty passion! Why from him
Who would so gladly hail it? Or, is it not
The father that he dreads so in the parent?
When the king's wanton purpose was disclosed,
His features glowed with triumph, boundless joy
Flashed in his eyes, his rigid virtue fled;
Why was it mute in such a cause as this?
Why should he triumph? What hath he to gain
If Philip to his queen----

[She stops suddenly, as if struck by a thought, then
drawing hastily from her bosom the ribbon which she had
taken from CARLOS, she seems to recognize it.
