What's the meaning of the last line of this extract from Shakespeare's Two Gentlemen of Verona?
Valentine. This is the gentleman I told your ladyship
Had come along with me, but that his mistress
Did hold his eyes lock'd in her crystal looks.Silvia. Belike that now she hath enfranchised them
Upon some other pawn for fealty.Valentine. Nay, sure, I think she holds them prisoners still.
Silvia. Nay, then he should be blind; and, being blind
How could he see his way to seek out you?Valentine. Why, lady, Love hath twenty pair of eyes.
Thurio. They say that Love hath not an eye at all.
Valentine. To see such lovers, Thurio, as yourself:
Upon a homely object Love can wink.
