The tables have now turned and the smug expression of Shylock's is
replaced with confusion, as he says, "is that the law?"
Gratiano echoes the earlier thoughts of Shylock and is now praising
Portia for her judgement. Shylock, knowing that he can't cut off the flesh
without dropping blood, says, "Pay the bond thrice and let the Christian
go." He now wants the money, but as Bassanio goes to hand it over,
Portia tells him that he can't have the money, he can only have his bond.
