POLONIUS My lord, do as you please,
But if you hold it fit after the play
Let his Queen-mother all alone entreat him
To show his grief. Let her be round with him
And I’ll be placed, so please you, in the ear
Of all their conference. If she find him not,
To England send him or confine him where
Your wisdom best shall think.
CLAUDIUS It shall be so.
Madness in great ones must not unwatched go. (Exeunt.) (3.1.179-187)
The last moment of this extraordinary scene sets up a major plot point to come, as Polonius tries both to help and to retain some agency in events as Claudius’s right-hand man (Ophelia apparently not figuring in his thinking). My lord, do as you please—of course, it’s absolutely up to you—but if you hold it fit after the play let his Queen-mother all alone entreat him to show his grief. Polonius still thinks there’s more to this, whether it’s about Hamlet’s relationship with Ophelia or not, and now he wants to co-opt Gertrude (just as he has Ophelia) into making Hamlet speak more freely about his state of mind. Let her be round with him—tell her to put him on the spot, speak her mind—and I’ll be placed, so please you, in the ear of all their conference. I’ll be listening: surveillance, spying, that’s what Polonius is most confident in, and ideally undertaken by himself, no outsourcing to amateurs like Rosencrantz and Guildenstern. If she find him not—if his mother can’t get any more information or insight out of Hamlet—to England send him or confine him where your wisdom best shall think; then you can revert to plan A, send him on that mission to England, get him out of the way. Or lock him up, that’s always an option. Up to you. Your Majesty. It shall be so. Claudius makes this concession, he needs to keep Polonius on side, and what have they got to lose, it won’t delay things much. And, after all, madness in great ones must not unwatched go. Makes sense to keep eyes on Hamlet as much as possible. I think we’re done here.
Exit Polonius, Claudius—and Ophelia—does Polonius finally go to her, put an arm around her, lead her off with some looks of concern, even apology? Or do the two men just leave her alone, collateral damage, to make her own way? A key choice for a production.
