Hero pulls Margaret aside in the garden, and gets the wheels turning on her part of Don Pedro’s scheme. Margaret seems to have more importance than what we assume as she is the pivot point of both conflicts of the play : the conflict between Beatrice and Benedick, and the conflict between Don Pedro and Don John. She wants Margaret to lure Beatrice to the 'Garden of Eavesdropping' by saying that Hero and Ursula are talking about her, and Beatrice should listen in on their secret conference. A lot is revealed in this conversation about perhaps Hero's true passive-aggressive character, as she then lights Beatrice’s flaws: calling the girl proud, disdainful, scornful, and too in love with her own wit to love any man. Beatrice comes out at the end of the scene: It’s worth noting that her primary concern isn’t the shocking revelation that Benedick loves her. Instead, she seems really hurt that her friends condemned her for being so proud. Beatrice declares she’ll put her bad attitude behind her, and give herself over to Benedick. Further evidence that this ''relationship'' is not based on true intentions. This then leaves the question that if poems are used to show characters emotional state, then are they true emotions that are being experienced? It could be the method of conformity -the profane idea that everybody should be married in the end.
Claudio volunteers to travel with Don Pedro after the wedding, but Don Pedro points out that Claudio will have more interesting things to do on his wedding night. This joke is very common amongst the ladies as well. Don Pedro says he'd rather have Benedick’s company, because Benedick can be trusted to never fall in love, which is manipulation of his emotions to get a confession. Leonato notes that Benedick looks sadder despite all his changes (haircut, shave and cologne), so either Benedick is in love, or he’s been transformed into a metrosexual. They figure that if any woman loves him, it’s only because she doesn’t know him very well. This brings doubt to the earlier idea that Beatrice and Benedick might have a past together. There’s some taunting about how the girl Benedick loves will die for him, but she’ll die with her face upward. ("Die" is Elizabethan slang for orgasm). This is further evidence for Benedick's promiscuity. Benedick shrugs off all this teasing and asks Leonato to go off with him to talk about serious stuff, which leaves Don Pedro and Claudio conveniently left alone for Don John to prey upon. Don John claims that Don Pedro’s efforts for Claudio’s wedding are all in vain as she is disloyal. Not only is she disloyal, he could call her all sorts of other nasty names, but he doesn’t. Claudio pledges that if he sees anything, he’ll be sure to be as dramatic as possible, by denouncing Hero in front of the whole wedding party tomorrow. Don Pedro pitches in that he’ll help Claudio disgrace Hero at the wedding if there’s proof of her disloyalty tonight. This brings out an unstable and almost sinister side to Don Pedro -considering his responsibility for getting the two together, as well as his final reaction/mood at the end of the play.
There is the introduction of a comic relief in the form of stock characters, these being Dogberry, Verges, and the watchmen. Dogberry tries to pick one among the watch to be the constable, going on to give a series of nonsensical instructions to the watch; essentially gives the men permission to sleep through their shift, but advises that they make sure they aren’t robbed while they’re dozing. More of Dogberry’s ridiculous instructions include: drunken men should be reprimanded, unless they’re too drunk, in which case they should be left alone to sober up. The men on watch should wake up nurses (nannies) whose babies are crying. If the nurses do not wake up at the watch’s calls, the babies’ cries are sure to wake their nurses up eventually. Dogberry goes on in this vein, with Verges throwing in some supportive comments. Whenever they open their mouths, the two men generally reveal that Messina is very lucky to be a quiet town, as their watch is completely incompetent to handle any real crime or disturbance.
Before Dogberry leaves, he tells the men on watch to carefully observe Leonato’s door [yet more coincidence by Shakespeare, considering he wouldn't have the logic to assume a wedding attracts trouble]. Lastly, he tells them to "Be vigitant!" (mistaking the word vigilant?).
The watch’s plan to settle into a peaceful sleep is interrupted by the entrance of Borachio and Conrade, Don John’s two partners-in-crime. Borachio and Conrade haven’t noticed the watchmen, though the watch has noticed them- the act of spectating is key in this play. Borachio updates Conrade on the night’s events, sparing no little detail, and announcing that he’s earned his 1000 ducats from Don John. Conrade wonders how Borachio’s villainous assistance could come with such a high price tag- Borachio points out that when a rich villain needs a poor villain’s help, the poor villain can name any price. Borachio describes how his plan went off without a hitch: Margaret leaned out of Hero’s window and bid him a thousand goodnights (it is safe to presume that more went on before they said goodbye, otherwise Hero's purity would not be in question). Anyway, Borachio replied to Margaret’s goodnights, but he called her "Hero." Why Margaret did not retaliate at this point? It could be a matter of loyalty, as of which it brings out that maybe women were used to being undermined and cheated on with the promiscuity of men.
Meanwhile, Don John was stationed with Don Pedro and Claudio in an orchard, close enough to hear what was going on, but not close enough to see that the woman was Margaret, not Hero. Borachio confirms that Don Pedro and Claudio were fully convinced of Hero’s disloyalty, and didn’t suspect that the scene was a villainous plot masterminded by Don John. Borachio makes the insightful point that the scheme had many layers, like an onion, or a layer cake.Claudio became enraged after "witnessing" Hero’s disloyalty, and he vowed to reveal Hero’s love affair in front the whole congregation tomorrow at their would-be-wedding. He’s determined to send her home without a husband (or her dignity!).
The watchmen, who have been listening this whole time, finally step out and seize Borachio and Conrade, calling them out for lechery (they really mean treachery?), and that they will 'obey them' (oblige them). This shows the stock characters of the play have a heavy case of Spoonerisms.
More of Hero's character is revealed as she gets ready for her wedding and calls Beatrice and Margaret fools. Margaret has no sense of shame or embarrassment as she makes innuendos about the wedding night -her crude and otherwise considered vulgar humour could be proof of how she isn't assumed to be a virgin -and perhaps, likewise with Beatrice. It would explain the dress code and social-ability Beatrice has with ''the common people'', as expressed in the Grand Theatre production. Further evidence as to how Beatrice may not be a virgin (and perhaps why Hero thinks she is better than Beatrice) is as Margaret and her joke about her ''stuffed nose''
*stuffed was a euphemism for pregnancy
*qualm could represent nausea, associated with pregnancy
*benedictus means ''Blessed'' and could further show the word play that Benedict was the father of (and cure to) Beatrice's presumed pregnancy
At the wedding, Claudio denies to marry Hero even after Friar tries to assure him. Hero faints
and is left for dead, except by Beatrice who tries to defend her. Benedick also stays behind (probably for the sake of Beatrice), and it is at the end of 4;1 when Beatrice puts an ultimatum on Benedick: either he kills Claudio, or they will no longer speak. This shows that women have some form of power (as they do in Macbeth for instance, by the art of manipulation and persuasion) over men, as Benedick decides to do it.
Setting changes to a prison cell, and it is in this dark setting that the truth of Dogberry is shown:
''...and a rich fellow enough, go to, and a fellow that hath had losses..''
This leaves the thought that every character has a past that is not shown on stage. Perhaps it was Shakespeare's way of leaving an audience to realise that there really is more going on in people's lives than from what is witnessed - as the whole plot of the play is.
