As Puck flies off to seek the flower, Demetrius and Helena pass through the glade. Oberon makes himself invisible so that he can watch and hear them. Demetrius harangues Helena, saying that he does not love her, does not want to see her, and wishes that she would stop following him immediately. He curses Lysander and Hermia, whom he is pursuing, hoping to prevent their marriage and slay Lysander. Helena repeatedly declares her adoration for, and loyalty to, Demetrius, who repeatedly insults her. They exit the grove, with Helena following closely behind Demetrius, and Oberon materializes. He declares that before the night is out, Demetrius will be the one chasing Helena.
Puck appears, carrying the flower whose juice will serve as the love potion. Oberon takes the flower and says that he knows of a fragrant stream bank surrounded with flowers where Titania often sleeps. Before hurrying away to anoint Titania’s eyelids with the flower’s juice, Oberon orders Puck to look for an Athenian youth being pursued by a lady and to put some of the juice on the disdainful youth’s eyelids, so that when he wakes he will fall in love with the lady. He informs Puck that he will know the youth by his Athenian garb. Puck agrees to carry out his master’s wishes.
After her dancing and revelry, Titania falls asleep by the stream bank. Oberon creeps up on her and squeezes the flower’s juice onto her eyelids, chanting a spell, so that Titania will fall in love with the first creature she sees upon waking. Oberon departs, and Lysander and Hermia wander into the glade. Lysander admits that he has forgotten the way to his aunt’s house and says that they should sleep in the forest until morning, when they can find their way by daylight. Lysander wishes to sleep close to Hermia, but she insists that they sleep apart, to respect custom and propriety. At some distance from each other, they fall asleep.
Puck enters, complaining that he has looked everywhere but cannot find an Athenian youth and pursuing lady. He is relieved when he finally happens upon the sleeping forms of Lysander and Hermia, assuming that they are the Athenians of whom Oberon spoke. Noticing that the two are sleeping apart, Puck surmises that the youth refused to let Hermia come closer to him. Calling him a “churl,” Puck spreads the potion on Lysander’s eyelids, and he departs.
Simultaneously, Helena pursues Demetrius through the glade. He insults her again and insists that she no longer follow him. She complains that she is afraid of the dark, but he nonetheless storms off without her. Saying that she is out of breath, Helena remains behind, bemoaning her unrequited love. She sees the sleeping Lysander and wakes him up. The potion takes effect, and Lysander falls deeply in love with Helena. He begins to praise her beauty and to declare his undying passion for her. Disbelieving, Helena reminds him that he loves Hermia; he declares that Hermia is nothing to him. Helena believes that Lysander is making fun of her, and she grows angry. She leaves in a huff, and Lysander follows after her. Hermia soon wakes and is shocked to find that Lysander is gone. She stumbles into the woods to find him.
Act II, scene ii introduces the plot device of the love potion, which Shakespeare uses to explore the comic possibilities inherent in the motif of love out of balance. Oberon’s meddling in the affairs of humans further disrupts the love equilibrium, and the love potion symbolizes the fact that the lovers themselves will not reason out their dilemmas; rather, an outside force—magic—will resolve the love tangle.
The ease with which characters’ affections change in the play, so that Lysander is madly in love with Hermia at one point and with Helena at another, has troubled some readers, who feel that Shakespeare profanes the idea of true love by treating it as inconstant and subject to outside manipulation. It is important to remember, however, that while A Midsummer Night’s Dream contains elements of romance, it is not a true love story like Romeo and Juliet. Shakespeare’s aim is not to comment on the nature of true love but rather to mock gently the melodramatic afflictions and confusions that love induces. Demetrius, Helena, Hermia, and Lysander are meant not to be romantic archetypes but rather sympathetic figures thrown into the confusing circumstances of a romantic farce.
Like much farce, A Midsummer Night’s Dream relies heavily on misunderstanding and mistaken identity to create its humorous entanglements. Oberon’s unawareness of the presence of a second Athenian couple—Lysander and Hermia—in the forest enables Puck’s mistaken application of the flower’s juice. This confusion underscores the crucial role of circumstance in the play: it is not people who are responsible for what happens but rather fate. In Hamlet and Macbeth, oppositely, Shakespeare forces his characters to make crucial decisions that affect their lives.
Much of the comic tension in this scene (and throughout the rest of the play, as the confusion wrought by the love potion only increases) stems from the fact that the solution to the love tangle seems so simple to the reader/audience: if Demetrius could simply be made to love Hermia, then the lovers could pair off symmetrically, and love would be restored to a point of balance. Shakespeare teases the audience by dangling the magic flower as a simple mechanism by which this resolution could be achieved. He uses this mechanism, however, to cycle through a number of increasingly ridiculous arrangements before he allows the love story to arrive at its inevitable happy conclusion.
