What happens
Oberon discovers Puck has anointed the wrong lover's eyes. When Demetrius and Hermia enter, Hermia accuses him of killing Lysander. Puck then enchants Lysander, who wakes to see Helena and instantly declares his love for her instead of Hermia. Helena thinks they're mocking her. Lysander and Demetrius both pursue Helena while Hermia, abandoned and furious, turns on Helena with physical threats. The scene ends in chaos: the men circle each other arguing, while the women trade insults and accusations.
Why it matters
This scene is the play's turning point—the moment when Oberon's magic plan backfires spectacularly. Puck's mistake of anointing Lysander instead of Demetrius unravels the simple fix Oberon imagined. By having both men suddenly love Helena, the spell doesn't resolve the love triangle; it creates a catastrophe. The speed of Lysander's transformation is shocking. Moments ago he was willing to die for Hermia; now he speaks of her with contempt, his language shifted entirely to justify his new love through 'reason.' This reveals something crucial about the play's logic of desire: love isn't a stable position anchored in the person loved. It's a force that rewrites your entire self, your past, and your justifications. Lysander doesn't gradually shift—he *becomes* a different person when the magic hits, and he's completely sincere in his reversal.
The women's experience in this scene is one of total disorientation. Hermia wakes from a nightmare to find her worst fear realized—Lysander is gone, and she's alone in the dark woods. She becomes savage, accusing Demetrius of murder and threatening to claw out Helena's eyes. Helena, for her part, experiences a kind of cruel mockery that feels worse than rejection: suddenly both men love her, but she can't believe it's real. Her long complaint about how they're united against her—'a confederacy'—captures a truth: when desire is unstable, the person desired becomes a site of competition rather than connection. The scene's tragedy is that all four lovers are trapped in the machinery of magic, each one experiencing a different nightmare. None of them can trust what they see or hear. By the end, the forest has become a place of total confusion where identity itself is uncertain.
Puck's attitude throughout—his delight in the chaos, his 'Lord, what fools these mortals be!'—frames the audience's perspective. We're invited to laugh at the lovers' helplessness, but the laughter covers something darker: the realization that love makes all of us helpless, that desire operates outside reason, and that the self is far more fragile than we'd like to believe. The scene also establishes the play's central conflict: the attempt to impose order (Oberon's plan, Theseus's law) on forces (desire, magic, the forest) that refuse to be ordered. The magic doesn't solve the lovers' problems; it exposes how little control anyone has over their own hearts.
