Flower of this purple dye, hit with Cupid's archery
I do hate thee and love Helena
But you must join in souls to mock me too?!
Oberon realises Puck mistakenly put the potion in Lysander's eyes. Oberon tells Puck that he must resolve the situation by bringing Helena to him. Meanwhile, Oberon will infect Demetrius with the potion so that when he wakes, he'll love Helena.
I will not trust you!
You canker-blossom! You thief of love!
Oberon puts the love juice in Demetrius' eyes and Puck returns with Lysander and Helena. Demetrius then wakes up and also falls in love with Helena. They then start arguing over her and then start telling her they love her. Helena thinks that they are mocking her.
Hermia then arrives and asks Lysander why he abandoned her in the forest. Lysander tells Hermia that he hates her and wants her to go. Hermia then accuses Helena of stealing her boyfriend. Helena still thinks that the three of them have all agreed to make fun of her. Hermia and Helena argue about their friendship.
Then Demetrius and Lysander argue over who loves Helena the most. Hermia is convinced that Helena has stolen Lysander. Demetrius and Lysander leave fighting. Helena then runs away from Hermia as she is afraid of her, but Hermia runs after her.
