Helena wants Demetrius to love her, but Demetrius only loves Hermia. Helena keeps following him to make him love her, and she offered to be his "pet."
Love at Last
Egeus was complaining to Theseus and Hippothyla about how Hermia refuses to marry Demetrius, who he will allow to marry her. Hermia was angry because she loved Lysander, but her father did not want him to marry her.
Titania has an Indian boy who she adopted as an orphan, but Oberon wants to use him as a knight. Titania does not want to give him up, so they get in another argument, and Oberon puts a love potion on her.
Robin Goodfellow was commanded by Oberon to put a love potion on Demetrius, so he fell in love with Helena. At the beginning, Helena believed she was getting mocked by him, but he truly was in love with her.
i love you
To escape their problem with Hermia's father, Lysander told Hermia that they could get married at her aunt's house. They decided that would be best, so they ran off into the forest to escape her controlling father.
After Oberon puts on the love potion and takes the Indian boy from her, he releases her from the potion. They are reunited again, and they dance with each other.
