What is Oberon's role in Acts III and IV of A Midsummer Night's Dream?
Oberon's role in Act 3 is very important because he has set in motion the action that takes place and carries through to the end, specifically the love potion applications that result in Titania falling in love with Bottom, and the mixed-up love among Helena, Demetrius, Lysander, and Hermia. Oberon has asked Puck to apply on Titania's eyelids nectar from a flower that causes the person receiving it to fall in love with the first person spied. He also asks Puck to put the nectar on the eyelids of Demetrius so that he will fall in love with Helena who Oberon has heard proclaim her unrequited love for Demetrius. Puck inadvertently applies the nectar to Lysander's eyes thus setting up the mix-up. Oberon realizes Puck's mistake and asks him to correct it. Oberon's role in Act 4 is that he first of all, orders Puck to remove the ass's head from Bottom because he has what he has wanted (the changeling child and Titania). He has set up the resolution of the play: Bottom, now back to normal, appears with the others in the play to honor Theseus and Hippolyta; Helena and Demetrius are in now love with one another, and Hermia and Lysander are back in love with one another.
