Confusion!

Helena finds Lysander sleeping in the woods and when he wakes, he finds her irresistable.

But she thinks he is playing a joke on her, and reminds him that Hermia is his love!

Meanwhile, Puck plays a trick on one of the actors...

And Titania sees him first upon waking and dotes on him, even having her fairies attend him.

Fortunately, through the efforts of Oberon and Puck, all is put to rights by the end and each couple ends up as intended: Hermia with Lysander, Helena with Demetrius, and Titania with Oberon.
