what inspires pity in oberon? act 4 scene 1

Oberon enters and looks at his sleeping Queen. He tells the puck that Titania gave him her young boy earlier in the woods, and so it is time for him to remove the spell from her eyes. Although funny, Oberon feels a little sorry for Tatania sleeping beside Bottom with an ass head. He orders Robin to change Bottom back to normal, but first he wakes up Titania. She at first thinks she dreamed about being in love with an ass, but then sees Bottom still asleep by her side. Oberon helps her off the ground and tells her that tomorrow they will dance at the weddings of Theseus and the other two couples.
