Demetrius: The Suitor Who Is Still Under the Spell at the End

Demetrius arrived in Act 1, Scene 1 with every social advantage: Egeus's approval, Athenian law, and a determined father's support. He had also, before the play begins, courted Helena and apparently made promises to her. Helena mentions this specifically, which is why his current preference for Hermia looks less like inconstancy than deliberate abandonment.

He is not charming. He tells Helena in Act 2, Scene 1 that seeing her face makes him sick, threatens violence if she follows him further, and is generally graceless until he falls under Puck's spell. The enchanted version of him, adoring Helena, is a significant improvement.

There is one detail in Act 4 the play drops almost quietly: everyone else has their enchantment removed, but Oberon never removes Demetrius's. He wakes still loving Helena, and stays loving her through the rest of the play. His marriage is the only one in the final act built on a spell that is technically still in effect.
