Demetrius is stubborn and, one could say, full of himself. Demetrius is in love with Hermia, though she loves Lysander. Demetrius feels he has a right to Hermia, for her father has found favor in him, demanding that his daughter marry him. Demetrius does not take kindly to Hermia's preference and tries to sway them both to his claim, saying, "Relent, weet Hermia, and Lysander, yield/Thy crazed title to my certain right" (1.1.91-92)
Lysander is willing to help Hermia defy Athenian law and her father. He speaks with a lover's cooing words, for example, 2.2.47-48, in which he croons, "One turf shall serve as pillow for us both;/One hear, one bed, two bosoms, and one troth."
