The four lovers are all young, passionate, and romantic.
Helena, spurned by Demetrius despite her love for him, displays low self esteem. She is sad and down on herself, constantly comparing herself to Hermia, whom Demetrius desires.
"Call you me fair? that fair again unsay.
Demetrius loves your fair: O happy fair!" (1.1)
Helena is devoted, as she tells Demetrius of Hermia's plan to flee with Lysander. We might even call her desperate, as she follows Demetrius and will not give up on him despite his repeated statements that he does not love her.
"I am your spaniel; and, Demetrius,
The more you beat me, I will fawn on you:
Use me but as your spaniel, spurn me, strike me,
Neglect me, lose me; only give me leave,
Unworthy as I am, to follow you." (2.1)
Demetrius is fickle. Once engaged with Helena, he now spurns her as he pursues Hermia. He is headstrong, and chases after Hermia even though she and Lysander are in love. He becomes quite mean to Helena when she follows him in the woods.
