I have to answer this question for my analysis, Im not sure how Helena can affect others with her changes
We aren't sure if Helena actually changes. When Demetrius and Lysander both fall for Helena via love potion ,she can't believe she is worthy of attention. By the end of the play perhaps Helena feels better about herself with Demetrius (now off the love potion) still in love with her. Still, Helena is skeptical that she is worthy. The question of change really hangs in the balance for all the main characters. Can Helena find confidence? Can Lysander mean up? Can Hermia chill out a little? Perhaps Helena's brush with acceptance might help the others as well.
