Kelly, in her compassion for Berke, lets herself be almost reduced to Berke's social whipping girl as she progressively deepens her bended knee of love to him. But Berke has no interest in Kelly, at least not the same interest she has in him. Some quite underhanded and unethical maneuvers are used by Berke and Striker in their campaigns of love warfare. After losing Allison, Berke slowly goes berserk as he sees Allison becoming progressively infatuated with Striker. Striker gets a key role in the school play along with Allison.
Striker milks the opportunity for all it is worth.
All the while, a relationship develops between Kelly and Berke. He chased her and chased her until she finally caught him. And while all this was happening, Allison comes to her senses and finds out the truth about Striker and offers to Berke a rekindling of their previous relationship. But by this time, Berke sees Allison for what she is and also sees Kelly for what she is. And he tells the audience of his discovery by modifying, or ad libbing, the script to accommodate announcing his new feelings for Kelly.
