Final answer:
When Sophie tried to shoot Tedros with the magic love bullet, Agatha intercepted it, causing her to fall in love with Sophie.
Step-by-step explanation:
In the book "The School for Good and Evil" by Soman Chainani, when Sophie tries to shoot Tedros with the magic love arrow, the situation takes an unexpected turn. Instead of falling in love with Tedros as Sophie had intended, Agatha accidentally intercepts the arrow.
Consequently, Agatha becomes the unintended recipient of the love spell, complicating the dynamics of their relationships and introducing unexpected twists into the narrative. This event adds layers of complexity and irony to the story, contributing to the overall intrigue and development of the characters' relationships in the fantasy world of the School for Good and Evil.
