Jessa met Kit through her older brother, Riley, when she was young. Jessa automatically had a crush on Kit but thought they could never have a relationship for a couple different reasons. These reasons included that Kit was older than her by a few years (the book never specified), Jessa's father would never approve because he never really liked Kit, and Kit was her brother's best friend who would also never approve. This symbolizes a face of love as Jessa had to keep her interest in Kit a secret and never could hold a relationship with anyone else.
When Kit and Riley volunteered for the Marine Core, they became Embassy Guards in foreign countries. Once this happened and they both left, Jessa was left basically by herself. This symbolizes the many faces of love as Jessa stayed worried about the well-being of both Kit and her brother as she loves both of them in different ways.
When the Marine Core came and told Jessa that her brother, Riley, had been killed overseas by a terrorist in the embassy, Jessa felt a very paralyzing sense of loss and mourning. At this point, Jessa had already fallen in love with Kit and felt guilty because her brother died while she was hiding her relationship from him. This symbolizes the many faces of love as due to her love for her brother, Jessa now is mourning and heartbroken over the death of Riley.
