Rosie prepares for her evening with Lucas at the Halloween masquerade ball. She answers the door when it rings and finds Lucas in a formal, old-fashioned suit that accompanies her Victorian gown; they are dressed as the couple from their favorite vampire drama. Rosie is overwhelmed by her attraction, and Lucas comments on her beauty in Spanish. The two gaze at each other as Rosie helps Lucas with his costume.

Rosie is stunned when Lucas presents her with a corsage, likely due to her telling him that her prom date never gave her one. He tells her to “consider it part of phase two. Exploring the spark”—which makes her sad her since it implies his gesture is only meant to inspire her writing (220). He suggests he left the apartment to avoid seeing her undressed, but Lina interrupts before he can explain himself further. At the event, Rosie experiences some of her usual envy at Lina and Aaron’s open adoration of each other, but Lucas distracts her. The event feels “as if [they are] on a double date” (224).

Lucas is overwhelmed by the crowd at the ball, as well as his desire to kiss Rosie. He longingly watches Rosie dance with Lina, and Aaron offers his support.
