Summary
Chapter Four opens with Lucas waking up in a diner, stiff and embarrassed after spending the night there. He had left Lina's apartment the previous night because he felt he was intruding on Rosie's space, despite her offer to stay. When Rosie finds him, she is concerned and a little annoyed, questioning why he didn't return. Lucas explains that his credit card was missing from his wallet, leaving him with only about fifty dollars in cash, so he couldn't check into a hotel. He had contacted his bank and requested a new card from Spain, but it would take time. Rosie, who had been on her way to Philadelphia to visit her father, spots him from across the street and brings him sausage rolls from a bakery. They share the pastries, and Lucas's playful, flirtatious demeanor gradually wins Rosie over.
To break the ice, Lucas proposes a game: five questions each, with answers exchanged in turn. Rosie agrees. She reveals that she quit her job at InTech, an engineering firm, six months ago. She had self-published a romance novel under a pen name, which eventually led to a book deal. She is nervous about telling her father and brother, fearing they won't understand or support her new career. Lucas shares that he has been traveling across the United States for six weeks, starting in Portland and driving to Phoenix, and plans to stay in New York for six weeks. He admits he missed Lina and Aaron's wedding because he couldn't arrive in time, though he struggles to explain further.
Their conversation is interrupted when Rosie receives a call from her father, who has had an accident and is being taken to the hospital. Panicked, she prepares to leave, and Lucas offers to accompany her, but she declines. She pays for their coffee and pastries, insisting Lucas accept the help, and tells him she'll return to the apartment later to collect her things. As she leaves, Lucas calls out a playful request not to tell her father about the sausage rolls, and she laughs. The chapter ends with Lucas reflecting on his debt to Rosie and his own lack of plans.
