Polly and Isabelle gave the painting back to Monsieur Dupont. The old artist was very thankful. Polly and Isabelle felt proud. But soon, something unexpected happened. As they were leaving the studio, they heard noise outside. They looked and saw the busy streets of Montmartre. A group of street performers was there. They wore bright costumes and did exciting tricks. People stopped to watch them. One performer was a mime. He made funny faces and moved silently. Polly and Isabelle were not interested in the show. They were curious about the crowd's excitement. Polly moved closer to see better. Her bright feathers shone in the light. Then she saw a familiar face. It was Isabelle's younger brother, Henri. He was supposed to be at home in Lyon. Seeing him in Paris was a surprise. Isabelle called out to him, moving through the people. Henri was tall, with messy hair and a cheeky smile. He was surprised to see Isabelle too. "Henri! What are you doing here?" Isabelle asked. Henri looked away, feeling shy. "I wanted to see Paris before summer ends," he said. "But I got lost." Polly felt the tension and made a funny noise. "Paris is full of surprises, right?" she joked. Her joke made everyone relax. Isabelle stopped worrying and understood Henri. She saw their meeting as a lucky chance. "Since you're here, join us for the adventure," she said kindly. Henri felt happy and nodded quickly. Polly, Isabelle, and Henri walked together. The colorful streets of Paris promised more surprises.
