Lily B on the brink of Paris

Lily B is on a school trip to Paris with her French class and she is certain that she'll find inspiration for her future novel. Her dream is to become a famous writer some day. She has an experience of her life, flying on a plane and using a phone for the first time of her life! There are 9 passengers on this trip including the teacher, Madame Chavotte.

On one of the days while staying in Paris, the group is meant to meet at the Louvre at 1pm sharp and Madame Chavotte specifically instructed them to only separate into 2 groups (girls and boys) if necessary and they should NEVER be separated from their group. If this ever happens then the whole trip is cancelled! They have the whole morning to explore Paris, so as told they split up into two groups. After exploring they settled at a cafe for lunch then headed to the subway. As they were walking Lily was thinking about her future novel and blocked out every other sound she could hear except her own thoughts. A train stopped by and the doors opened. Lily stepped in. However she only realized that her friend had been saying words like. Wrong. Direction. Train. Guys. Other. Side. But it was far too late, she was down the tunnel and separated from her group. Will she ever find her way to the Louvre?
