how did Serena get to Philadelphia

Luis is almost finished with his night club engagement when there is a terribly bad storm and Serena is blown to Philadelphia. She comes down in the Zoo's lake. Louis is wise enough to let her rest and get herself together before he approaches her. He decides to awaken her by playing "Beautiful Dreamer" to her. He plays it and she wakes up to really see him. They began to flirt in a swan way. They swim around each other and then duck heads to one side and then the other of the opposite swan. Louis picks up his horn and plays the song he had written for her. Serena is in love. Finally his lady is in love with him.
