During rescuing Henry in Neverland, Emma hears the sound of the flute pipes played by Pan.
It draws her in and for a few days she is a lost girl amongst the lost boys. Emma and Henry don't realize they are anything besides fellow lost people.
During down time, the lost boys like to street fight. Emma, still under Pan's haze, takes to street fighting, as it is the only thing she knows how to do; from her days living on the streets before Neal came along. Emma gains respect from the lost boys, makes her feel accepted.
No Pan curse. Once they are all back in Storybrook, the lost boys create an underground fight club.
Emma finds herself angry at the fact that her parents want another baby and Neal won't take the hint that she doesn't love him anymore. Emma follows one of the lost boys, thinking he is up to something, and comes upon an illegal fight club and decides to fight.
From then on, she is now a member of the fight club.
Regina is the first to notice Emma's mysterious injuries from fighting.
What will it take for Emma to realize she is hurting the people around her, and influencing Henry with her bad coping skills?
