recognize the actress playing erin in someone great! the casts of glee, crazy ex-girlfriend, and south of nowhere. any glee castmate for an ex line (blaine is a plus for the fan hate it would've gotten). the actress who played tracy in thirteen. i've got plenty of pb suggestions if needed. selena gomez or cierra ramirez for her sister. connie britton or someone similar (nicole kidman roles or jamie babbit directing credits?) for a line.
