Whereas Leta is a mix of Letha from Hemlock Grove and Effy Stonem or Bellatrix Lestrange. lets go the route that Newt meets her, who ran from her family to avoid a betrotal or something, instead of meeting Tina...from there they get both entangled with the 'situation ' of Modesty and Credence from there onwards. Newt wants to help Credence, Leta wants to help Modesty be cause she is magic and She can emphatize with the abusive parents angle...but the past between Leta and Newt makes it hard to work together. just give me this Au version of the movie and I will be super happy. The world needs this
