It won't take a Once Upon a Time season 4 very long to put in place a new characters key pair.
Executive producer Adam Horowitz tweeted the first page of the script first season yesterday, revealing that the first episode of the fall will be entitled "a tale of two sisters."
This, of course, is a reference to Elsa and Anna, the brothers and sisters of frozen foods that will reappear on the ABC hit next year and be portrayed by Georgina Haig and Elizabeth Lail, respectively.
Scott Michael Foster has also been cast as Kristoff, with Once Upon a Time season 4 dig deep into this animation Disney smash for future scenarios.
It is not known what kind of relationship Elsa and Anna will be when viewers their encounter, but the casting notes describe the first as someone who can only control his dangerous powers with the soothing influence of her sister.
ABC has yet to announce a date of return for its fall shows, but you can still watch it once was in line to catch up before official frozen presentations are made.
