SEASON PREMIERE: Well, this sure didn’t take long: For this Disney show’s Season 4 premiere, Elsa from Frozen arrives in Storybrooke tonight, played by Georgina Haig, who played the ill-fated daughter, Etta, in Fox’s Fringe. And to say she sports an icy demeanor upon her arrival would be understating the obvious. Also showing up for this multiple-episode story arc: Elsa’s sister, Anna, played by Hollywood newcomer Elizabeth Lail.
