<P> Elsa has literally frozen Storybrooke , and hopes to find her sister , Anna ( Elizabeth Lail ) . She accompanies Emma Swan ( Jennifer Morrison ) to try to break down the wall of ice she created around Storybrooke , but her powers are n't strong enough to melt the barrier . The two , along with Hook , pay Gold a visit and to find out if he has known Anna based on the necklace Elsa found in his pawn shop . Belle uses the fake dagger to `` command '' Gold to tell the truth but it fails , as he knows nothing about Elsa or Anna , and wishes them the best of luck finding her . At the same time , Robin Hood ( Sean Maguire ) , Marian , and Roland visit `` Any Given Sundae , '' where the Snow Queen ( Elizabeth Mitchell ) serves them ice cream , but unknown to them she casts a spell on the ice cream cone that she gave Marian . Afterwards , the family joins the other residents at the Mayor 's office , as Mary Margaret ( Ginnifer Goodwin ) , who is still trying to balance both maternal and mayoral duties , is holding the first annual `` Mayor 's Fireside Chat , '' where she assures the citizens that they are no longer afraid of Regina 's influence , but it appears that they want Mary Margaret to do something about the town 's snowy fiasco . Mary Margaret then tells the residents about Elsa 's presence in Storybrooke and is trying to reassure everyone that she is not dangerous , only to have Marian beginning to start feeling as if something was glossing over her and she passes out . Elsa 's presence has also resulted in her becoming a prime suspect , and with her heart slowly freezing , a cure must be found before Marian 's heart completely freezes and kills her . The Storybrooke residents blame Elsa , who is being framed by the Snow Queen for the icy cold mayhem . With the entire town ready to go after their newest addition , Emma ( who starts to question her abilities as `` The Savior '' ) and Hook decide to hide Elsa at the sheriff 's office while she and David search for the real suspect . </P>
