As they walk down the streets of Storybrooke, Robin shows Marian around Storybrooke and explains the new world she is now in, Roland asks his mother for ice cream and they go to Any Given Sundae to get some. Ingrid serves Robin and Roland some ice cream, and while making one for Marian, she uses her magic to secretly cast a spell on the ice cream and then gives it to her, she smiles as she watches the trio leave the shop.
Meanwhile, Emma, Hook, and Elsa are in Gold's shop, with Gold and Belle standing in front of them, hoping that Gold might have an answer to why Elsa was in the urn in his vault. Gold says that if Emma wants to know how Elsa ended up there, then ask her herself, "She did," Elsa interrupts, "but I don't remember. Something happened to my memories."
Gold points out that many objects fall into his position and that he doesn't know the history behind all of them. "Who gave you the urn?" Elsa asked him, Gold is silent, he then asks her what she will do once she finds the person who placed her in the urn.
"That's between me and them,"
Gold explains that he found the urn, which was abandoned near the Enchanted Forest before the curse, and suggests that Belle use the dagger on him to prove he is telling the truth.
"The truth is just as I said. I had no idea there was someone inside there. I know nothing about Elsa or the Kingdom of Arendelle." He replies to them.
As Emma, Hook, and Elsa leave the pawn shop, Gold stops Emma. "Are you sure you want to help our new friend, Ms. Swan? It looks like revenge is still what she's after. That sounds like the path of a villain."
"Then, I'll show her a better path than revenge." Emma says and then leaves the shop.
Over at the mayor's office, Mary Margaret is holding a town meeting while taking care of Neal. The town is upset over Elsa's mayhem while Mary Margaret, David, and the Hood family defend her. As they speak, a strand of white begins to frost into Marian's hair and she collapses, however, Robin catches her, where he notices the white strand of Marian's hair.
At Granny's Diner, Henry is sipping on a mug of hot chocolate when Regina comes in and puts down some comic books for him. He is happy over her gift, to which Regina remarks that she wasn't sure which kind he liked anymore, so she got a bunch. As Henry begins flipping through one, Regina questions him about the writer of his storybook. Henry then begins to wonder why she is asking. she wants to ask the author to rewrite a happy ending for her. Henry agrees to help her find him, and the two decide on the name of the mission to be "Operation Mongoose". Robin bursts into the diner and requests that Regina help Marian.
Regina and Robin rush to the mayor's office, where Regina studies what is going on with Marian. Emma, Hook, and Elsa come to the mayor's office later, where Mary Margaret is taking care of her.
Regina assumes Elsa had something to do with it but Elsa tells the other queen that is not her magic, Emma believes Elsa, who tells them that the only way to break a freezing spell is an act of true love. Robin kisses Marian, but nothing happens.
Emma decides to go and find the one truly responsible for the spell on Marian, Regina then asks her to take backup because it seems like the town was more busy saving the savior than the other way around. Emma asks Regina not to lash out at her and tells Killian that she can manage it on her own. She asks David to come with her and she tells Hook to stay out of it and take Elsa to the sheriff's station.
Outside Granny's Diner, Leroy has his meeting with Granny, Archie, and other people; he tells them that Elsa is the problem and they need to stop them. As Leroy and Granny start walking away, Archie stops them, stating that they cannot just condemn her without all the facts. Leroy tells the therapist to look around, "Who else can turn people into popsicles?" he asks. "It's Elsa, and we all know it. She has got to be stopped before she hurts someone else."
The group continues to walk down Main Street, passing "Any Given Sundae" and the Snow Queen, who watches them pass with a smile on her face.
Hook and Elsa hide in a narrow alley; the pirate checks to see if the coast is clear, it is, and he prepares to lead Elsa, who has a different idea. Elsa tells him that there is someone out there with powers like her, and she needs to find out who she hides out in a sheriff's station. Hook tells Elsa that she's lucky because they're not going to the sheriff's station, and Elsa asks what direction they're going. "With any luck, danger." Hook begins walking with Elsa following behind him, now intrigued.
Meanwhile, in the woods, Emma and David approach the Merry Men's campsite; Emma tells David that whoever cursed Marian has the same powers as Elsa, so maybe they left a trail. David suggests they split up and look for anything cold. Emma discovers an intruder in Robin and Marian's tent, who almost escapes, but is captured thanks to David.
The intruder is revealed to be a woman who has long dirty blonde hair, wearing a black leather jacket. Emma asks who she is, and she tells them that she is just a nobody living in this town, but she does gives them information that relates to what happened to Marian, explaining that during the blackout, she went to the ice cream shop, noticed it was empty.
She explained that curiosity got to her, went to the back and saw the ice cream was still frozen after there was no electricity for hours. They check the ice cream shop to see that she is right. However, when they realize she was telling the truth, she escapes and Emma tries to follow run after her, but David stops her as whoever owned this shop is more important that the intruder.
Back in the mayor's office, Regina tells Robin that the ice is making its way to her heart at the mayor's office and that once it touches her, she's dead. Robin asked if there was anything she could do. Regina reveals that there might be something, but Robin would have to trust her completely, and he does "Then I'll send Henry to my vault to get what I need," Regina replies. Robin asks Regina what she is going to do, to which she replies, "Something drastic."
Meanwhile, Hook and Elsa visit Gold's shop, who denies helping them unless he has something to offer, Hook informs him he has one thing to offer, his silence. He knows that Belle never had the real dagger as Gold would never let anyone have power over him, including Belle. Mr. Gold accepts and performs magic on the strand of hair turning it into snowflakes.
"Magic similar to yours, dearie, though not quite the same. Much like a snowflake, each person's magic is unique," Gold then explains to them that it will return to its source. He blows the snowflakes into the air and flies out of the shop. Killian and Elsa follow the snowflakes. They follow them to the forest when they notice ice on the trees and ground, letting them know they're on the right track. They see a figure walking through the woods. Hook pulls Elsa down to the ground with him, hiding from the Snow Queen. Elsa is amazed by her as she uses her powers. Hook pulls out his phone and leaves a message for Emma that they found who cursed Marian and they are in the forest.
After watching the woman for some time, Hook decides to go find Emma, but he is unable to move. He looks down and sees his feet frozen to the ground. "I'm sorry, but I'm afraid I can't let you leave," the Snow Queen says, standing behind them, her back against them. She demands the Snow Queen let go of Hook, but she refuses. "Not when you and I have so much caught up to do, my sweet Elsa." She tells Elsa.
"Catching up? You know her?" Hook asks, Elsa tells Hook that she has never seen her before, but the Snow Queen corrects that she has simply forgotten. Elsa doesn't believe she could have possibly forgotten someone like her. The Snow Queen explains to Elsa that her memory has been wiped out by the Rock Trolls, making Elsa wonder why they would do that to her. The Snow Queen tells her that some memories are just too painful, revealing it to be the moment she was placed in the urn, revealing she was there when it happened and it was done by someone who didn't understand her magic and saw her as a monster and not a person.
"Eventually... they grow to fear us. This person was afraid of you and your magic. So they trapped you in that urn. I know... I was there that day, and I punished her for it. They will never understand us, they will always see us as monsters. Look at the people in this town. They're ready to burn you with a steak." Elsa points out that the reason is that she was the one who did it to Marian. The Snow Queen tells Elsa that what happened to Marian was an accident, which Elsa sees as another lie, and asks her why the Snow Queen wanted them to blame Elsa.
"You and I are more powerful than you think. Join me, I'll teach you how to truly control your magic without your fear controlling you. With our magic combined, we can show this world we are the most powerful people of them all."
"But, they will be scared of us," Elsa tells her.
"Just like your parents were to you. Now come with me; it's the only way." Elsa then suddenly asks how the Snow Queen knows her parents, who tell her the people she loves will always be scared of them and will one day turn on them.
The Snow Queen sees in Elsa's eyes that she is considering this, "I understand if you don't, but take this," She shows Elsa a piece of paper with something written on it, "You want them, don't you? That's why you ended up in this town, to find whoever placed you in that urn and make them pay. I have good news for you, they are in this town, living their best life, believing they actually got away with what they did you. Do what your parents have always told you..."
Hook stops her telling her that he too was in the path of revenge of a long time and it changed who he was. "If you choose this path, it will change you. There's no going back to who you used to be."
The Snow Queen places the paper in Elsa's hand, closing it, "Deep down, you know this is the right thing to do." She whispers to Elsa before she uses her magic to form ice shards to form over Hook, aiming toward him. Elsa asks what she's doing as she tries to use her magic to stop this. "Don't worry, I've neutralized your magic. When your friend is found, they'll think you're responsible, and they'll turn on you. They'll treat you as the monster they truly see you as, and you'll know that I'm right, and hopefully, you will join me,"
Emma and David come to their aid, and the Snow Queen becomes surprised to see Emma; uttering her name, Emma asks if they know each other, which the Snow Queen denies as her response, "Your reputation proceeds you. You think your magic is a match for mine?" she asks. "There's only one way to find out," Emma exclaims before using her magic to knock the Snow Queen to the ground. David rushes over to Hook and tries to help him.
The ice spikes above them begin to lower just as David uses his sword to try to free Hook from his trap. The Snow Queen looks up and uses her magic to make them drop, but Emma uses her magic to try to throw David and Hook to safety, but this knocks the Snow Queen back. However, Hook is still stuck on the ice. Then, three arrows made of ice that came from the woods are shot towards the ice keeping Hook stuck, which cracks it, freeing him. David and Hook run from the spot where the spikes come down, shattering into millions of pieces.
David looks around the forest and notices that the Snow Queen is gone. Later, Emma returns, explaining that she found motorcycle tracks and footprints a couple of feet from where they were, and theorizes it came from the person who helped them. David then sees that something is wrong with her. He tells her they will find the Snow Queen and encourages her not to let Regina make her doubt herself. Emma replies, "It's not that, it's this Snow Queen. She didn't just know Elsa; she knew me too." Emma continues, "There's something more. When she said my name, it sounded familiar." David reassures her that they will figure it out but tells her she did well today. She stopped the Snow Queen.
Hook suggests they find the Snow Queen's lair, but Emma stops him. She warns him that he could get himself killed again and explains that is why she wanted him to go to the sheriff's station. Before she walked away from Hook, he tells her that the Snow Queen gave Elsa the address of the person who put her in the urn. He says, "If someone should talk her down, it should be you."
Emma joins Elsa, who is inspecting the ice arrows, and she asks her about the note the Snow Queen gave to her. Emma suggests that they should go to the house the Snow Queen wrote on the paper so they can investigate the house and learn about who lived there as a way for Emma to keep an eye on Elsa, and see if she's still wanting revenge on this person.
The four drove to the house the Snow Queen wrote on the address. The house was located just near the town line where the ice wall was, Emma and David were the first ones to get into the house, checking each room, and discover that nobody was in this house. David wonders of the possible reasons behind this empty house.
"They heard the news Elsa was in town, realizing that she was probably after them, so she must have tried to leave town. She could still be in town, or there's a chance she might have found a way to get through the ice wall."
Emma and David then called Hook and Elsa to get them into the house, where they let Elsa walk through the house, and they watched her as she walked into each room. David tells them that he knows his technique as a way to get to know this person before hunting them, which was something Mary Margaret used to do back in the Enchanted Forest. They make their way into the living room where they see a to go box with sandwiches that Emma sees is from Granny's and a cup of hot chocolate.
The three searched each room, trying to find the owner of the house; when they got into the bedroom, they discovered a sword shield decoration with the crest of Arendelle, confirming that this person was someone from Arendelle. They then find the person's phone answering machine, where they see it has tons of missed calls along with voicemails. From the voicemails, they learn the person's name is Summer Pheonix.
They then head out the house, going back in their cars. In the yellow bug, Emma asks Elsa what she's going to do now after learning the person's name, "I'll follow your lead," Emma asks if she's sure with that and Elsa replies that she is. "Ok, I'll take your word for it," The two cars then drive away from the house. Inside the car, Elsa secretly uses her magic to cover the entirety interior of the house with ice spikes, destroying some of the things that were in its path.
Visual Imagery: After the cars left, a motorcyclist drives and stops to the house, only their body, neck down is shown. They watch the cars drive away until they were all gone, so they go to the front door. They use their left arm to open the door, but its jammed. But when they use their right arm, the doorknob breaks, allowing them to get into the house, which was covered in ice spikes. They head to the bedroom, where the drawers were destroyed due to spikes, and a doll with braided strawberry blonde hair, a crown, and it was wearing a green dress with a pink bow was stabbed by the spikes. The person removes the doll from the spikes, and walks away, leaving the house.
Regina and Robin are still in the mayor's office with a now completely frozen Marian. Henry enters the room, with a box in hand, Regina asks if Robin is still sure he wants her to do this, Robin nods and Regina then thrusts her hand into Marian's chest, ripping out her heart. Regina notes the ice hasn't touched Marian's heart yet, so they can keep her alive. Henry holds out a box for Regina to put the heart in, and Robin asks if his wife will remain in this state, alive, but frozen. Regina nods, "Until we find a cure. And I will find one. I promise."
Outside at Granny's, Hook asks Emma to have a drink with him, but she says no. He follows her and says he understands how heavy her burdens are and why she finds it hard to trust him. He learned this from Elsa. Emma explains that her concerns go beyond trust; she is afraid. She fears that anyone she loves will die, just like those she loved before him.
"Well, love, you don't have to worry about me. If there's one thing I'm good at, it's surviving." He then pulls Emma in close, kissing her in the middle of the street.
In the woods of Storybrooke, the Snow Queen is walking alone when she hears a noise. She turns around and sees Gold waiting for her. "Don't worry, dearie," Gold says. "It's just me. Let's talk." He apologizes for things not going the way she wanted.
"They will," the Snow Queen says. "We shall see." He then asks Emma if she knows the Snow Queen, but she replies she does not. The Dark One comments that this is good for her because it could be dangerous. He adds, "Someone saved her pirate and father. We both know exactly who it was, dearie." The Snow Queen agrees. Gold then asks why the Snow Queen hasn't come to him for help with her plan and to trap whoever interfered "I'm not the one after her; someone else is doing it for me," the Snow Queen says. She tells him that she will come to him when she's ready to make a deal.
"A moment I eagerly await. Now, you should find some shelter. It's getting quite frosty." He walks away and leaves the Snow Queen all alone in the woods.
