They all came back to Gold's shop after Emma called them. "What is it? She said you found something", Snow asked Gold. Gold waved to the mirror and showed them Regina's dream. "This memory of her is running in her mind on a loop", he answered. They watched that memory of her. It is in the stable, the night Regina and Daniel are going to run away but Cora arrived and stopped them. "Oh my god", Snow muttered because she already know what's going to happen. Then Cora ripped his heart and crushed it in front of Regina. "Mother!" she called and rushed to his body but it's too late. He's dead. They watched Cora forced her daughter to marry the king. "Now clean yourself up. Wipe your tears. Because tomorrow, you're going to be a queen", she said to her.

Gold stopped it. Snow can't help it but burst into tears. "Are you okay?" Emma asked her and she shook her head. "That was my fault. I told her mother about Daniel. I knew that she killed him but I didn't know it was like that. She killed him in front of her and it's my fault", Snow answered. The room went quiet. "Any ideas why that memory of her is playing in her mind?" Hook asked. Gold took a seat. "Shadow of Zion is not only known for devouring the life of dark magic users. It is also known of devouring their emotions, their strengths, and weaknesses", he answered. Belle stepped forward. "That's true. In this case, that memory is what started it all for her. It gave her strength to survive and seek revenge but it's also her weakness. It brings emotion back to her heart. Playing that over and over in her head, that's the most terrible torture of all, to relive the darkest moment of your life", she explained.

They all looked at Regina who is still in a dream of her own memory. She is looking pale than before. "It's killing her from inside", Emma muttered. They all scattered trying to find a way how they're going to wake her up. Emma and Snow went to the fairies for help. Blue is not very fond of Regina and is reluctant to help them but Tinkerbell persuaded her to help. "There's one way to wake her but it's dangerous", Blue said. It sparked hope in Emma's eyes. "What is it?" she asked with anticipation. "Someone has to go inside her dream and tell her it's all in the past. You have to understand, she is reliving it again and again. She thinks it's happening at this moment", she answered. Emma looked at her mother. "Tell me how to do it", she said to Blue.

Once they learnt how to wake her up, they rushed back to Gold's shop only to find it all messed up and Regina's gone. Belle helped Gold to get up. "What happened here? Where's Regina?" Snow asked. Robin grabbed his bow and arrow. "She woke up", he answered. The two ladies got surprised. "That is great news, right? Because you don't look like you're thrilled she's back", Emma said. "She is a bit confused. No, not a bit. She's very, very confused", Belle said. Emma frowned. "Well, how confused?" she asked. Gold looked at her. "She doesn't know who we are or where she is", he answered. She looked around the shop and it's all wrecked. "Apparently, I don't think she knows how to use magic too", she muttered based on her observation on the place.

Emma and Snow scoured the entire town for her but they couldn't find her. Then Snow's phone beeped. "It's David. They found Regina", she said to Emma who is driving her bug. "Where?" she asked. Snow looked at her. "At the town line", she answered. Emma looked back at her. "Oh god…if she crosses that line, she may not be able to come back", Emma muttered. They arrived at the town line and saw David with Hook trying to persuade a very confused Regina not to cross the border. "Regina", Emma called. She looked at her. "Who are you people? Why do you all know me?" Regina asked. "Gold was right. She doesn't know any of us", Snow muttered. Emma looked at her. "That's not true. She knows you", she said. David heard that. "Are you kidding me? She remembers that I was the one that got her boyfriend killed", Snow exclaimed. They saw Regina's powers being out of control. A bolt of electricity hit the streetlight. "I know but think about it. At least, it will give her some sense of where she is. We just need her attention so she wouldn't cross the town line", Emma explained.

Even though she thought it was a bad idea, Snow agreed to it. She stepped forward. "Regina, I know that you don't know us but I know you and you do know me. My name is Snow…Snow White. Do you remember?" she said to her. Regina frowned at her and looked at her carefully. "Snow? But how did you grow up so fast?" she asked. Snow smiled. "Trust me, I didn't grow up fast. I can explain everything if you come with me", she answered. Regina looked around. Robin and the others arrived at the town line and saw what's happening. "You can trust me", Snow said. "I did that. I did put my trust in you but you betrayed me", Regina said. Emma readied herself. "You told Mother about me and Daniel", Regina added. Everyone tensed up. They don't know what's going to happen next. "I know and for that I am so sorry. I was wrong despite of my intention but I promised you now I am not going to betray your trust. I just want to help you", Snow said.

Regina believed it and walked towards her. There's one problem remaining, her powers. She can't control it. "What is happening?" Regina asked them. "It's your magic", Emma answered. She looked at her. "I am not supposed to have magic", she exclaimed and panic. It gotten worse. "Regina, you need to calm down", Emma said but she cannot do it. The others hid behind the car due to the lightning bolts coming out of her hands that are flying everywhere. "Regina you have to relax", Snow said. "I can't!" Regina said. Then Robin grabbed her hands and held it despite the electricity. "Look at me. Just look at me and nothing else", he said to her and she did. "That's good. Now breathe, Regina. You can do it. Just breathe", he added and she followed. Slowly her powers subdue and the bolts disappeared from her hands. She finally calm down. She then looked at Robin's hands. "Your hands…I'm sorry", she apologized. He smiled at her. "Don't worry about me, milady. I am tougher than I look", he joked and it made her laugh. "I'm Regina", she introduced herself. "Robin of Locksley, at your service", he said as if he hadn't introduced himself to her before. "The thief…oh, I didn't mean to be rude. It's just what I heard. You're quite famous, you know", she said and then smiled.
