Inside Gold's Shop, Cora and Snow are doing some research through Rumple's old books of dark magic while Rumple is doing something else at the back of his shop. Emma and David returned from their search for Regina.
"So? Did you find her?" Snow asked her husband and daughter.
"No. They're not in the park anymore. I tried her house and her office. She's not there either. I can't find Henry as well", Emma answered.
"How about her vault?" Cora asked.
"I went there and they're not there as well", David answered.
Rumple came out and saw everyone by the counter. He put a large book on top of the table and Cora went to it.
"Is this what I think it is?" she asked and he nodded.
Cora ran her fingers on the cover of the book.
"What is it?" Emma asked.
"This is the Dark Lord's book. It's been told to hold all of the most powerful spells ever created. The only people who can cast them are extremely powerful witches", Cora answered.
Emma looked at book and tried to touch it but backed off after she felt a certain spark.
"Careful, Savior. This is pure dark magic. It's untouchable by light", Rumple warned.
Snow pulled her daughter to her to keep her away from the book.
"So what does that book is going to do with Regina? Are there spells in there that can help her?" David asked.
"No. I don't think so. I was wondering how she was able to strip Blue Fairy's magic with her own wand so I did some digging. Guess what…the spell she used was in that book", Rumple said.
Cora looked at Rumple in disbelief.
"No. My daughter is not capable of doing spells like this. She is powerful but not that powerful. Besides, I don't think she even knew about this book", Cora disagreed.
"You forgot, dearie. Your daughter lived in my castle for a good amount of time when the king and his daughter were travelling. She stumbled on this in my library but she ignored it because her goal at the time is to bring her love back to life", Rumple explained.
"She must've seen the spell", Cora muttered.
Rumple then turn the pages of the book and stopped at a certain page with the title "The Dark Offering".
"Oh, she certainly saw this", he replied.
Meanwhile, inside Regina's secret room down her vault, Henry brought a bowl of warm water and a towel next to his mother who is lying down the couch. Henry soaked the towel into the bowl and gently put it on top of Regina's forehead.
"Mom, you're really hot. I think we should take you to the hospital", he said.
"No, I can't go in there. I don't think they can treat this anyway", she declined while still shivering.
Henry saw Regina's phone silently ringing on the table. It was Emma calling her repeatedly.
"Henry", Regina called.
"Yes, Mom? Can I get you anything?" he asked.
"No. You should go. You can't stay down here forever with me. I'll be alright in here", she answered.
Conflicted, Henry looked back and forth between her and her phone. Then, Regina passed out.
"Mom? Mom?" he called but she's not waking up.
Henry ran towards the phone and dialed Emma.
"Mom…we need help. My other mom is not waking up", he said.
Henry waited for couple of minutes before he heard Emma and David calling inside the vault. He went to open the door and let them inside the secret room.
"Whoa…I didn't know this underground vault is really this big", Emma muttered.
"I didn't know about this either", David replied.
"My mom is over there", Henry reminded them on what they came for which is Regina.
Emma and David ran to Regina who remains unconscious on the couch. Emma felt her pulse on her wrist.
"She's alive but her temperature is really high", she said.
"We should take her to Gold. He'll know what to do", David said and then carried Regina in his arms.
Cora and Snow prepared the bed at the back of Gold's shop when David, Emma, and Henry arrived with Regina.
"What happened?" Cora asked.
"We were having breakfast and then she dropped the coffee. Her hands won't stop shaking and then she didn't feel good so we went down the vault because she said we can't go to the hospital. I thought she was just having fever and then she passed out", Henry answered.
Rumple used his dagger to determine what's going on with her.
"Well?" Cora asked once he's done.
"I don't know. It's strange. Her magic is fighting her body", he answered.
"What do you mean?" Emma asked.
"What he meant was the darkness is killing her from the inside", Facilier intervened.
They all turned around and saw him sitting behind them. Unlike his earlier appearance to them, he's filled with worry this time. He stood and tried to approach them.
"Take one more step and you'll have the quickest death you won't even notice it", Cora warned.
"I didn't come here to hurt anyone", he said.
"Then why are you really here? Why are you so hell-bent on turning Regina to the darkness?" Snow asked.
"I only serve my queen. I love my queen. After the Dark One banished me into another realm to keep us apart, I keep track on her. I watched everything. I saw her performed the ritual. But then, it was interrupted by you. The ritual was never completed. The curse kept her hidden from me for years until it was broken. Once I saw my opportunity to escape the realm I was locked up in, I took it and went here to help her", he explained.
Emma scoffed.
"You helped her by framing her? I don't think that's called helping", she muttered.
"You have so much to learn, Savior. I did that to save her life", he said.
"What are you talking about?" Rumple asked.
"Once the darkness has tasted you, it won't stop. The darkness likes how she taste. Now, it wanted to finish the meal", Facilier quoted him from before.
"…it will come for her one way or another", Rumple muttered.
Facilier nodded in agreement.
"This whole thing of redemption is going to kill her. The ritual has to be completed. If she continues to fight the darkness in her, the darkness will kill her. It will not let her go. As you can see, it is already starting", Facilier added.
They all looked at Regina who is still unconscious and looking more and more pale as time goes by.
"Your suggestion to save her life is let her be evil again?" Cora asked.
"Exactly…that's the reason why I provided the pirate with the magic bean so you can come here and do that but it turns out you have a different goal which is to make up with her. That makes the whole thing worse", he answered.
Snow kept on staring at Regina. She started blaming herself. It all started with her. If she hasn't told Cora about Daniel, Regina will not turn evil. If she only surrendered long ago, Regina will not be desperate enough to perform the ritual on herself.
"Once we turn her dark, there is no way to know what she's going to do next. She might come after Snow again or the people of this town", David said.
"At least my daughter will be alive", Cora muttered.
"Is that worth of all the lives in this town?" he asked.
"Are you proposing to let my daughter die instead?" she asked him back.
"Maybe that is not a bad idea considering all the things she has done to all of us", David said.
"Dad…" Emma muttered.
"Oh, why don't you go on ahead and die first then?" Cora muttered and produced a fireball in her hand.
"We have to turn her evil again", Snow suddenly said which got everyone's attention.
Cora put out the fire on her hand and David turned to her.
"Do you know what you're asking? If the Evil Queen has been revived, she will come after you", David asked.
"I know. Maybe she will come after me again or maybe not this time. All I know is we can't let her die. Back in the Enchanted Forest when I was still on the run from her, she disguised herself as a beggar to get to me. I saved her from her knights and we spent time in the woods. She has all the chance in the world to end my life right then and there but she didn't. She listened to all my stories. I know there is still good in Regina even at her worst. I believe that. She was the Evil Queen and yet she was able to love Henry. She can turn herself around but first she needs to survive this. We need the Evil Queen back", Snow answered.
"Finally, we all agreed on something", Facilier said.
Regina opened her eyes and found herself in the middle of the woods. She sat right up and looked around.
"Henry?" she called but no one answered her.
She got on her feet and walked around until she reached the park. There she saw the Charmings with Henry.
"There you are", she said and they turned to her. "I was looking for you. Look, I don't know what happened. How did I get into the woods?" she asked.
"…because we left you there", Henry answered.
"What?" Regina asked.
"You are the Evil Queen. You can't be with the heroes because you're a villain. That's why we left you in the woods because that's where you belong", he answered.
Regina shook her head not believing what she's hearing at the moment.
"Henry, what is going on? Why are you saying those things to me? I thought we're clear. I thought you believe in me", she asked her son.
"I was just playing along. It's something I learned from my real Mom. It's meant to throw off the Evil Queen on our trail", he answered.
Regina looked at Emma.
"What did you to my son?" she asked.
"I didn't do anything. He just woke up on who you truly are. We all do. Just to be clear, he is my son and not yours. You're just nothing but a rotten queen who doesn't have anyone but her darkness to feed on. I asked you before why everyone is running away from you. Now I know the answer. It's because no one can ever love you", Emma answered.
"Go away, Regina. Run as far as you can. You have no place here with us. We already have our happy ending, something that you can never have", Snow said.
Tears began falling from her eyes as her heart continues to break. She didn't say a word. She just stood there looking at them memorizing the looks on their faces and then poofed herself out.
"I felt bad", Henry muttered.
"I know, kid…me too, but we have to do that to save her life. I just hope that works", Emma said.
