This chapter is for swanqueen927654 with the prompt: "Emma kills Regina (because someone controls her with some kind spell or has her heart, Gold, Blue, or even Snow) you can decide if Emma saves Regina, like splits her heart in two, or she doesn't save her."
Prepare yourselves.
Emma sighed in relief as she walked into the house. It had been a long day at the station, and she was more than ready to curl up with her wife and go to sleep.
"Regina?" Emma called. "Are you home?"
"She's upstairs sleeping," a voice said from behind Emma.
Emma spun around and faced the voice. Gold walked out from the shadows in the creepy way that only the Dark One could. "What are you doing here?" Emma asked.
"Taking care of some business," Gold said, stalking slowly towards Emma. "Some business that requires something from you as well as our dear queen and mayor."
"They're the same person," Emma said, taking a step away from him.
"Regina chose to separate herself from the Evil Queen, making them two different people," Gold said. "But no matter. Either way, they'll both be dead soon."
Emma's eyes widened. "I won't let you do that."
"Oh I won't be doing it," Gold said. "You will."
"Like hell I will," Emma said. "I'm not going to kill my own wife."
"What if it was to save your son?" Gold asked, waving his hand. Henry appeared in the room, his hands tied and his mouth gagged.
"Henry!" Emma exclaimed, taking a step towards him.
Gold held out his hand, stopping Emma in her tracks. "Now, now, there's no need to panic. It's simple, really. You're going to go upstairs and rip out Regina's heart and crush it, killing her and the Evil Queen. If you do that, Henry will be fine."
"And if I don't?" Emma asked.
Gold pulled a dagger from his jacket and held it up to Henry's throat. "He dies."
Emma felt a large amount of knots begin to settle in her stomach. This was not good at all. She had to choose between her wife and her son. "You're a sick man."
"I know," Gold said. "Now, take out your heart."
"What?" Emma asked. "Why would I do that?"
"Because I will be controlling you through your heart," Gold said, holding out his hand. "If that makes you feel any better."
"No, it doesn't," Emma said, glaring at him.
Gold shrugged. "No matter. Now give me your heart and let's get on with this. The faster it's over, the quicker we can all grieve and move on."
Henry looked at Emma with a pleading gaze, but Emma shook her head. If Regina woke up and found that Emma had chosen her over Henry, Regina would never talk to Emma again. Much less want to live with her.
Emma reached into her chest and pulled out her heart before reluctantly handing it over to Gold. Gold smiled and commanded through Emma's heart for her to go up to her and Regina's bedroom and kill Regina.
Tears started falling down Emma's cheeks as she climbed the stairs and walked quietly into the bedroom. Regina slept peacefully, not even knowing what was about to happen. Emma hoped with every fiber in her being that Regina would stay asleep.
Emma reached Regina and gently pulled the covers down, giving her easy access to Regina's heart. "I love you," she whispered, before reaching in and pulling out Regina's heart.
Regina gasped and instantly woke up, looking at Emma in confusion and terror. "Emma? What's going on?"
"I'm so sorry," Emma said, breaking down in heavy sobs. "Gold, h-he has my h-h-heart and I have t-to kill y-you."
"Okay," Regina said, lying back onto the bed. "I'm assuming this has something to do with the Queen? And Gold's recently hidden child?"
Emma sniffed and nodded. "I don't want to do this, but he's got my heart and he'll kill Henry if I don't follow his commands."
"Smart move," Regina said bitterly. "Don't worry about it, dear. I'll see you again someday."
"No," Emma said. "I don't want to lose you. I can't lose you."
Gold groaned in frustration and gave Emma's heart a light squeeze before commanding her to follow along with the plan.
But Emma kept resisting. She wanted her wife alive. But then Gold would kill their son, and what was life without Henry?
"Stop fighting it," Regina said gently. "You're hurting yourself for no reason. Just make it as quick and painless as possible."
Emma let out another sob before looking down at Regina's heart in her palm. Regina smiled sadly before grabbing Emma's other hand. Emma glanced at her. "I love you."
"I love you too," Regina said softly. "Now get it over with and save our son."
Emma looked down again at Regina heart before crushing it completely as quickly as she could. Regina's hand in Emma's went limp, and Emma collapsed onto her knees. Her wife was dead. The love of her life was dead.
Henry came running up the stairs, holding Emma's heart. "Gold untied me after he knew that Mom was dead. He gave this to me, which you should definitely put back into your chest before something happens."
Emma took her heart and looking at it thoughtfully. "I can't live without her. There's no point."
Henry's eyes widened. "Wait, what are you-"
Before he could finish his sentence, Emma crushed her heart in her hand, falling to the floor. Henry dropped down beside her, grabbing her hand, hoping to see her heart in it. Not seeing it, he began to cry, holding onto the hands of both of his mothers.
"You forgot something important," Henry whispered to Emma. "You could have split your heart in two."
