"I know none of this makes sense," Elsa tells you. "But please, let me explain."
You take a few moments to catch your breath before nodding. Your thoughts still roiling chaotically.
"Okay then. What do you remember?"
"I remember everything now," you reply. I can remember an entire life that I never lived. I remember everything up until..."
"Up until you died," she finishes. "I know this is hard. It hurts just thinking about it. I can't imagine how it must feel to literally relive that experience. But you need to know what happened next, so I'll tell you..."
...
Elsa held tightly onto your dead body, weeping tears that froze before they hit the ground. Frost began to spread across your body as it finally began cooling down, far too late to be any good. This was the chill of death, and never in her life had Elsa felt the cold the way she did now. It was dark and empty, and all she wanted to do was curl into a ball and forget everything.
Anna and Kristoff ran into the gardens, spotting Elsa cradling your corpse in her arms, charred and frozen corpses all around her. "Elsa, the soldiers are everywhere!" Anna told her urgently. "We need to get out of here!"
"No." Elsa let go of your body, rising to her feet. "They killed him. They killed (Y/N). They are going to pay for taking him from me." Frigid energy began to swirl around her, a truly icy glint entering her eye. "They are going to pay."
When Anna realized what Elsa was talking about she jumped in front of her sister, holding her hands out.
"Get out of the way Anna!" Elsa exclaimed, holding back the angry tears brimming in her eyes.
"No," Anna answered, defiant. "Elsa, you can't do this. Not like this. Fighting to protect yourself is one thing. Revenge, murder, that is something else entirely. You can't let your grief make you do something you'll regret."
"I doubt I would regret this," Elsa growled, attempting to push past her sister.
"You would," Anna insisted, shifting to stand directly in from of Elsa again. "It would eat away at you. Elsa, we have to go. You can't do this. We have to regroup. The soldiers already have control of the kingdom. We need to come up with a plan, SOMETHING. Just not this."
Elsa was stiff with rage, and at first it seemed like she would ignore Anna's words, but after several moments her muscles relaxed and she began to weep again, her emotions spilling out of her. Anna ran forward and gripped her sister in a tight hug, Elsa hugging her back.
"Girls, I hate to break up this moment, and I know emotions are high right now, but we really need to go," Kristoff reminded them.
"Of course," Elsa replied, stepping out of the embrace and wiping her eyes. Lets go. I'll lead and make sure our path stays clear."
"Where are we going?" Anna asked. "The whole city is under their control!"
"Then we go to the nearest allies available," Elsa replied. "We need to reach the trolls as soon as possible."
...
They found Olaf and Sven and fled out of the palace and out over the fjord, Elsa creating a pathway of ice across the water with every step. She had much finer control of her powers than she had the last time she had done this, and so the pathway was narrower, allowing the five of them to run across it safely, but as soldiers attempted to follow them the section they stepped on collapsed, sending them tumbling into the water. Once out away from the city they then made for the home of the trolls as quickly as they could. If "King" Hans had any knowledge of the trolls he would do his best to make sure they were found, and they couldn't let that happen.
When they reached the circle of stones they found Pabbie and the trolls already waiting for them. "Pabbie!" Anna exclaimed, rushing to the old troll. "Hans invaded Arendelle with this army and took over the city and-"
"I know, Anna," Pabbie stated, cutting her off and laying a reasurring hand in her arm. He turned to Elsa, his face shadowed with regret. "I also know about (Y/N)."
"How do you know?"
"I sensed something was wrong and used my powers to watch Arendelle from afar," Pabbie answered. "The entirety of yor kingdom has been subdued, what little forces you possessed killed or imprisoned. But dear Elsa, I want you to know that there is still hope, for both your kingdom and your love."
"What are you talking about?" Elsa asked, anger rising in her voice. "(Y/N) is dead!"
"One of him," Pabbie responded cryptically.
"What?"
"(Y/N) is a Split Soul," Pabbie stated. "His soul is split between two universes, two different earths, the exact same man living two completely different lives. Neither one complete, as he is missing half of who he is. After losing the memory of his own life, memories from his other life began to bleed through. That was what alerted me to the possibility. When I felt his death, and the unique manner of it, I knew for certain that I was correct. Now that one of his lives has ended, the two halves of his being can be reuinited.
"What does that mean?" Anna asked.
"And how does that help us bring him back?" Elsa added.
"You bonded with him," Pabbie told Elsa. "Your soul connected with his. Using that connection, as well as your inherit power, you can create a portal that will bring you to him."
"But how does this help us save Arendelle?" Kristoff asked, Sven nodding agreement.
Pabbie shook his head. "Think, Kristoff. Not one but two powerful wielders of magic, bonded together. Their combined power will be more than enough to save Arendelle."
"Alright then," Elsa stated firmly. "Let's do it. Let's bring back (Y/N)."
...
"So... You did all that to be with me again?" You can hardly believe her story, despite the fact that you can feel its truth.
"And to save the kingdom," she reminds you, though she smiles at you lovingly. "But yes, to be with you again."
"Wow."
She straightens her shoulders, determined despite her obvious hesitation. "(Y/N), I have a question to ask you. (Y/N), I love you more than anyone else in the world. I can't imagine losing you again. Will you help me reclaim my kingdom, and when that is done, would you marry me?"
You can't contain yourself as you rush forward and kiss her. You kiss the woman that your heart yearns for, and she kisses you back. "Yes!" you whisper through the kiss. "Yes!"
