Chap. 13: Internal Phantoms

Nighmare's POV:

To hear that foul name escape her soft lips caused me to stiffen. Shortly after the name escaped her mouth, I heard a small whimper from the corner, presumably from Horror. Anyone could see the growing concern on (Y/n)'s face as the silence continued to be filled with small whimpers. Murder had woken up to hearing Her name and went straight to Horror to calm him down, the whimpers slowly dying down to silence.

I took a deep breath and let it out in a sigh. "Please... don't refer to her by name. Her name is taboo in the castle." She simply gave a small nod in response. "She is a girl who is utterly obsessed with me to the extent of being a Yandere. She will try to kill anyone who she deems is 'in the way' of her winning my heart... But wait, you had said that you didn't know the identity of your captors......" My eye socket widened in shock as panic overtook over my soul as I mumbled, "She was in the castle.". I started to pace. I didn't know what I would do should She find out that (Y/n) is my soulmate. She would torture her even worse than she had before. She could take her and use her against me. Or, worst of all... She would ki---

My thoughts and pacing came to a sudden halt as (Y/n) wrapped her arms around me from behind in a warm embrace. The static of my magic slowly receded from the air as my nerves had calmed and my extra appendages stopped thrashing about the place. I turned around in her grasp and hugged her in return, holding her firmly in my grasp as I mumbled low enough that she was the only one to hear me. "I don't want to lose you."

(Y/n)'s POV:

Nightmare's arms were trembling as he held me to his chest. The way his voice shook as he mumbled those words sent a spark of compassion into my soul. But I also felt a faint wave of fear, but it wasn't mine. The sudden feel of anxiety shone clearly in his eye, the fear that he might lose me. The look from there, sparked a small memory.

(Flashback...)Young (Y/n)'s POV:

Mommy had her arms around me in a warm hug but I could feel her shaking. Could feel the wetness growing on the top of my head where my hair grew soaked with her tears. She loosened her hold enough to look at my face, her weariness from carrying me and running the entire way here showing on her own face.

"It's okay my sweet angel, we're safe for now. Those bad guys had lost our trail." Mommy's eyes trailed off to behind me, to the Messiah. "And I'm sure that as soon as we get enough funds, the people beyond that wall will have to let us in. Where we'll be safe." Mommy's eyes sparkled with hope as she continued and I smiled. I could see the fear in her eyes. The thoughts in her head. It always did. I looked around and my smile faded into confusion as I asked,

"Mommy. Where is Daddy?" At hearing those words, Mommy broke down, her chest jerking at each of her sobs as they echoed within the empty area around us.

(End of Flashback...)(Y/n)'s POV:

"(Y/n)?" Nightmare's concerned tone snaps me back to reality and I realize that tears are trailing down my cheeks. He had pulled me back onto his lap and was gently combing his phalanges through my (H/c) locks. "(Y/n)? What's wrong? You just suddenly started crying."

I wiped away my tears and shook my head, clearing my thoughts. "No no, I'm fine. I just, had a brief memory cross my thoughts. That's all." I replied, trying to reassure them that I was fine.

Chara tilted their head to the side ever-so-slightly while Cross asked, "What was the memory of?"

I started to fidget slightly on Nightmare's lap, trying to think of a way to cover up what the memory actually was so that they wouldn't worry. I was still trapped in my thoughts when Nightmare grunted and saved me an explanation. "H-how about we co-continue this conversa-sation to-tomor-row. It is ge-getting ra-rather l-late aft-ter all. And Horror a-and Killer should really be mo-moved to beds instead of sleeping o-on the floor."
