~Fell's POV during the events of Horror and Error~

I huff, walking around Snowdin forest.

It's been hard to go home, hard to walk around Snowdin. Edge was all that protected me from dangerous monsters ganging up on me.

A portal opens in a clearing, catching my attention. I hide behind a tree, cautious fear lighting up my eye without my knowledge. The portal drops a skeleton with a cracked skull before it snaps shut. I slowly walk toward the skeleton, kneeling in front of him. He looks up at me, looking like me, but his red eyelight is unstable, and there is a giant gaping hole in his skull. He is wearing an oversized jacket and a bloodied white shirt, as well as black shorts and some small pink flip-flops. He carries around an axe which is just covered in blood. He lunges at me, and I jump away, fearing the mental state of this skeleton. However, he leaves his axe, wrapping his arms around me, crying into my chest.

How short is this skeleton?

"P-papy is-s g-gone...and-d E-error is-s g-gone...p-please d-don't l-leave." He sounds stunted in terms of mental age and function, barely holding his words together. I slowly hug the small skeleton back, frowning.

What kind of world has he come from?

"I won't leave. Just tell me your name and a little about where you came from, okay?"

"M-my n-name is-s H-hor-rror-r. M-my h-home is-s r-run-nning-g o-out o-of f-food." I slowly nod in response, kneeling down to his level, having to practically sit in the snow.

He's so small. He wouldn't survive here, not for long. His look can only protect him for so long. He'd just be 'Free EXP' to someone.

"My name is Fell. This is my home. We think of the world as Kill or Be Killed." He tilts his head, confusion covering his face.

His world is running out of food? He might think in terms of food.

"Think of it like Eat or Be Eaten. You either eat, or you are eaten right?" Horror nods, the analogy seeming to connect.

"Well, that's kinda like here, but monsters here won't eat you. They'll just kill you. If you have a stronger monster, you can hide with them and remain safe. Or safer than you would normally." Horror nods. I stand up, freezing when he hugs me again.

"C-can I-i s-stay w-with y-you?" I sigh, thinking it over in my head.

He'd be another mouth to feed when I can barely leave my house as it is. But he looks cold, alone, and scared. I don't think this Error fellow is coming back anytime soon.

I look at him, watching as he slowly picks up his axe.

"I-i c-can b-be s-scary!"

He wouldn't survive on his own in this world. Not even with my analogy helping him.

Something steels inside of me, and I smile at Horror, picking his axe up with ease.

"C'mon. I got a warm place to stay."

"I-isn't i-it d-dangerous t-though?"

"Ah, I can protect you. I'm a big strong monster! You won't be hurt. Promise." Horror smiles at me, and he clings to the axe handle, following me.

~Horror's POV during the events of Lust and Error~

This skeleton, Fell, has been very kind. He didn't even notice me slip Papy's dust into the food. I ate Papy. Papy will live in me. He'll make me strong enough to survive in this world. Fell had to dust a few monsters a few days ago when we went to the store. They seemed so worried about what I would do that they didn't even see Fell attack! He's so strong! And with more monster dust, we'll both get stronger!

...

He says this world is "Kill or Be Killed" but eating monster dust is still the way to get stronger.

...

I'm a little worried about Error. He seemed so afraid of whatever was happening when he pushed me through the portal. I wonder where his portal went.

...

Fell sometimes talks about "Alternate Universes", known as AUs...Are we from different AUs?

...

I asked him if we were from different AUs and he said yes. But that doesn't matter. We're all we got right now in a world that wants to hurt us. He's not going to abandon me.

...

He still doesn't know I'm feeding him monster dust. Or maybe he does...? But isn't eating monster dust a bad thing? Error made it seem bad...? Does he not care?

...

He said he knew I was feeding him monster dust, but that he understood why. He had been gaining EXP and LOVE from the dust, gaining more Magic Power too. The dust was making him stronger. So he didn't mind me feeding him dust.

...

He put someone's dust in this time. When I asked him who, he said it was a really strong monster. We both ate from the food he put the dust in, we both checked our stats. We gained HP, LOVE, EXP, and MP (Magic Power). A lot of it. He seemed really happy...I wonder...

...

He confirmed my suspicions happily. It was his Papy's dust. He just wanted to be united with his Papy too! Now we both have our Papys within us! We'll be so strong, all other monsters will cower!

...

I asked him when Error is coming back. He said he doesn't know. Error could have forgotten me. He said that it's not likely for Error to have forgotten me. He told me from how I describe Error, that Error is worried about me, and will be coming to find me soon. He confessed he was scared of being abandoned here. Does...he miss his Papy too?

~Fell's POV during the events of Dream x Error~

Horror is such an inquisitive little guy. He asks me all kinds of questions. I answer every one as truthfully as possible, even the questions I don't really like, or have an answer for.

He reminds me a lot of a younger Paps. Full of so much inquisitive hope and joy for every moment of life. He's been through so much though.

He's grown quite a bit, now able to jump and be as tall as me. Maybe I've been growing too.

He keeps wondering about Error, when Error is coming back, if Error forgot him. I told him what I knew.

"Fell."

"Yeah, Horror?"

"Do you enjoy my company? Or am I too weird? Are you just being nice to me?" I look at Horror, who is holding his moderately better sized axe.

Yeap, he's definitely grown. He's such an oddball. This isn't the first time he's mentioned thoughts mirroring anxiety and depression. It's just the first time he's been direct about it.

"Hm, let's go question by question, okay?" Horror nods, sitting on the couch beside me.

I have found that when he asks multiple questions, he finds it clear to go question by question.

"Question one: 'Do I enjoy your company?' Well, yes. Otherwise I would have sent you away by now, or tried to dust you. Question two: 'Or are you too weird?' Horror, dear. We kill monsters and eat their dust. We, not just you. We're both weird. But it's okay. Question three: 'Am I just being nice to you?' Okay. Yes, I am being nice, but in this world, monsters usually aren't nice. Hell, even my own bro, who I raised, became mean and aggressive." Horror furrows his brow.

"So in summary?" I smile at him, nodding.

"Question one: Yes. Question two: We're both weird. Question three: Yes, I'm being nice, no it's not the way you think." Horror nods, smiling happily.

"Thank you, Fell!" He runs off to the kitchen, and I sigh softly.

What will happen when Error comes back?

A portal opens in the living room, Horror running out of the kitchen, and hugging the tall skeleton who walks through. He looks like he's been through hell, covered in all kinds of scars and bruises. His blue hoodie and red shirt are a little torn. His shorts didn't fare much better, his flip flops looking soaked to their core. He has blue tear-tracks running down his cheeks, and he also looks like he's been crying recently. He has a few black error signs covering his eyes, but his mismatched colored eyelights shine through, smiling at Horror.

"H-h3Y bUdD-dY, h0W h-H45 f-F311 7-7r3473D y-y0U?" Horror beams a massive smile at his falling apart friend.

"Fell has treated me so well! He understands me, and accepts all my quirks!"

"G-g14D 7-70 h-H34r !-!7. !-!'M g-G-g0Nn4 G-g0 70 B-b3D, k-K4y?" With that, Error falls forward, into a state of unconsciousness. I rush forward, catching the broken skeleton. I slowly lay him on the couch, sitting at the dining table with Horror.

~Error's POV (Finally, right?)~

I slowly blink awake, looking around.

"Wh47 H4pP3n3D?"

"You fell through a portal, looking like you just got defiled. Also, I've been taking care of Horror while you were otherwise engaged. He's talked a lot about you."

"g00D 7h!Ng5 ! H0p3."

"Yeah, all good." I nod slowly. Fell sighs, kneeling beside me. I try to move away from him. He doesn't lean close or try to touch me.

"I know you've been through some shit. I promise to try to protect you, okay? I've gotten pretty strong recently."

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

~Fell's POV (That didn't last long)~

I sigh.

I get why Horror was so concerned about Error. He's seen a lot of shit...

I walk to my room, sitting on my bed.

I will kill whoever I have to, to protect Error from the world. I won't let anyone take him.
