First, you let go. A long chat with grabbed clothing won’t be comfortable for either of you.

Second, you imagined your interface changing into the ‘Shop Screen’.

But this time, you won’t be shopping for anything. It had a double purpose as a multiple choice dialogue section. Much like those visual novel investigative games you’ve been playing on an emulator.

There was only one question available in your head so far. You chose that.

> Who are you?

“…I am Sans Serif, Seer and Tactician. ‘Sans’ alone is not my full name.”

He flashed a weak smirk at your surprise.

“Only three others know the truth: Gerson, Grillby, and Asgore. I’d add my mentor on the list… but he’s long gone.”

You wanted to ask how much they know.
But, you realised that you only have three questions. You’ve already used one.

You feel like a shaken soda bottle, trying hard to not explode from the inside.

“Heh, that expression on your face. You wanted to know more, right? Well, kid. I did say I’ll do my best to answer. Don’t worry, I won’t cheat you.”

Soft wisps of blue rose from his blue left eye. Unlike the other times when you witnessed this display, this had no sense of threat.

He’s just showing you his true self.

“Where do we start…?”

“Asgore is too kind and soft to lead a proper war, so someone else had to do the commanding. The first candidate was my mentor, but he declined. He’s more of a tech and science guy. More suitable for support.”

“So he made an agreement with the King. In return for staying in R&D, my mentor will train up an ideal candidate. That person… would be me: a Seer trained to think, act, and fight like a genuine human. Including the swift, unfair brutality.”

“Or so that was the plan. The ideal is always too good to be true, right? I… fell far below standards. Let’s just say, I don’t care about the nation’s fate.”

“I rather choose a peaceful imprisonment. That’s not a good outlook for someone who’s supposed to lead the charge.”

“Think about it for a moment. Can you imagine the Dog Clan members slicing through someone else’s parent? Or Onion-san pulling battleships into their watery grave, drowning hundreds of crew members?”

“Do you think they can do that?”

You… shook your head.

“I had thought of the same. Those who had never seen the War will not realise the horrors lurking behind their dreams.”

Sans stopped his explanation there. He’s waiting for you to start a new question.
You noticed that he did not explain anything about a ‘Seer’.

You had a feeling it’s related to Papyrus.

> Papyrus and his eye.

What’s the deal with that?

If you could quantify the amount of silent dots on the screen, it would have filled an entire dialogue box.

Or two.

“Skeletons… are not usually born. We’re enchantment based monsters. Get a bone -- any bone -- and add magic. Then you’d have a young adult skeleton. During the War, my kind would engineer more of themselves from human corpses. Think of them as Pseudo-Boss Monsters to boost the Royal Guard. They’re supposed to be tough. Maybe tougher than Gerson. In the end, though, they were just as vulnerable to human violence as everyone else. ”

“Papyrus and I defy that convention. Those who were ‘born’ instead of ‘made’ are blessed with the ‘Seer’s Eye’. If you ask me, it’s more of a curse. What does it do? It allows these special baby bones to peer into space-time. How much? It depends on their potency.”

“At its weakest level, it grants the bearer some level of precognition. Anticipate the next move and act on it. You noticed that Papyrus and I are excellent dodgers, right?”

“At its strongest level… you get limited space-time manipulation. Observe timelines. Teleport. See and use ‘shortcuts’. Skew perspective. All those fancy things.”

You wanted to ask Sans how many past and future timelines he had seen, remembered, but that was a question… You only had one left.

It frustrated you more than expected.

Again, he caught on. This time it amused Sans enough to grant you a wink.

“I know what you’re thinking, Frisk. You want to know if I retained any memories from a reset. The answer is no: to witness visions of a timeline is a manual process. A rather exhausting one at that. I get the ‘deja vu’, but to know what exactly happened? I’d need to skim through each event.”

“Trying to gather all the information is a mind-breaking process. Plus, it's a literal maze. Over time, I learned to pick and choose. For example: the number of times you died in my hands, without the knowledge of our friendship. Kept me sane, you know.”

You nodded in agreement.

“…Before I called for you, I checked Papyrus’ fate in the other timelines. Visiting Toriel. Playing mascot for the Royal Guard. Talent Agent for Mettaton. Crowned King. Heh, that’s the only time I did my job as an advisor.”

“The alternate scenarios confirmed my worst fears: the electric puzzle incident broke his seal.”

What?
Seal?
Papyrus was sealed?!

You pressed that question faster than you can think it through.

> What do you mean by a ‘seal’?

Sans had expected it.
Rather, he steered the entire conversation to this confession.

“Papyrus is my life. He’s the sole reason why I wasn’t completely cold. He… he gave me a reason to care. You can say he’s my ‘soul’.”

“Before my parents passed away, they told me that he’s going to be super powerful. Maybe stronger than me. My mentor already had plans for him.”

“I got really nervous. But, I reasoned that they can care for Papyrus. Like how they had cared for me.”

“…Then they’re gone. I became outright terrified.”

“I didn’t want Papyrus to undergo the same training as I did. I wanted him to live a normal monster life. To remain innocent, merciful, quirky, silly… everything that I was denied of.”

“So I stole an ancient magic textbook from my mentor. Then used my genius to seal Papyrus’ Eye. It’s supposed to be a life-long secret. By theory. But… as you can see, Papyrus eventually become too strong for it.”

“That’s why I couldn’t let anyone separate us. Imagine what would happen if his powers went haywire on an unsuspecting family? He could hurt himself. Or worse.”

You asked Sans why did such magic exist in the first place? Was it created by humans?

You know you had passed the three question limit, but you needed answers.

To your fortune, he didn’t hold your cheating against you.

“Those who’re born with a Seer’s Eye bear the burden of ‘True History’. The sealing procedure was for those who had gone weary and wanted to live a normal life.”

“That will only work up to a certain level though. I’m way past the point of no return. As you can see, Papyrus had crossed that border too.”

True History…?

“Heh, don’t you think it’s a bit convenient that humans won the war? Think about it. Monsters could easily band together to rain utter destruction on entire cities. There was no real need to fight head on and suffer losses… Yet, that didn’t happen. Why?”

Because the King and Queen thought it’s too cruel…?

Sans chuckled a bit. “Hey, hey, they’re not the only monster monarchs. What about the other nations? They’re not all nice.”

You don’t like where this is going…

“I can read it on your face. That expression… tells me you just realized that the powerhouses ‘mysteriously disappeared’. You are correct.”

“The humans had the ‘ultimate weapon’: a time-travelling assassin. Immortal, too. All they needed was DETERMINATION. Reload that SAVE enough times, and even the toughest magic becomes predictable. You’ve experienced it first hand.”

Someone had the same powers all those years ago.
Instead of using it for peace, they used it for murder.

No, it was murder done in the name of peace.

You agreed with Sans that it was a grim revelation. Will Papyrus know that right away?

“…I have no idea. That’s why it’s frightening. What would his Eye see? How will it process information? How will he react to it? Will it change him for better or for worse? Will he lose his innocence?”

The thought alone triggered blue, glowing tears.

“I want Papyrus to remain what you call a ‘cinnamon roll’ forever: sweet and precious. He’s winning over the hearts of jaded folk like Cenna. It’s downright magical whenever that happens.”

“I can’t bear to lose that. If Papyrus became Sans Number Two, that will be my last straw. I know it.”

You told Sans that it will be all okay.
Papyrus is Papyrus. He has a unique perception on things.

Trust him.

“…Haha… I’m being schooled in the lesson of trust by a human. That’s some crazy role-reversal there. Humans were defined by a host of negative traits, mistrust was one of them. Here you are, showing the opposite.”

Sans’ smile was weak.

“If… if anything goes wrong and you need to RESET, address me by my full name. I’ll understand.”

Any positivity evaporated faster than boiling water.

“Actually. Don’t. I’d fall into the temptation of keeping Papyrus locked in a time loop forever. I am trained to think as a human after all. Being selfish is a very ‘human’ thing to do.”

“I’m a terrible brother.”

You told him he’s an awesome brother.
It’s clear that he put so much effort to protect Papyrus.
There’s nothing to condemn about that.

Unfortunately, your pep talk was not enough to lighten him up.

“…There’s a fine line between a fort and a gilded prison. In a way, I kept Papyrus in his personal ‘Underground’.”

“Did you know The Underground was the lesser of two evils? The Seers infiltrated human society and founded the Magus Association. Skeletons have a lot in common with humans in terms of physiology. With sensible clothing and masks, they blended in just fine.”

You dropped your jaw.
They had gone into enemy territory and taught humans magic?!

Why???

“Simple: to give them an alternative other than mass genocide. It’s our last resort for survival. I don’t think most of Monsterkind will understand though. We’d be seen as traitors.”

“So, the Seers swore to secrecy. Took that knowledge to their graves. Being a Seer myself, I share that burden. I’m uncertain if Papyrus can carry that weight.”

You encouraged Sans to break Papyrus’ ‘Barrier’.

The eye seal was on the verge of falling apart, right?
Instead of trying to suppress it, maybe it’s time to lead and educate.
It’s better than letting the cinnamon roll fumble in the dark.

The singular blue eye flared from sheer fear. You wondered if you had offended him.

But then… the wisp died back down.

“You’re right, Frisk. There’s no turning back now. It’s time for me to put on the teacher’s mantle again. For Papyrus. Thank you.”

“Why not stand at the foot of the bed for a once-in-a-lifetime spectacle?”

You weren’t sure if he’s making a pun or not.
Nonetheless, you did as you were told.

Sans’s eye burned bright, channeling the magic for the job. He stretched his hand over Papyrus’ right eye. Doing so revealed a hidden lens made out of magic. It was white. And cracked.

The way it covered that eye reminded you of Undyne’s eyepatch.

He started to speak in a strange, cryptic language. It was the same one as Papyrus rambled earlier.

Those skeletal hands kept making signs. You presumed that they corresponded to his speech.

You had a brief flashback of meeting a skeleton taller than Papyrus. That particular reset had gone screwy.

He was in a dapper tuxedo.
His sockets were in the shape of crescent moons. And he had ridges in his skull.
Spoke in the language of hands, just like Sans right now.

Could that mysterious skeleton be Sans’ mentor?

‘Beware of the man who speaks in hands,’ the riverperson warned.

Great, now you have two guys who speak in hands. With a possible third. You wonder which was the dangerous one.

Or…
Did he warn about the Seers in general?

You shoved the speculations aside. They were a distraction.

Papyrus’ sealing lens flaked off piece by piece. They floated upwards into the air before vanishing forever. It reminded you of autumn leaves floating in the wind.

You expected some kind of bombastic light-play. With glass-cracking sound effects to finish off the ritual.

Instead, it happened in sombre silence.

The chanting continued until the last piece was no more. Upon that instant, there was an orange glow underneath Papyrus’ eyelid.

“It’s done.” Sans breathed out a long, exhausted sigh. He had a long day.

You checked the time. It’s not four in the morning. You told Sans that Papyrus wouldn’t wake up until then.

“…Nah. You’ll see.”

Right after he said that, Papyrus’ face began to contort. He struggled with something, even with the medicine still coursing in his bones.

Papyrus opened his eyes. Orange wisps danced from his right socket, free.

“…W…what… what happened?” He asked.

You couldn’t believe it. Papyrus was talking in the capacity of a normal person. It shouldn’t be possible.

When your tall skeleton friend turned towards his brother, his eyes widened in horror. He kept running his mittened hand in a diagonal fashion. On Sans’ chest.

“Oh… oh my god… Sans… are you… are you bleeding…? Is… that …a gash…? Wait… monsters don’t… ketchup?”

The rest of his panicky statements were in a slurry mess.

Sans tucked his brother back to bed. “Hey bro, I’m okay. It’s all a dream. Go back to sleep.”

Papyrus muttered more gibberish before he drifted back to dreamland. The sedatives won this fight.

It doesn’t look good. You asked Sans how you should update your Mom. You got a promise to keep, but…

“Tell her he’s fine. Just. I’ll explain the rest.”

You asked Sans if he’s sure.

“…No, I’m not sure. From the looks of it, Papyrus won’t be able to control his Eye for a while. He’s going to see Toriel’s death soon. Or more.”

You gave Sans the same advice as you had given to Alphys: tell the truth. Time travel is real!

“I tried that before,” said Sans. “Everyone thought I’m nuts. Or pulling their leg. Time shenanigans are not as observable as a botched experiment.”

Good point.

“I guess you have to tell Toriel that Papyrus will suffer hallucinations for the next week or two. By technicality, it’s true. Let’s see how it goes from there.”

There was not much choice. You knew that Mom won’t be able to sleep. She’d keep waiting on the phone for a sliver of news.

You took out your phone and typed the update as suggested. You then pressed ‘send’.

Knowing your sweet friend would wake up to a world of horrors didn’t fill you with determination. Not at all.
