(Frisk's P.O.V.)

The rest of the day's normal. It has definitely been an interesting weekend. I really don't want to go back to school tomorrow.

Mum, Asgore, Undyne and Alphys have all gone to bed. Sans, Papyrus, Flowey and me are the only ones left. I'm glad about that as there's a question I want to ask that I couldn't with the others around.

'Sans, if you're a werewolf, that means you must have been bitten. When was it? And what happened?'

Sans sighs before beginning the story.

'me and papyrus weren't born like most people. we were created by the old royal scientist before alphys. he raised us like we were his sons.'

'BUT, IN REALITY, WE WERE A LOT CLOSER THAN THAT!' Papyrus adds. 'WE WERE CREATED FROM PARTS OF HIS BRAIN SO, WE'RE TECHNICALLY PARTS OF THE SAME PERSON.'

'because he was the royal scientist, we lived in the labs. we'd sometimes help him out with experiments when we weren't at school.

'i remember the night it happened like it was yesterday. papyrus had gotten into a bit of trouble at school. he'd set fire to the kitchen during catering class so the doc had to go with him to a meeting with the headteacher. i was left alone. i was reading in the lab when there was thudding on the lab door. me, being the naïve little 12-year-old i was, thought there was just someone knocking at the door. i opened it and there it stood. the werewolf. immediately, it pounced on top of me, attacking me with, to start, only its brute strength and claws. i tried to fight back but that just made it angrier. that's when it...it...'

He pulls off his hoodie and holds out his right arm to us. His radius and ulna on his arm have marks covering it. Teeth marks.

'why do you think i always wear my hoodie?' Sans says.

'WAIT, WHEN WE WERE YOUNGER, YOU WERE RIGHT HANDED, BUT THEN, ONE DAY, YOU STARTED USING YOUR LEFT EVEN THOUGH IT WASN'T YOUR DOMINANT,' Papyrus says.

'yeah,' Sans says. 'that was because my right was too painful to use. now, it's just force of habit and i'm ambidextrous.'

'Why don't you just heal the bite mark? That's what any sane person would do,' Flowey says.

'this is healed,' Sans replies. 'when your bitten by a werewolf, the bite that infects you stays forever. no amount of healing can change it. anyway, i'll continue with the story.

'the werewolf kept attacking and i was unable to keep fighting, i wasn't strong enough. i called for help, but nobody came. i knew i was close to death, then the werewolf stopped. it howled before running from the lab, leaving me collapsed on the ground, blood pouring from my wounds. because of this, i have no idea who it was.'

'That's another thing I've always wondered,' I say. 'Why do you bleed? None of the other monsters do. And you don't have a circulatory system because you're a skeleton, it doesn't make any sense. Why?'

'to tell ya the truth, kid, i have no idea,' Sans says. 'i just do.'

'Also,' Flowey says, 'you have 1 HP, how did you survive a werewolf attack?!'

'it was the attack that caused my HP to be so low,' Sans says. 'before, i had the average HP of a monster at that age. as i was saying...

'i was lead on the ground, blood pouring from my wounds. the thing is, at that point, i didn't actually know that the thing that had attacked me was a werewolf. i didn't want pap and the doc to worry about me. even though i'm not the best healer, i did my best to heal my wounds. all except the bite disappeared, which confused my 12-year-old self, who just threw a bandage on it. i threw out the destroyed clothes and put on fresh ones and mopped up the blood. by the time pap and the doc came back, it looked as if nothing had happened. it wasn't until the next month that i realised what had truly happened that night.'

The four of us are silent for a few seconds after Sans finishes. I'm about to say something when he stands.

'i'm going to bed,' he says. 'i'll see you guys in the morning.'

He disappears upstairs, leaving us there, taking in the story.
