The Monster is You
Sans woke up filled in anger. He was feeling betrayed by everyone. So far, the only people willing to help him had been Riverperson, Grillby, and a few other monsters from the pub. But all the others had condemned them.
He wouldn't take this anymore. If it was war they wanted, then that's what they would get. He was done being peaceful.
-Serifa, wake up.
-Good morning... Slept well, love?
-Get ready, we're leaving. Royal Guards are after you.
-W-What..? Since when...?
-Just get ready. We don't have time.
Serifa could feel something was off. Sans was being way too cold. She knew he could be serious, but this was different. She got ready and went downstairs, where he was waiting.
-Are you...alright?
-Yes.
-You look...different today.
-I'm fine. Are you ready?
-Sans...I'm worried about you...
-You know who you should be worried about? You should be worried about all these people wanting to murder you! But it's okay. As long as I'm here, I'll turn all your enemies into dust.
-What are you saying, Sans...? Are you going to...
-YES, I'M GOING TO KILL THEM! Are you gonna lecture me for that? For wanting to protect you?
-Can't you do that without killing people...?
-NO, SERIFA! I CAN'T!
Sans was getting more and more pissed off.
-There must be another way!
-Don't you get it Serifa? These people won't rest until they kill you! They're evil Serifa! Plain evil! To save you, I need to kill them all! Eradicate them one by one, until no one remains!
-Then...don't do it.
-Don't do what? Don't save you? JUST LET YOU DIE?
-YES! I don't want to sacrifice others like that! I don't wan-
-YOU DON'T APPRECIATE ANYTHING, DO YOU? Sans yelled angrily and slapped her.
They were both surprised. After realising what he did, Sans covered his mouth in shock. Serifa looked into his eyes. That look killed him. It wasn't an angry glare. It was a sad, loving expression. He expected her to run away or even fight back. Instead, she ran to him and hugged him, crying on his chest. He was so shocked he didn't know how to react.
-Sans...please come back... I know this behaviour... Trust me, I do... You're very stressed out, aren't you...? My father...he was the same. He was so worried about me, it ended up destroying him... Sans, my love...you must be in a really dark place right now... But you have to fight it... You have to come back... Don't walk down the same path as my father... Don't lose yourself like he did! I'm right here Sans... Come back to me... Please, come back...come back...
Sans didn't know what to say. Serifa was right -he was losing himself more and more after each reset. He pushed her away from his arms and avoided looking at her.
-I...I'm sorry, Serifa... I...I really didn't want to hurt you...
-Sans... she smiled and approached him again, but he stopped her.
-I don't deserve your love, Serifa. I hit you. You have that habit of loving people who hit you...don't do that, please.
-Sans...you're back.
-Yes...thanks for bringing me back to my senses. But what I said is serious. You shouldn't love people who hit you.
-It's not like that, Sans. I know it all from my father. You're probably going through so much...it stressed you out, didn't it?
-Stop making excuses for people that abuse you, Serifa! I'm serious!
-It's not about excuses, Sans. It's about finding strength in your heart... Strength to forgive and stand beside your loved ones when they need you.
-That mentality kept you imprisoned and abused by your own father for so many years!
-I know...I was wrong back then. My father...had already lost his sanity. There was no helping it. But you, Sans... you're still sane. I feel it Sans! You came back! You aren't sick like him!
-And what if I lose myself again Serifa? What then?
-Then...I'll have to bring you back again, before it's too late!
She approached him once more and hugged him. Sans was melting inside. How could he have hit such an innocent person? Someone who loved and cared about him that much...? He wrapped his arms around her.
-I'm sorry Serifa...I'm so, so sorry... he cried.
-You're back... That matters the most.
A loud knock on the door interrupted them. It was a Royal Guard.
-Sans? Is everything alright? We heard screams and cries...Are you alright, buddy?
-Y-Yes, everything's cool! Why are you here?
-There is a human in your house Sans! We have to capture her!
-Alright, I'll bring her to you!
He opened the window and took Serifa's hand.
-Listen. I can't promise you I won't kill. But I'll only do it if it's necessary. We have no time to discuss it now. Let's get going.
Not sure if he could keep his word, Sans froze time and escaped with Serifa through the window. As usual, they went to Hotland with the Riverperson's help, and continued to the third floor. Serifa had the same conversation with Muffet, becoming friends with her again. Sans tried to persuade Muffet to help them, but she refused for the sake of the rest of the spiders.
-Of course...after all, you still only care about yourself...what nice friend you are! he mumbled to himself, annoyed.
They reached the MTT Resort once more. Like before, Sans let Serifa wait outside and walked in. He soon came back to retrieve her. When they walked in, the place was empty and full of dust. Sans managed to find a good excuse for it. Serifa believed him. The unseen hooded figure didn't.
They walked to the castle again. Serifa, once more, noticed there were no guards.
-That's because everyone is afraid of Asgore. He's a really evil person -he has declared war upon humanity once he gets all the souls he needs. I have to...kill him. It'll be better for everyone.
-If he is that dangerous...maybe it is for the best. Serifa looked down.
Sans felt really ashamed for telling her such a huge lie. But it was for her own good. She wouldn't feel that bad about killing him if she believed he was dangerous. It would just make things easier. Besides, he had already given up on trying to persuade him to spare her.
He walked into the Throne Room with Serifa. He stayed silent -he was too ashamed to face Asgore after all he had done. Without saying anything, he summoned four Gaster Blasters and shot him dead. He quickly ran and took his soul, pushing it into Serifa's body.
-Sans? W-What did you do? It feels...weird.
-I gave you his soul. You need it to cross the Barrier and go back to your world.
-But...it's here that I want to stay...with you...
-You aren't safe here. Don't you want me to have to kill less people?
-Can't you...come with me? Maybe we could make a fresh start!
Sans thought for a second.
-I suppose I could...Give me a sec.
Sans disappeared and reappeared after a while.
-Where did you go?
-To the basement. I took one of the human souls Asgore was keeping there. Now we can both cross the Barrier. Come on...let's go.
They walked to the Barrier. Before crossing, Sans looked back with a sad expression on his face.
-Goodbye, Paps...
After they crossed the Barrier, they ended up in a slope of Mt. Ebott. Sans was amazed by the beauty of the surface. He felt so peaceful just breathing all the clean air and watching the blue sky.
-Serifa...is that the sun?
-Yes, Sans. That's the sun...
-Beautiful...
-Clarisse? I finally found you! an unknown voice was heard from behind them.
Sans hadn't heard that voice before. He turned around and saw a man running towards them. He then heard Serifa's voice, barely able to even speak.
-F...Father...?
This wasn't happening. No way it was happening. Why, of all the people they could meet... Why did it have to be him?
He reached closer.
-Clarisse! I finally found you! I heard people talking about a girl that went towards Mt. Ebott... So, I came to find you!
Sans stood in the middle, protecting Serifa.
-Father... How many times do I have to tell you... Mom is dead... I'm Serifa! I'm not her!
Serifa's voice started cracking. As her father drew closer, Sans summoned his magical bones, getting ready to attack.
-Don't hurt him Sans!
-Seriously? We both know what he did to you! He hurt you!
-He's my father Sans! Whatever he did...I still love him... she cried.
Sans sighed and canceled his attack. Serifa was upset enough already. She didn't need anymore pain.
Serifa's father tried to grab her, but Sans got in the middle, protecting her.
-Clarisse? Who is that? In fact, what is that? That's a monster!
-You got some nerve...calling ME a monster. Sans glared at him.
-I'll save you from that monster Clarisse! I'll save you and take you back to our home!
He pulled out a gun and pointed it to Sans's head. Serifa freaked out.
-Father, no! Listen to me! I'm not Clarisse! Clarisse is my mother! I'm your daughter... I'm Serifa! Remember me father... Please remember me! I'm your daughter! And this person is my boyfriend! Please, please father...don't hurt him! Don't hurt him!
Serifa was crying. Her father lowered his gun in shock.
-This...is your boyfriend, you say? This monster?
-Yes, father... He's-
A gunshot was heard. Serifa's forehead started bleeding as she fell down.
-Insolent woman...HOW DARE YOU CHEAT ON ME?
Sans got infuriated. With a bone attack, he hit the man's arm, disarming him, and quickly grabbed him, throwing him on the ground and beating him with his own hands.
-AFTER ALL YOU DID TO HER! AFTER MAKING HER LIFE HELL! YOU NOW KILL HER! HOW CAN YOU BE CALLED A FATHER? YOU KNOW WHO'S THE MONSTER? THE MONSTER IS YOU AND YOU ALONE!
Sans was shouting in anger. His eyes were teary but he wasn't crying. He was just there, screaming like crazy and punching the man on the face with all hid might. The man was crying in pain, but Sans didn't care.
-YOU DESERVE THIS! DO YOU HEAR ME, YOU IMBECILE? YOU DESERVE THIS!
It didn't take long before Serifa's father died. His face had become disfigured and covered in blood. Without second thought, Sans kicked his body off the mountain's cliff.
-Disgusting human...that's some EXP I'll never regret.
His left eye flashed.
