A/n: please work with it and enjoy
(×_×) I noticed I accidentally messed up on the other chapter hope I don't do the same with this oneWaking up before dawn you stand up and decide to change out of the dress/suit. You look in the closet and take out one of sans' sweater and lazily let it on along with your normal jeans and beanie. You kiss sans' cheek and walk out of the room silently shutting the door. Checking up on papyrus you see him soundly sleeping in his bed. You silently close the door and walk down the stairs. You go on your knees and stick your arm under the couch. You bring out a box of cigarettes and a lighter. "I don't...I don't think he'll care would he? No...no he won't..." You stand up and shove them in your pocket and walk out. Walking as far away as you could you stop near an edge. You sit down and stare at the water flow. You take out the cigarettes and take one and the lighter. You light it up and let out a puff. Looking besides you, you saw a person. Well not a human but just a black blob in the shape of a male human that just sat beside you. Just breathing, no sign of being alive except for breathing. Youve seen this thing before but just never mentioned it so you wouldnt have neen a bother. You talk to this thing as if it is physically there always waiting. Letting out another puff you take it out. "Im afraid...im afraid that i might get them into trouble or even hurt one of them and it would kill me if i hurt my now husband. Just imagine being killed by your own lover. Being it felt like getting stung by millions of bees right? Or even worse for all i knew" shaking your head you smoke the cigarette and let out another puff. "What if i hurt frisk,...toriel....metteton...alphys....undyne....maybe even the great asgore oh hiw terrible thatd be...why am i even talking about this?" for the first time that you ever witnessed that the blob moved. It crawled towards you and lazily wrapped its arms around you. You didnt get scared or anything your eyes just watered and you hugged them back letting a few tears fall and squishing the cigarette with your hand leaving a small burned marking. Suddenly the human blob disappears but leaves small light smudges on the sweater. You let out a sigh and gently place your hand on the snow so it wouldn't sting that much. Standing up you make your way to grillbys and push the door. It opened very slowly for some reason. You didn't question it but went inside. Grillby was washing a cup like he always is. He looks at you and you give a friendly smile. You sit on one of stools and ask for a burger which in a few minutes was given to you. You ate it silently along with the fries. Standing up you leave money along with a 10$ tip next to the plate and walk out. You make your way back home and walk up stairs. You walk into sans' room and lay next to him. "I want to...but I don't think he'll like that he'll get worried and chase after me...but what if I risk it and go anyway...what if I can't come back..." You where in deep thought but you began to get tired. "No...I'll go any way...if one was able to come to this time line then imagine the other... I'm sorry" you kiss sans' forehead and stand up again. You write a note and put it beside him. You grab your back pack and Putin over your shoulder. One the way you don't a box that had gloves that had claws at the knuckles. "This might be helpful" you take it off and put it in the bag. You make your way to alphys' laboratory and go in silently. You find your way around to a portal on the ground glowing a neon blue. You slowly let you self fall. It felt cool and breezy, as if a cold day in winter with out snow. It suddenly stops and you where thrown out. You look around and see that your in a laboratory that looked like the other one "this must be another time line...ALPHYS!!" you yell. You did get a response which saddened you but confirmed your thought. Walking down the same hallway you find your way to the exit. Letting out a sigh you open it. As always it was hot out side. Your guessing that your mission is to get rid of chara and the other you.
Why not a time skip
You make your way to grillbys, not seeing many monsters worried you a lot. Well, it hurt more than worried. Opening the door you let out a small breath of air. No body was in here, just grillby. He didn't have much of a face and even you could see the pain on his supposedly glasses(face??). You came and sat on one of the stools and just gave small glances at grillby. He didn't wave, he didn't clean a glass he didn't do any thing but just sta d there cleaning one glass when usually he would already give you your order and at least some greetings. You weren't even the cause of deaths and you still felt guilty. Sitting there silently you finally get the courage to speak and just say a simple "I'm not them you know..." Frilly looked up at you and then back down not Believing you in the slightest. Sans comes in not noticing you and plops down a few seats beside you. You didn't even say a word, you barely notice the big gash across his chest. Sans finally notices your presence and both of you finally tense up "why won't you leave us alone!" He yelled. He grabbed the glass grillby held and through it at you, dodging it in time you get little shards from the impact on the wall. His eye began glowing again terrifying you. Grillby hopped over the counter and held sans shoulders. Sans got teary eyed and hugged frilly tightly as grillby held him lightly making sure he didn't hurt anything. You got a little frightened and ran out of the restaurant, "I have to get rid of them.." you we surprised he didn't notice you wearing his jacket. What you didn't notice is that he followed you and planed on getting rid of you instead of chara. You began running out of snowdin and into the ruins, trying to look for them. You hear foot steps behind you knowing it was sans you ran. "Sans! I know you're following me and it wasn't me that hurt all the monsters it was the other me! They did this! They hurt you..." Sans appears out of the shadows and glares at you darkly. Preparing a gaster blaster win his eye shining bright you immediately start talking. Though other knew you where stronger than sans you didn't and you were scared to the point shit was gonna come flying outta yo ass. "How can I trust you, how can you prove to me that you are not the human that killed most of the population of monsters" sans said. "I'm married to you dammit! Not only that how else could i have gotten your jacket!? These humans you speak of I am going to get rid of I promise just trust me this once! And...and if you don't trust me then shoot..." You get down and wait, since what you suspected was that he hated even you to the point he will do what he could to get rid of you. Not feeling anything you look at him and see he put it away. Smiling at him he holds out a hand to help you stand up. You do so and hug him "I know you hate 'me' so much and I'm happy that you somehow find it in your gut to trust me" he somehow felt the good in you that even your hugs made him feel fluffy. He hugged back and smiled again, a genuine smile that he feels he lost after the passing of papyrus and all his loving friends. You continue your way down and go to the home of Toriel. It pained you not to see her there smiling like she always would. Making your way down to charas room you see her sleeping soundly............or so you thought........once you decide to grab their hair they grab your arm and stab it. Yelling a cuss words you grab them and throw them to the wall. Sans immediately gets out a gaster blaster ready to shoot them. You walk up to the and once again grab their hair and grab the knife from their hand and point it at their neck. "Where. Is. (y/n)" your eyes began to glow baby bright blue but you could still see the pupils. "They knew you where coming after them Southey left the ruins" chara said with a smirk. You pull on their hair harder and they let out a scream "fine I'll tell you just let go of my hair!" Letting them fall to the floor you just continue to glare at them silently. "They're at the undyns house, they thought that would be the last place you would check and that you would ignore me and they decided to use me as a decoy because they thought you would easily get rid of me or that I would kill you since they predicted that you would come alone" rolling your eyes you kick their face and walk of leaving at least a few medical things so they wouldn't take to much damage from it. Sans followed after you not looking back but still had a smile. " charas lucky I'm from the good side unless I would've killed them..." Holding out a hand you decided to hold his. He had a light blush on his cheeks and he looked away "why are you blushing?" You say with a laugh in your tone "well uh you're holding my hand" "sans we're married one the other side remember?" "Yeah..." You began to run faster "shut I just realized that if they used chara as a decoy then that means they're planning something big! Ugh we might not have that much time" getting out of the ruins and running across the stands and puzzles you make it to the tiny town. Finding the river you see the man in a hood and jump on the boat "to uh....you know where undyns house is at?" The hooded figure nods and begins rowing. Sans tried running near the boat and held out a hand you grab it and pull him in while the boat was moving. After a few short seconds you where at your destination. Getting off you smiled at them "thank you" sans followed you down "so, now what" he asks. Once the hooded figure rowed away you finally begin to run to undynes house. "Since papyrus was killed and undyne was never splashed with water then the house should still be intact" running in you barge the door open "where are you!" You yell. You knew it was useless but you still did it. You go ever where from the closets to under the couch. Then suddenly realization came back to you "they're not here....they knew I would come here since chara told me and decided to use this as another trap...they're doing something with the portal god dammit I should have known!!" Grabbing sans you where gonna run back to the river until he pulled you back. "I know a short cut" he said with a proudly. You smile and he leads you to the left, once you blink you where already there. Kissing his cheek you run inside as you brought out your sword. "They must be at the portal...or at least near it" You thought to yourself. Sans made his way near you and you immediately turned to face him, "sans please wait out side" "no I'm going to help you" smiling warily you let out shakey breaths "please?" Your voice cracks slightly. Sans looked down and sighed "fine...please come out safe" nodding he goes out side. "Finally, I was hoping you'd finally kick the mistake outside" hearing that voice you look up to see them standing there with a wide grin on their face. Going at them you use your sword to try to cut their arm or at least make a gash or a cut trying. They move out of the way and grabs your jacket and pulls you back and throwing you to the wall. Your tattoos began to glow along with your eyes again. "I would prefer you not do that it makes me feel disgusted or even be you for that matter" running again you felt alot more stealth. They tried stabbing you but you moved out of the way and dug your nails into their back making them let out a small yelp of pain. Tackling them down you straddle them, your hands then begun to glow letting out loud zipping sounds. 'You' smiled as 'you' lay there "are you really going to kill me? Could you even do it for the little tantrum you're having?" 'You' said with a smug smile. Your eyes glow brighter, holding their arms down you somehow let 60+ bolts into their body basically cooking them from the inside, tears fell as you did this "I swear to god if this wasn't instant then I would be happy to have made it longer". You stand up and make your way to sans "I'm sorry but I have to leave and.....but.....here. have this," you give him a light but faded pink glowing ball. "It'll help just eat it" sans looks at you and then back at the the pink orb "trust me" he swallows it "close your eyes and count to twenty if you can't ten is plenty trust me baby you'll be happy open 1. 2. 3" sans opens his eyes and sees papyrus, Toriel, alphys, undyne, and all his other monster friends. "I want you to be happy...good bye" you kiss his cheek and run into the portal taking you back to your timeline
