W. D. Gaster x Reader

A Past Life: sans

"*so, you found out. everything. everything he's worked so hard to hide and pretend it never even happened. pretend mom never happened, me and Papyrus never happened, the years of neglect and murder and torment never happened. bribing Alphys into silence, asking the King to forget who he was before. but he still hasn't spoken to me and Papyrus since we left. i wouldn't be surprised if he doesn't even remember us." sans sat down beside me.

I was surprised to see sans here. "*i came to give Alphys her lunch, she forgot it and asked me to bring it." I couldn't help but to ask, "How can you even be friends with Alphys if Gaster is bribing her into silence?" He frowned, "*you wouldn't learn this from the tapes, but she visited me and Papyrus all the time. helped us out when i couldn't make ends meet, made sure we were okay, helped when Papyrus got sick or something was going on that i couldn't handle on my own. her and Grillby. she doesn't speak of our past to anyone. i don't mind, i can tell it makes her uncomfortable anyways."

I bit my lip some, "And, what about your mom? Aren't you angry or sad? He could've helped her heal you." sans nodded, "*you're right. and i was angry, and sad, and depressed. but i had to grow up, my feelings were no longer valid, so it all turned to static. my emotions blurred themselves into nothingness. though, slowly but surely, Papyrus brought the joy back into my life." I nodded at this, I can understand that. "And, what about Gaster? Don't you hate him?" sans looked down. "*i've learned that there is one thing much worse than hate in this world. indifference: lack of interest, concern, or sympathy. it is to give absolutely no fucks about something or someone. something good happens, don't care. something bad, still don't care. i feel indifferent towards him, and ya know what? i learned indifference from him."

I frowned as I heard this. I can't believe I'm dating this man. "He knows I'm friends with you. I mentioned you once in front of him and he left the room. He probably feels guilty." sans sighed, but said nothing. "He jumped." I said softly and sans looked up at me, "*what." "Gaster never fell into the CORE. After a while, he went into this downhill spiral and, in the end, he jumped into the CORE." sans looked away, "*honestly, that's what i assumed, but i hoped it wasn't true. Alphys told me when he fell in, just before everyone began to forget who he was. it effected everyone except me, for obvious reasons." I was one of the few who knew the true extent of his powers. "*i would think about it, often. i knew he was too smart to just trip and fall in. i figured he must've jumped, but i hoped he didn't. guess i was right." I didn't expect the news to change anything. I just wanted him to know. Having answers is often better than being left to wonder.

"*Alphys was also the one to tell me when he came back. she said you found an old picture of him, one of the few time forgot to erase, it jogged her memory, she opened the portal, you pulled him out. then the moment he left the Void, everyone remembered everything. except Papyrus, he was too young and never saw much of his own father anyways." I chewed my lip. "Does it, hurt? To be back here?" He shook his head. "*while my dad was gone and before you showed up, i was Alphys' assistant. and as i said, for a while i felt indifferent towards everything, even this, my childhood home. the pain i probably should of felt never came." He took a deep breath. "Do you feel uncomfortable about me dating your dad?" I asked softly. "*no. he isn't exactly a catch, but it isn't like he's trying to replace mom. he's just moving on."

I looked down some. "*hey, don't be so down. come on, how about you call Alphys in here so I can give her, her lunch?" I nodded and I went on the intercom, "Alphys, your lunch has arrived." I left the security booth with him and then went with him into the main room. "*hey, i'm glad we had this talk. you deserve to know what happened, since he is your boyfriend." He said and I heard Alphys gasp, "You told her?!" She said as she entered. "Not exactly, I was watching an old security tape and, I saw it all. sans walked in on me and answered some of my questions. I found out on my own." Alphys accepted her lunch and frowned. "Oh. I'm sorry you had to find out that way. He probably meant to tell you at a certain time."

I shrugged, "I know, and I also know he isn't the same person as he was before. And I still love him." I said as I bit my lip, though the way I felt about him now wasn't that simple. "So, that makes four people who know, everything. You, me, sans, and Gaster." "Make that five." We turned and saw Papyrus had just entered the Lab. sans looked bewildered, "*y-you remember?!" Papyrus looked away and shrugged. "Well, sort of. I remembered bits and pieces, but you butt-dialed me while you were sitting and talking with (Y/N). I heard everything, after a few moments I headed over here. I know I should of hung up, but, I was finally remembering. Bits and pieces grew into moments, I was beginning to make sense of everything, I was learning about who I really was before we went to Snowdin. Though, I didn't know about him, Gaster. I didn't know I had a father, I could hardly remember him at all. Besides a vague image of his face that I hadn't been able to place until now."

sans was tearing up, "*y-you weren't suppose to remember. you shouldn't have to remember that hell." "I can't remember most of it. Only a few moments now, but, most of those moments are of me and you. I don't remember mom, and I don't have much memory of dad. But, even if they are terrible memories, I still wish I could just remember. Maybe if I could, you wouldn't be hurting so much right now. I know you are, don't try to deny it. I know you hurt, I just wish I could share the burden with you and give you someone to talk to." That's so sweet. sans looked down, a few tears fell down his face. I could tell he was in pain. I could tell he was hurt.

"*the whole situation now is still just, shit. complete shit. Gaster, dad, whoever the hell he is. he made amends with everyone when he came back, strived to make up for everything he had done. he made a new life for himself, became the Royal Scientist again, moved back into our old home, became a better scientist, and found a loving relationship with (Y/N). but he's still too ashamed to talk to his own kids. he's still too sorry to step up and finally be a real father." He paused, shaking his head. Another tear rolled down his face as he looked up at us. His eyes were full of the pain and sadness that he's kept locked away for years."*no, no." He muttered, "*my father died with my mother. i'm an orphan, and your Dr. Gaster is a stranger to me." He said, he sounded so hurt and conflicted. But at the same time he sounded like he was dead serious.

I heard yet another voice behind me. It sounded nervous. "Oh." Was all it said.
