Your Pov
Back to the dreamscape >>>>>>
My eyes might as well be a Waterfall because my tears were an endless rush, I turned to Gaster and stood up to embrace him. He loved me, they were my family. Gaster locked away my memories and powers so I could live a normal life, he never actually left me. "Gaster? Is it okay if I call you dad?" I say shyly, I was answered with a chuckle and a tight squeeze. I pull away and smile, wanting to remember it all, even the painful parts. I ask Gaster to unlock my memories and he obeyed my wish, I fell to my knees as the information and memories hit me. Some were sad, loving, painful,scary the list could go on but I was grateful for every good one.
"Okay (Y/n), it's time for you to wake up but don't worry you can call me to your thoughts if you want, who knows I may just plague your life with memes." I Give him a look that says 'hoe don't do it'. "Y u no like memes" I close my eyes ready to wake up. "Oh my god."
BACK INTO THE REAL WORLD>>>>>>
I wake up in an all white room with a bunch of monitors and my hand intertwined with Gsans's skeletal one. My (e/c) eyes tear up again, got dammit I cry so much.
"Yup."
"Omg Dad, too soon."
I giggle out loud which wakes Gsans who shows me a shit eating grin. "Well hello there dove." He says with a sleepy voice, his face turns into one of concern when he see me crying a bit. I wave him off and ask him to sit next to me on the bed. Leaning my head on his shoulder I smell that amazing smell of vanilla, smoke, and leather. "Are you okay?" He asks wrapping an arm around me and giving me a side hug.
"Oh you have a crush on Sansy~"
"Dad!"
"Oh alright I'm gone. Awe you sniff him that's adorable!"
"DADDDDD!"
Gsans brushed some of my (h/c) out of my eyes, my cheeks burned and from my now clear vision I could see Gsans had yellow cheeks which made me laugh.
Timeskip>>>>>>>>>>
I met Alyphs who is a small dinosaur and loved anime, I promised her one day I'd come and watch some with her. Gsans and I left the lab in Hotland, I decided finally I was going to tell Sans everything I know. "Hey, let's go to Waterfall I want to talk to you about some stuff." Gsans nodded to my suggestion and took my hand teleporting us to Waterfall.
When we got there we walked to one of the streams and sat down. I took off my shoes and place my feet in the lukewarm water, Gsans copies me and I laugh.
"Alright dollface what did you want to talk about?"
"Well...Remember when we first came here together and I told you once I found out more about everything I'd tell you, well if you still want to know I can tell you." I move my feet back in forth unsure about how he'll take it all. He nods.
"He doesn't remember a lot of the past when you were kids, before the fusion. Gsans isn't exactly Sans but he has some of the same traits. he has only had dreams of your memories but it never shows your face. So you'll have to explain a bit but I'll fill in what you miss."
"You know that would have been a good thing to know earlier."
"Opps?"
Well this should be fun.
