The Fatal Mistake

I walked around the dark lab for hours my feet where really starting to hurt until I see something with a tarp over it. I got curious going against my better judgement and I run to it, suddenly I feel my body heave forward and I tumble over a wire crashing into the machine covered by the tarp. I looked up in shock as i'm blinded momentarily by a bright white light and then everything returns to normal.... What the hell just happened?! I questioned as I get back up and remove the tarp. It was a Time Machine, I noticed a envelope on the dash of the strange machine and it said To Sans and Papyrus Bones The letter is written in shaken scribbles I grabs the envelope and rip it open the letters fall out, my heart pounding in my chest "THATS DADS WRITING!" I read over the letter as my hands begin to shake violently...

"Dear Sans
Im sorry I wasn't as good of a dad as I could of been, I left you and Paps behind, I'm sorry you two had to suffer so much growing up but I know you two my boys are strong independent boys who don't need parents. Sans You need to Stay Determined, Love your brother with your heart and soul and stay determined. Do not fix that machine, its wrong I want to go back and stop myself from doing the things I have done. its too dangerous to bend time. It was my destiny to die, do not try to bring me back.... the other timelines will scare you... do not.. please dont... fix that machine I love you both so much... i dont want to see you hurt

Dear Papyrus
Make sure your big brother is good to you, i'm sorry I was not a good father. I want you to be strong and keep yourself out of trouble and make your brother smile everyday, he needs you more than anything. Papyrus my boy... there is a orange scarf in my bedroom in a drawer with a lock. the combo is t-i-m-e. Get your brothers help if you cant open it. I love you so much my boy
I love you both XO D.W Gaster"

I drop the paper and fall back one of the G.B's stops be from falling over, My eyes well up with tears. Enough is enough for today.. i-i should go show this to Paps..."

Sans POV
I walk upstairs wobbly and lock the garage behind me quietly, And return into the house. Papyrus was sitting on the couch staring off into the distance looking lost and not happy. "Paps? are you ok?" I asked very concerned. "I... I dont know... but suddenly I felt dizzy... so i sat down then my heart is very heavy and achy.. like something is... missing" Papyrus was no longer himself. "Dad left us a letter when he died" I showed him but then he responds

Who? We have a dad?
