So in the geno run you meet Toriel in the ruins and kill her then you go to Snowdin and you see Sans and Papyrus,you break Papyrus' amulet while fighting him for the first time(but you don't kill him yet)and Sans is saved by Alphys one last time and is turn into (Umm...)SansNeoHp!(I'm going to suffer drawing him...-_-U Oh well worth it!)And you will fight him at the judgement hall but before you will first fight Papyrus a second time and kill him at the start of the Waterfalls and fight Undyne at the end of it,after you fight Mettaton and Determined MTT ,Alphys come after and Asgore too...And finally SansNeoHp and you leave the Underground after killing him...

And in the Pacifist run Toriel become your mom but you will leave her(We love you Goat mom!T^T)You will meet Flowey but ignore him when he proposing you to kill everyone and Sans save you from Flowey attacks and Papyrus come just after you thanks(or hug //-w-//)Sans for saving you and you give Papyrus and especially Sans some hope by becoming friends with them then Sans propose you to go to Grillby's or you can eat some spaguetti with Paps (If you go with Sans you will try to do some puns and Sans will become THE pun master or if you go with Paps you will cook with him)whoever you choose you give them even more hopes and Paps will give you the skeleton amulet where Sans's last piece of hope is and you will encounter Undyne and fight her but not killing her and becoming friend with her when you go to her sleep party(??I don't know how we call it in english...xc)where you will also meet Alphys(Next comment XI)

While the sleep party you give Undyne hope and after you go to the lab with Alphys where you tell Alphys to be honest with her feellings for Undyne and give her hopes and meet MTT and fighting him but you don't kill him and giving him hope by telling him that he's a great star and will be an even greater star at the surface after you meet Sans and he ask you why do you want to help monsters and you give the responce(You choose what you wanna say) and he will let you pass if the reason is good and you meet Asgore who will be telling you the story of the monsters and giving him hope by telling him that it will be ok on the surface and then Sans teleport right behind him with all of your friends and you see that he's finally smilling and with hope and he will go to the barrier but he will trapped by Flowey who will take Sans's hope and turn into Asriel and you will have to save him and let him go but he won't turn back into Flowey and die happily..(Next comment -_-"")

Then you will give Sans,who is almost dead,the amulet and he will wake up and break the barrier before falling asleep then Paps will take Sans in his arm and everyone will go out and meet the sun who will wake Sans and will make him cry with joy!And the end!!Yay!!*fall on my bed*I don't feel my left hand anymore...

AND before Sans is trapped by Flowey,Toriel comes back and meet everyone!

That sounds a lot like it's going to be great.

Thank you!!-^^-
