"Human!! I forgive you! Mwah ha ha! You can be a good person if you just believe!" Blue said. The human killed him.

Papyrus was sleeping and didn't know about his brother's death. He's nightmares was of a normal Underfell timeline. He always wondered why Sans was so famous in the human world.

He just waited for Sans to get back and wake him up.

It never happened!

Classic Sans found blue's clothing and fixed it putting it on. He had to remember, be Papyrus with name as Sans. Be hyper, be childish, make sure Paps quit smoking.

Classic Sans's HP and Attack went up like his Papyrus' HP and Attack. Classic Sans don't know the food or if he can still use his magic.

He jumped into the forest and tested his powers that all worked perfectly. He was so glad it was just his stats that's different. He also had a box with things he normally have in it.
