Chara woke up with everyone around. Sans tried to do something like Papyrus from his timeline would do. It worked. No one realized. Sans did say close to what Blue would say. Close enough. Then going out of the barrier Same thing. Sans only had been in 3 true pacifist but, 100 genocide. He acted like his papyrus except the Spaghetti is Tacos and being hyper.

Next thing you know everyone ran down hill almost. Sans was having a little trouble with everything. He would have to go to Underfell later on. Hopefully this doesn't happen there. It is easier with Underswap then Underfell. Now though. He has to keep US Papyrus happy and not knowing about this until the next reset hopefully it works out.
