There's something new in the save screen. Or rather someone new.
After Frisk unfortunately resets the world, Aftertale Sans, or better known as Geno, is put back into the save screen but once there he is met with a new face.
A crack opens in a breaking universe and Death peeks through to the other side. It seems like this "code" thing hasn't been doing it's job, and there's someone who's long in need of reaping. Death tries to relieve Geno of his suffering though, well, himself, but when that fails, there's no choice but to relieve his suffering some other way, right? Perhaps they could help each other.
