In your au, how did sans become g!sans? Do you have a list of pages of your echotale comic?
I am VERY happy you emphasized the “in your au”part :’DDD because…yes, this just fanfiction au - not canon ;) I am working on the next update at this moment, it will be dealing with Frisk and Sans’s first meeting, the experiment and how G! was “happened to be”. I think it also might be a bit hilarious there :’DD hope you’ll have fun! The first 14 pages might be up today - next 10 pages will be dealing with the first experiment! And the next ones with a bit about Frisks various friendships with Papyrus, Sans, Alphys and the disaster that caused the SHIFT. This will also explain why G! exists and why he and Frisk are the only ones left (although tis I already explained in other posts I think). The list of pages isn’t up but since there are so so many people asking for it, I might try doing it soon >__<;
