Sans woke up on his mattress. What was it? A reset.

Kid played around with resets and saves, and Sans could remember everything that happened in other timelines. How ironic that this time, Frisk was not there.

"...Human...don'cha know how to greet a new friend?..."

He repeated this phrase again when he noticed that you...Not Frisk. A completely different person, with a different soul...What the hell?
