Don't kill, and don't be killed. Sans turns the words over and over again in his skull. What a...straightforward sort of way of thinking. Almost to the point of novelty. It's not a mindset he's ever really had the chance to get into. But he supposes that...to some people, it's the best ideal to aspire to. And that's not necessarily a bad thing.

Something to think about later, at least. Something better than this.

"i promise," he says again. "no picking fights. no dying either."

Not everything has been good for him here, but not everything was good for him back home, either. He's alive, here. He has a family again here. That's worth a lot. Even if, in Sans' mind, it's also worth doing anything to defend. But Frisk's opinion of him means a lot, these days. So he'll genuinely try to keep those promises, this time.

Between the two of them, they should soon be able to get a deep enough hole dug. It's not like it needs to last for long, after all.
