I see... Well, I'll be sure not to replay that static anywhere near you. [Because, you know, he recorded some of it and could do that. Was planning to dissect the audio and listen to it, maybe aloud through speakers to emulate the experience again, but no. Just in his own head, if at all. It's something of an olive branch, or an apology, or just a promise. One that, with that one tangle of unexpected sharp fear shoved aside, lets him add:] If I do sound at all staticky... It won't be on purpose! And would be better dealt with, with a little bit of physical distance. Like me taking a walk. Or you popping off to one of your hideaway spots for a few.

[He's not asking for a promise from his brother here. Partly, because it's almost never worth doing, Sans hates making promises. Partly because no promise can really be guaranteed, when voidgod thoughts might trickle in and forget that Papyrus's chassis is actually an important part of him and not something to swat aside to free his soul or something. But... he'd really like Sans to promise to try to, anyway.]
