[Sans winces a little.] I didn't know it was shutting off electronics until I got there. Didn't think the lab guys would just let me in so I let myself in. [So no, he didn't tell anyone, he just teleported in. But he did kind of assume he'd be able to use his phone if he had to.] There were lab reports--didn't take 'em, but they said stuff about how any recording attempts keep glitching out, so I don't think they knew I was there at all.

[Things could have gone a lot worse. Presumably at some point someone who actually works there would have come to check on things if Sans had gotten hurt or something, but--well, who knows how long that would have been.]
