Seizure. Sans...thinks he's heard the word before, but he has no idea what it means. But if it's the reason he called Max, then it must have been bad. Probably a human thing--that would explain why he reached out to another human.

And she did rewind. It's nice to have confirmation. And--Tim knows already? That's a bit of a relief, at least. It's nice he didn't force Max's hand this time.

Max is looking at him when she asks if they're all okay.

"i'm--"

Tim cuts him off before Sans can think of a way around the truth. Right. Chasing Tim through the woods, reminding him of his worst nightmare, and he should have known better. But teleporting is just...easier than running. If he'd followed on foot, he would have lost Tim by now. And then--

Right.

"i'm sorry. i didn't...i wasn't thinking. i just didn't want--you to--"

Dammit, no, he's done enough damage already, he can't just say that in front of Max. He has to...there has to be some way around it.

"i--dammit."

Trying to resist makes his skull hurt even more, and he curls his fingers against the bark, other hand covering both eyesockets. He can't help a quiet hiss of pain.

"i didn't want--to--lose you. so--i was teleporting."

There. That's good enough. Hell, it's as close to a pun as he can come during this event.
