At her words, Sans looked at her, a mix of pain and rage taking over his features. He couldn't control the drop in his tenor, something darker and eerie as he all but shouted,"A N D  N E I T H E R  D O  Y O U!"

It took him a moment to realize that he'd begun squeezing Frisk's wrists again.

Instantly he dropped them and backed away, not missing the angry red rings where his grip had been. They would probably bruise. Why couldn't he control himself? Was he really so monstrous?

"I'm sorry..... I'm so sorry... You were just a kid........ You didn't know what... You couldn't know that it would turn out like this......."
