Frisk hardly flinched at the sight of Sans' magic. Even as the wisps of powerful blue light surrounded her, heavy and dangerous, she didn't move. On the surface, she trusted Sans. Deep down, she didn't blame him and hoped he would continue. 

He only had to hit her a handful of times. Only half the amount of hits he needed in the genocide runs. It'd be so easy for him.

His voice cut through her thoughts, sending a shudder down her spine. That was it. [i]That[/i] was what scared her. That tone of voice he used, the exact tone she remembered from her many times in the Judgement Hall. She tensed and listened to him, having no other choice but to give him her full attention.

But he didn't say what she expected him to say.

"You took it too far? [i]You[/i] took it too far? S-Sans, that's not true." She remembered those timelines well. It was where many of her nightmares came from. The memory of him slowly torturing her, waiting several long and agonizing moments between each hit. He had wanted her to feel his anger and pain, and he succeeded. 

Frisk winced at the small pain in her wrists, but still didn't struggle. She was quiet, then finally spoke shakily and softly. "I deserved everything you did to me." She sucked in a breath. "And I deserve so much more punishment than that." 

Never once did she think she would ever say those words. She knew it was true, yet had never dared admit it to Sans. 

"I don't want to remember either, Sans. I don't want to be afraid of you. But we can't pretend it never happened...It'll just eat us alive. And you shouldn't have to go through that."
