Their lips press thin and their shoulders shake, just briefly. To make Chara suffer as they had...leaving them alone in this place after wishing they would return so badly. Is that really what they wanted? What they would have done?

Don't kill, and don't be killed. Funny how hard that promise is to uphold.

"You would be missed," they murmur, but the conviction isn't there. Asriel would miss them, yes, and Toriel, if she knew. Peter as well, but...it's distant relations, ones Chara would never acknowledge. No, they would see all the pain in the hearts of those Frisk has fooled, and blame themself for it. Take the sin upon themself, as if they had wished for it in the first place.

Every way they turn, it's only more pain. When did it become this way?

Frisk sniffles, swallows hard, and looks up again, forcing themself to meet Chara's eyes. "I...I'll go back. 'M sorry."
