Asriel is quiet for a little longer. What he wants to do is nuzzle back, bury his face in her fur and cry until he's all cried out. But at the words "we're here for you", he knows what he has to do.

He pulls away from her grip a little, tiny hands still holding onto her shoulders.

"Mom... I... I did something really terrible."

He doesn't want to tell her. He doesn't want to see the look on her face when he does. He doesn't want to see the look of disgust, or the horror when Toriel realizes the kind of demon her son's turned into.

"Something you might hate me for."
