You were in Snowdin with Vanilla and Cream the Rabbit but something went horribly wrong. Chara found Cream and slashed at her. Vanilla ran to go save her daughter but it was too late as the knife stabbed her head...Her own daughter died and she failed...as she could bearly hold her spear. You pulled her into Waterfall and covered the entrance with a large rock.

Vanilla the Rabbit: "I-I...failed to save my own daughter. I'm a horrible mother. I can't save anyone. Why should I bother to keep going. We're all that's left."
