So you were tasked with guarding the house while Toriel and Asgore faced Bete Noire in the stadium thingy and Chara went and tried to save Asriel. You failed. Some of the pink things that Bete Noire made showed up at the house and attacked you. You destroyed them, but the house was also completely wrecked. Like 2 out of 3 of the house were gone. You leaned against one of the mostly destroyed walls and rested for a bit when- "sup." You looked towards where the voice came from. It was Sans.
