You and Frisk stayed with them overnight.

Frisk: Would you like me to give you a really long tour of the city tomorrow? ~

Chara: I'm going to stab you....

Asriel: Frisk, don't you dare...

Frisk: This is just revenge for all of you! You also did when I fell into the underground.

Frisk grinned, but received a portion of blows from Chara. You laughed about it, while Frisk was left to threaten Chara.

Frisk: Hey! I'll set Sans on you!
