NightChaosCat asked: "Wait I just noticed the knife, what is Frisk doing with it?"

Ha! That's what Chara gets! Frisk couldn't physically hurt Chara, even if she tried to... So she uses Chara's prized Possession as a threat. Which means she either eats, sabotages, or even puts stuff on Chara's chocolate. So yeah, also it made me so happy that somebody noticed the knife. I don't know... Frisk is gonna be more savage as you get to know her!
