[If Chara is attempting to get on her bad side, it seems to be working. The next words are written slowly, as Toriel has to move very deliberately to avoid crushing the marker in her hands or against the mirror.]

I am Empress Toriel, Ruler and Protector of Monsters, and Scourge of Humanity.

Whether my memories are real or not, I know who I am, and what I am capable of.

I look forward to the day that I will be able to show you how competent and effectual I truly am.
