Let me correct.

Chara says, " ... what? You didn't do/say that? ".

This is only explainable if Frisk corrected them. They are posing the question to Frisk. If they just noticed that Frisk didn't say it, the dialogue would be more like "...wait, no you didn't." Chara asks Frisk a question that is clearly not rhetorical. Chara is speaking both ways with Frisk.

Unless you can show why they would ask a rhetorical question in that way and under those circumstances.
