Toriel might--but she's somewhere far, far away right now, and Frisk is the only one around.

Chara keeps their head down, rocking until the raggedness of their breath is quieter, and the trembling has slowed. They hate how everything is different when Frisk is around, and they especially hate how if they weren't so furious, this horrible feeling in their chest would feel like tears. They're upset. They've gotten all worked up over some bullshit innocent reassurance that Frisk probably couldn't help but give, and now they've gone and hurt them just by being themself, and they still can't unclench their jaws.

They think over Frisk's words and press their face harder into their arms. There's nothing offensive about them at all. They're sweet. Misguided.

They're not going to uncurl from the ball while Frisk is still here. They plan to wait, and maybe not even move for a long while after they've left.
