Chara makes an indistinct noise that was intended to be 'shut up', and makes a halfhearted attempt at covering their ears. Frisk has gone invisible again, as soon as Papyrus appeared.

Until he actually begins to heal them, because whereever the green touches, flesh collapses to dust in abrupt dessication.
