"It's interesting how this thing sounds," the girls seemed to be getting ready to leave the store, but Varya, as a last gesture, lightly tapped her finger on the gramophone needle. The sound it produced was... Unexpected. Heart-wrenching. As if someone had screamed, but people don't usually scream like that... People scream when they call out to someone, or when they want to get attention, or when they are in a state of joyful excitement, or when they show off their courage by doing something risky (jumping from a tree branch into a snowdrift?). People don't scream like that... As if death had struck them in the chest with a bony fist. At least, Varya had never heard such a scream before. Pale with some vague premonition, the girl, as if hypnotized, went outside, where three students in their school uniforms could be seen in the distance. No, it seems like four? Wait...

After that, instead of classes, they were all sent to their rooms and told to appear individually for a personal conversation with Duncan or Carvia.

She is going to Miss Carvia.
