But Grete's words had made her mother quite worried, she stepped to one side,
saw the enormous brown patch against the flowers of the wallpaper, and before she
even realised it was Gregor that she saw screamed: "Oh God, oh God!" Arms
outstretched, she fell onto the couch as if she had given up everything and stayed
there immobile. "Gregor!" shouted his sister, glowering at him and shaking her fist.
That was the first word she had spoken to him directly since his transformation.
She ran into the other room to fetch some kind of smelling salts to bring her
mother out of her faint; Gregor wanted to help too - he could save his picture
later, although he stuck fast to the glass and had to pull himself off by force; then
he, too, ran into the next room as if he could advise his sister like in the old days;
but he had to just stand behind her doing nothing; she was looking into various
bottles, he startled her when she turned round; a bottle fell to the ground and
broke; a splinter cut Gregor's face, some kind of caustic medicine splashed all over
him; now, without delaying any longer, Grete took hold of all the bottles she could
and ran with them in to her mother; she slammed the door shut with her foot. So
now Gregor was shut out from his mother, who, because of him, might be near to
death; he could not open the door if he did not want to chase his sister away, and
she had to stay with his mother; there was nothing for him to do but wait; and,
oppressed with anxiety and self-reproach, he began to crawl about, he crawled over
everything, walls, furniture, ceiling, and finally in his confusion as the whole room
began to spin around him he fell down into the middle of the dinner table.
