Answer:
The two excerpts from Franz Kafka’s The Metamorphosis that show how Gregor’s sister, Grete, transformed in the story are:
* "It's got to go," shouted his sister, "that's the only way, Father. You've got to get rid of the idea that that's Gregor. We've only harmed ourselves by believing it for so long
* All the time, Grete was becoming livelier. With all the worry they had been having of late her cheeks had become pale, but, while they were talking, Mr. and Mrs. Samsa were struck, almost simultaneously, with the thought of how their daughter was blossoming into a well built and beautiful young lady
Explanation:
Grete was the only person who accepted Gregor as he was after his transformation, he was automatically rejected by everyone in the family when he became a big bug, then as years passed by Grete started to reject him too, and even demanded her parents to get rid of him since that thing could not be her brother.
