The two excerpts that best reflect Gregor's isolated condition after his transformation are:
1. He got into the habit of closely watching it for one or two hours before it was opened and then, lying in the darkness of his room where he could not be seen from the living room, he could watch the family in the light of the dinner table and listen to their conversation—with everyone's permission, in a way, and thus quite differently from before.
2. Gregor never responded to being spoken to in that way, but just remained where he was without moving as if the door had never even been opened. If only they had told this charwoman to clean up his room every day instead of letting her disturb him for no reason whenever she felt like it!
The excerpts are taken from 'The Metamorphosis' by Franz Kafka. The above two excerpts reflect how Gregor's isolated condition was after he transformed.
For instance, he used to spend time in his dark room, watching things for hours without him being watched by anyone else. Also, he never liked communicating with any of his family members.
