How does Miss Kinnian react when Charlie returns to night school?
In the story, Flowers for Algernon, Charlie is the main character and Miss Kinnian is his teacher. At first, Charlie does not understand much of school but tries hard. Miss Kinnian recommends him for a scientific experiment to raise his intelligence. That is successful for a while, but then fails and Charlie returns to what he was.
When Charlie shows up at school, Miss Kinnian is taken aback as Charlie sits in his old seat and picks up his old books. She knows how intelligent Charlie was as a result of the experiment, and it hurts to look at him trying so hard again with so little intelligence or aptitude for school. Seeing her aghast reaction, Charlie remembers that he no longer goes to this school. She tries to soften the blow for him because he was her favorite student, but he leaves anyway. She is left to wonder what happens to him as he does not return. I think she wonders whether she should have disturbed Charlie in his innocent first life before the experiment when he was happy on his terms.
