Answer:
The lines describing Dr. Jekyll that confirm the prediction are:
* “On the 12th, and again on the 14th, the door was shut against the lawyer.”
* “The doctor, it appeared, now more than ever confined himself to the cabinet . . .”
* “. . . he was out of spirits, he had grown very silent, he did not read . . .”
Explanation:
As the story advances and Dr. Jekyll become more and more controlled by the interaction with Mr. Hyde and all the ups and downs in his personality and behavior every time the exchange happens, Mr. Utterson learns to identify how the Dr will act, and these lines show that he is starting to have the unstable behavior that is related to Mr. Hyde.
