Answer:
They both become agitated at the mention of the other’s name.
Explanation:
This is the sentence that best describes a similarity between Dr. Jekyll and Mr. Hyde. We learn that when Mr. Utterson mentions Dr. Jekyll to Mr. Hyde, he becomes angry and refuses to believe him. Moreover, when he mentions Mr. Hyde to Dr. Jekyll, he turns pale and refuses to listen any more. Therefore, we see that both characters become agitated at the mention of the other's name.
