Quote 19
"Jekyll," said Utterson, "you know me: I am a man to be trusted. Make a clean breast of this in confidence; and I make no doubt I can get you out of it."
"My good Utterson," said the doctor, "this is very good of you, this is downright good of you, and I cannot find words to thank you in. I believe you fully; I would trust you before any man alive, ay, before myself, if I could make the choice; but indeed it isn't what you fancy; it is not as bad as that; and just to put your good heart at rest, I will tell you one thing: the moment I choose, I can be rid of Mr. Hyde. I give you my hand upon that; and I thank you again and again; and I will just add one little word, Utterson, that I'm sure you'll take in good part: this is a private matter, and I beg of you to let it sleep." (3.10)
Mr. Utterson offers his unconditional help to Dr. Jekyll; Dr. Jekyll says he trusts Mr. Utterson unequivocally, but refuses the offer.
Quote 20
"Dear Lanyon,—You are one of my oldest friends; and although we may have differed at times on scientific questions, I cannot remember, at least on my side, any break in our affection. There was never a day when, if you had said to me, 'Jekyll, my life, my honour, my reason, depend upon you,' I would not have sacrificed my left hand to help you. Lanyon my life, my honour, my reason, are all at your mercy; if you fail me to-night, I am lost. You might suppose, after this preface, that I am going to ask you for something dishonourable to grant. Judge for yourself." (9.3)
Dr. Lanyon and Dr. Jekyll actually have a strong friendship—or at least Dr. Jekyll thinks so.
Quote 21
To cast in my lot with Jekyll, was to die to those appetites which I had long secretly indulged and had of late begun to pamper. To cast it in with Hyde, was to die to a thousand interests and aspirations, and to become, at a blow and forever, despised and friendless. (10.16)
Even Dr. Jekyll admits that Mr. Hyde has no friends.
