Quote 10
"I see genuine contentment in your gait and mien, your eye and face, when you are helping me and pleasing me—working for me, and with me, in, as you characteristically say, 'all that is right:' for if I bid you do what you thought wrong, there would be no light-footed running, no neat-handed alacrity, no lively glance and animated complexion. My friend would then turn to me, quiet and pale, and would say, 'No, sir; that is impossible: I cannot do it, because it is wrong;' and would become immutable as a fixed star. Well, you too have power over me, and may injure me: yet I dare not show you where I am vulnerable, lest, faithful and friendly as you are, you should transfix me at once." (2.5.140)
Later in the novel, Rochester’s going to do his best to convince Jane to do something that she thinks is wrong, but notice that at this much earlier stage he already knows she’s not the kind of person who can be convinced of something she disagrees with. Also, this passage suggests that, even though Jane kind of gets a kick out of being Rochester’s servant, she won’t obey just any order.
Quote 11
"[S]uppose you were no longer a girl well reared and disciplined, but a wild boy indulged from childhood upwards; imagine yourself in a remote foreign land; conceive that you there commit a capital error, no matter of what nature or from what motives, but one whose consequences must follow you through life and taint all your existence. Mind, I don’t say a crime; I am not speaking of shedding of blood or any other guilty act, which might make the perpetrator amenable to the law: my word is error. The results of what you have done become in time to you utterly insupportable; you take measures to obtain relief: unusual measures, but neither unlawful nor culpable. Still you are miserable; for hope has quitted you on the very confines of life: your sun at noon darkens in an eclipse, which you feel will not leave it till the time of setting. Bitter and base associations have become the sole food of your memory: you wander here and there, seeking rest in exile: happiness in pleasure—I mean in heartless, sensual pleasure—such as dulls intellect and blights feeling. Heart-weary and soul-withered, you come home after years of voluntary banishment: you make a new acquaintance—how or where no matter: you find in this stranger much of the good and bright qualities which you have sought for twenty years, and never before encountered; and they are all fresh, healthy, without soil and without taint. Such society revives, regenerates: you feel better days come back—higher wishes, purer feelings; you desire to recommence your life, and to spend what remains to you of days in a way more worthy of an immortal being. To attain this end, are you justified in overleaping an obstacle of custom—a mere conventional impediment which neither your conscience sanctifies nor your judgment approves?" (2.5.148)
No matter how long and sad the story is, we can tell that Rochester’s trying to trick us into saying "yes," and so can Jane. When we find out that what he’s calling a "mere conventional impediment" is the law against bigamy, well, the trick’s just a lot more obvious then. Still, his story does inspire a lot of sympathy.
Quote 12
"Now for the hitch in Jane’s character," he said at last, speaking more calmly than from his look I had expected him to speak. "The reel of silk has run smoothly enough so far; but I always knew there would come a knot and a puzzle: here it is. Now for vexation, and exasperation, and endless trouble! By God! I long to exert a fraction of Samson’s strength, and break the entanglement like tow!" (3.1.38)
Rochester sure gets compared to Samson a lot—you’ll really have to check out that reference in the "Allusions" section. And, as usual, Rochester is shuffling around names and labels for things in order to try to change our attitudes toward them—that "hitch in Jane’s character" is actually her morality.
