In this chapter, Jane learns more about Rochester's past, particularly his relationship with Bertha. Much of this information hinges on the problem of excessive sexuality. As Rochester constantly reminds Jane, he is not "cool and dispassionate"; instead, he seems to devour her with his "flaming glance." His passionate nature seems to have contributed to his marriage, and to his current problems. When he first arrived in Spanish Town, Rochester found Bertha dazzling, splendid, and lavish, all qualities that excited his senses. But he soon discovers that she is sexually excessive: "coarse," "perverse," "intemperate," and "unchaste." Rochester implicitly suggests his inability to control Bertha then (as now) hinges on her sexuality: She chose her own sexual partners, refusing to maintain the monogamy required by British moral standards. While he criticizes Bertha's sexual excess, Rochester participates in his own with his three mistresses — Céline, Giacinta, and Clara — and his current attempt to make Jane part of the harem. When he tries to accuse Jane of flinging him back to "lust for a passion — vice for an occupation," she reminds him that these are his choices. She senses that his passion is out of control — he's in a "fury" and glowing like a furnace, with "fire" flashing from his eyes — and Jane needs to walk away from the relationship until he has learned self-control and until she can enter the relationship on a more equal footing.
