Then, in their first year of Brussels, their old aunt, Miss Branwell, died. That was destiny, the destiny that was so kind to Emily. It sent her and her sister back to Haworth and it kept her there. Poor Anne was fairly launched on her career; she remained in her "situation", and somebody had to look after Mr. Brontë and the house. Things were going badly and sadly at the Parsonage. Branwell was there, drinking; and Charlotte was even afraid that her father ... also sometimes ... perhaps....
She left Emily to deal with them and went back to Brussels as a pupil teacher, alone. She went in an agony of self-reproach, desiring more and more knowledge, a perfect, inalienable, indestructible possession of the German language, and wondering whether it were right to satisfy that indomitable craving. By giving utterance to this self-reproach, so passionate, so immense, so disproportioned to the crime, the innocent Charlotte laid herself open to an unjust suspicion. Innocent and unaware she went, and--it is her own word--she was "punished" for it.
Nothing that she had yet known of homesickness could compare with that last year of solitary and unmitigated exile. It is supposed, even by the charitable, that whatever M. Héger did or did not do for Charlotte, he did everything for her genius. As a matter of fact, it was at Brussels that she suffered the supreme and ultimate abandonment. She no longer felt the wild unknown thing stirring in her with wings. So little could M. Héger do for it that it refused to inhabit the same house with him. She records the result of that imprisonment a few weeks after her release: "There are times now when it appears to me as if all my ideas and feelings, except a few friendships and affections, are changed from what they used to be; something in me, which used to be enthusiasm, is tamed down and broken."
At Brussels surely enlightenment must have come to her. She must have seen, as Emily saw, that in going that way, she had mistaken and done violence to her destiny.
She went back to Haworth where it waited for her, where it had turned even the tragedy of her family to account. Everything conspired to keep her there. The school was given up. She tells why. "It is on Papa's account; he is now, as you know, getting old, and it grieves me to tell you that he is losing his sight. I have felt for some months that I ought not to be away from him; and I feel now that it would be too selfish to leave (at least as long as Branwell and Anne are absent) to pursue selfish interests of my own. With the help of God I will try to deny myself in this matter, and to wait."
