There is a quickness of perception in some, a nicety in the discernment of character, a natural penetration, in short, which no experience in others can equal, and Lady Russell had been less gifted in this part of understanding than her young friend. But she was a very good woman, and if her second object was to be sensible and well-judging, her first was to see Anne happy. She loved Anne better than she loved her own abilities; and when the awkwardness of the beginning was over, found little hardship in attaching herself as a mother to the man who was securing the happiness of her other child.
For those who have a hard time appreciating Lady Russell as a person and want to think her more a villianess than I think she deserves I dearly love the phrase "She loved Anne better than she loved her own abilities" This is where you learn that LR truely had Annes best interests at heart the whole time-not her own convenience in having Anne near her or any other theory as to why she would interfer so in Anne's life. She wanted her safe and happy.
