On previous reads, I've been taken aback by the use of the word 'repulsive' in chapter 6:

Mary was not so repulsive and unsisterly as Elizabeth, nor so inaccessible to all influence of hers

It seemed like JA was making a very unsubtle value judgment about Mary (somewhat vile) and Elizabeth (even viler), instead of letting their behaviour be our guide. But this time I've checked a dictionary and seen that 'repulsive' has an alternative and more specific meaning: distant, cold, and forbidding. I'll assume that that was the meaning JA intended, unless Elizabeth turns out to be substantially worse-behaved than Mary.
