How do two central ideas develop in chapter VII?

In Chapter Seven, we see that Edna is a bit different from the other women. Yes, she's beautiful, well-mannered and graceful, but that isn't what you see right away. What we notice in this chapter is her llack of reserve. She's opening up.... taking another woman in confidence..... giving voice to things likely better kept unsaid.

Edna also admits to impulsiveness as a child and looks back on that trait fondly. She admits to feeling the same way during this summer.

But do you know," she broke off, turning her quick eyes upon Madame Ratignolle and leaning forward a little so as to bring her face quite close to that of her companion, "sometimes I feel this summer as if I were walking through the green meadow again; idly, aimlessly, unthinking and unguided."
