That's not her being a fraud, or her going in depth about what wines she likes while actually explaining who she herself is. That's just her asking to share a bottle of wine with you after the party, which is exactly what she does. Sorry to say.
Then we understand where we disagree. I believe there is a subtext to that conversation that you are missing and that is part of the reason the chapter 3 seems disjointed.
Btw, the fraud comment was directed at Miles, the MC of the movie Sideways. Highly recommended.
