I'm glad to offer advice you're taking this well.
Can't wait to see Ch. 3 myself.
As for your talent with dialogue, it really means that you've really "gotten in tune" with your characters and writing their words is natural for you. It takes no effort to do so, so it flows through you and onto the page. I'm sorry if this sounds silly, but I really have no other words to say it at this time.
Good job.
