that Henry really didn't do much beyond make a ton or recommendations (no action taken on them that we are aware), and flirting with Julia and Maria. But Edmund is not aware of Henry's games with sisters, so why should Mary address the sentiment of Henry's "accomplishments" to Edmund at all? It would go completely over his head. Mary then must have been talking to herself. We don't get Edmunds reaction to her statement. Although Edmund promptly dismisses Henry's suggestions (before Mary speaks), it's rather because he's clear on his idea of a living and plans not to be persuaded away from what he knows he will do. So, I still don't think it's completely clear. And Henry rather continues in the vein of "improvements" and starts another animated telling of that to Fanny, so if Mary is angry and was making her references to be understood by anyone who would understand, such as Henry, it rather went over Henry's head, too.
