It is clear that no one knows about Anne and Frederick, so there is no reason to predict a reconcilliation.

CW pays Anne very few compliments. The only one I can think of that was publically done was insisting that she ride with Admiral and Mrs. Croft.

Thought I've never been happy with the scene. Anne is so sure it is out of kindness. I've never been happy with that. It seems overly observant. Surely it could have also been a clever way to get Anne out of his sight. But Anne never suspects this. I'm uncomfortable with her powers of observation. They seem almost superhuman.

But back to my point - even if he is kind to Anne, he is not romantic with her. He dances with the girls.

He could have easily prodded one of the girls to play and asked Anne to dance.

There is no reason to suspect that Anne would be an potential match for him. I don't see this as people overlooking Anne. Mary would be first in line to cheer Anne on if it meant HER sister got the Captain over the Musgroves. Elliot pride and all that.
