If you don't mind my taking this thread off on a slight tangent, I'd like to expand on this idea of the hints we're getting about who Wentworth really is.

As you mentioned, in this week's chapters he's not behaving at his best, but there are a few times when we start to see glimmers of his better side. Certainly in this scene with Mrs. Musgrove, and when he insists that Anne take the carriage back from the long walk. I often wonder if this shift to his warming up to her was predicated by the conversation he had in the hedgerow with Louisa, or if he would have come to her assistance regardless. Either way, we're starting to see that he's not all resentment and anger.

There's an early incident, though, that I'm not sure how to interpret, and might be seen as reflecting FW in a number of different ways. From Chapter 7:

The morning hours of the Cottage were always later than those of the other house, and on the morrow the difference was so great that Mary and Anne were not more than beginning breakfast when Charles came in to say that they were just setting off, that he was come for his dogs, that his sisters were following with Captain Wentworth; his sisters meaning to visit Mary and the child, and Captain Wentworth proposing also to wait on her for a few minutes if not inconvenient; and though Charles had answered for the child's being in no such state as could make it inconvenient, Captain Wentworth would not be satisfied without his running on to give notice.
