In an earlier thread, there was some discussion of how the Crofts seem to be a good team. I've been keeping this in mind as I continue reading, and am finding the "teamwork" theme echoed in other relationships.

Look at the Harvilles, for instance, when Louisa is injured: and a look between him and his wife decided what was to be done. She must be taken to their house; all must go to their house, and wait the surgeon's arrival there. They would not listen to scruples: he was obeyed: they were all beneath his roof; and while Louisa, under Mrs. Harville's direction, was conveyed upstairs, and given possession of her own bed, assistance, cordials, restoratives were supplied by her husband to all who needed them. There was a need, they both recognized it and knew the right thing to do, and just made it happen. We've already seen how another couple manages a crisis in this book; when little Charles fell and broke his collar bone, this certainly wasn't what we saw from Mary and Charles. But in the Harvilles we have another example of two minds working as one.

Now look at what's going on with Anne and Wentworth. When Louisa falls, Wentworth is too stunned and upset at first to think for himself (surprising for a Navy commander, IMHO, but that's a topic for another thread) and so Anne takes full control, which he implicitly knows and acknowledges to be the thing to do. But later, once he's more himself, we see this interaction as they're approaching Uppercross: I have been considering what we had best do. She must not appear at first. She could not stand it. I have been thinking whether you had not better remain in the carriage with her, while I go in and break it to Mr. and Mrs. Musgrove. Do you think this a good plan? She did. While it's not an unspoken interaction, they just know what needs to be done and that they'll work together for the good of the Musgroves and Henrietta.
