Deadwood

With the boy that Bullock is charged with raising (his nephew) now conveniently out of the picture, will Bullock keep his obligation to stay married to his brother's wife?
I would think his obligation to the widow Garrett is also important and that his borther's widow (Bullock's current wife) would allow for a quiet divorce in order to free Bullock to do the right thing and raise his child with the widow Garrett. Then again, Ellsworth could step in and the problem is solved.
I can't get enough of that show, although occasionally Al Swearingen speaks in ways that are too heady, even for Deadwood standards. His rebuke of A W at the beginning of this week's episode for putting too many rumors in his paper is an example, but all in all, the show is superb.
