Deadwood breathes easier when some riders arrive in town with the smallpox vaccine, and word of a possible treaty with the Sioux. The results of Bullock's analysis of her gold claim move Alma to reassess her plans and sets up a confrontation between Bullock and Swearengen. When Flora tries to quit, Cy teaches Joanie a deadly lesson at the expense of a couple of con artists.—WyattJones
Some of the riders sent out to get the smallpox vaccine return with the precious medication but also with other news: a treaty has been signed with Indians. The news leads Al Swearengen to decide on a new tack as far as Alma Garret's claim is concerned. Whitney Ellsworth assays Alma Garret's claim and determines that it's a bonanza and she decides to stay in Deadwood. Trixie tries an alternative to returning to work at the Gem. Flora seems upset at the killing in the Gem and turns to Joanie for comfort. It turns out Flora and Miles aren't exactly the innocents they've made themselves out to be. Cy Tolliver knows exactly what to do.—garykmcd
