Ep 16, "Requiem for a Gleet":


Cochran contemplates a procedure that could cure Swearengen, or kill him; His employer indisposed, Dority must attend to a former fellow-bushwacker come to request Swearengen’s permission to pull a job, and to Wu, who attempts to convey news of a “tong” rival newly arrived from San Francisco; Bullock attempts to settle into domesticity, while Star gets a new combination bookkeeper/roommate – Trixie; Alma cuts ties with Sofia's tutor, Miss Isringhausen, who takes refuge with Adams; and the arrival of county commissioner Hugo Jarry (Stephen Tobolowsky) spawns rumors about the camp's future and legal ownership of the gold claims. Written by Ted Mann; directed by Alan Taylor. (source: BTN)

The day after the bladder-stone scene, there is an encounter between Dan Dority and E. B. Farnum. Standing at the bar of the Gem, E. B. reports that his sleep the previous night was disrupted by pain-filled screams. Dority, determined to conceal that Al is seriously ill, refuses the bait:
FARNUM: I heard screaming. From Al's room.
DORITY: Happens up there many a f***ing evening.
FARNUM: Al was f***ing screaming, Dan. And I'm wondering how he's feeling this morning. And you dancing around the pole ain't allaying my f***ing anxieties.

There is a scene between Mr. Wu and Dan Dority. Wu comes to the Gem in agitation, having just spied a member of a rival San Francisco tong, freshly arrived on a stagecoach and already in conversation with one of Swearengen's business competitors. Because Al is still indisposed by illness, Dority tries to handle the conversation. But Wu's side of the dialogue is limited to gesticulations and the exclamations, "Swearengen!," "c***sucker!," and "San Francisco!" He says "c***sucker" about ten times, with increasing vehemence, until Dority, whose English isn't all that grammatical, either, gets the drift.
