The other big events all happen simultaneously: Alma and Ellsworth — with the help of a happy Deadwood camp — celebrate their nuptials, Tolliver is stabbed in the gut by Andy, Al's gang of men help Wu oust Lee, and Wolcott hangs himself over the dismay of not being in Hearst's employ any longer.

Did Wolcott hang himself?

Wolcott has hanged himself from the balcony of the livery. At the Gem, Bullock is at the bar, and Swearengen baits him.

Who hung themselves on Deadwood?

Mining scout Francis Wolcott (Garret Dilahunt), a serial killer of prostitutes, hanged himself. He may have been pushed into it by Swearengen's rival, Cyrus Tolliver (Powers Boothe), who disclosed Wolcott's viciousness to his boss, George Hearst.
