The Governor's Pleasure (S03E01)

After Bea receives a life sentence without the possibility of parole for Brayden Holt's murder, Ferguson asserts her dominance, declaring that Bea is now under her control. When Bea leverages her position as Top Dog to retaliate, Ferguson retaliates by putting Bea in solitary and releasing Liz from Protection, which leads to Liz being viciously attacked by Boomer. However, Ferguson misjudges Bea's resolve, as Bea incites a riot among the inmates. With the prison in lockdown, Ferguson is forced to seek Bea's help to restore order. The power struggle becomes clear: Wentworth belongs to Bea, not Ferguson.
