Overview: Nigel West Dickens is selling his tonic to the residents of Fort Mercer when John Marston interrupts him and is disgusted at Dickens selling it to the miserable people for 100 gold coins, forcing Dickens to give to the people for free. Dickens claims the undead won't go near you if you use the tonic. A man walks out to test it, but is savagely ripped apart by the undead. Dickens gives the tonic to Marston telling him to use it as bait. He sends Marston out to collect 5 Desert Sage and 5 Violet Snowdrop and return it to him so he can make a cure.
