When The Junior Deputy finds Aaron "Tweak" Kirby, he can be found inspecting the underside of the dumpster at Aubrey's Diner. When the Deputy talks to him, he explains that he is a self-styled chemist that is against the Project at Eden's Gate Cult working on "performance enhancers" for The Resistance and offers to make these "performance enhancer" drugs for the Deputy who he surmised is also an enemy of the Cult. However, he is low on supplies.

When the Deputy returns to Tweak, he tells them that he is planning on diversifying his product line and is working on a drug called Furious to enhance a person's strength. Tweak wants the Deputy to test out the Furious drug by punching his captive Angels into the town's fire pit. Then to kill all the remaining Angels left. After completing the test, Tweak is delighted that his drug worked and gives the Deputy the recipe for Furious. Tweak urges the Deputy to use his recipes for good, which Tweak hopes will make up for his father's transgressions.
