Since his conception, Hillbilly was told to us as being the unnamed son to Max and Evelyn Thompson. Well, fast forward to the recent reworked Hillbilly, and we look at the new Common add-on 'Dad's Boots'; the description reads: "A pair of trusty boots, pulled from the corpse of Max Thompson Sr." ... you only call someone 'Senior' if they share the same name as their child. Ergo, Hillbilly's name has been revealed to us as Max Thompson Jr.
