Always wondered this on the back of my mind. You have Albert Cole, Natalia Durbravoski and Max Stone - three individuals who are probably as unlikely 'good' Vault Dwellers (meaning they always question authority) would not have volunteered or been selected to find the new Waterchip. Albert with his silver tongue and skill; Natalia with her stealth, lockpicks and thievery; and Max Stone with his superior strength, endurance and heavy hands. Would not a team be more effective? Considering if the Vault dweller did accumulate all the followers would be a much better chance at surviving.
