Everything is going smoothly at the fort; well, maybe not so smoothly. Entwhistle is gunning for action, Blackfly wants a raise, Misty Moon's supply of liquor seems to have come up short again and Colonel Boyle is battling foes of his own; kidney stones. When Blackfly asks MacTavish for a raise the thrifty Scot sites supply and demand as the reason not to reward Blackfly for all his hard work. Blackfly takes matters into his own hands and MacTavish gets a taste of supply and demand he wasn't expecting.
