Short Temperance - S1.E6

There are two things to do at the fort at night – sleep and drink. Lady Hammond seizes on the notion of exercise and temperance after a night of one-too-many. She uses her charms to cajole the men to take the sobriety pledge and Misty Moon's bar falls empty. But the men have to drink something, so MacTavish and Blackfly turn the trading post into a coffee house. Only Lady Hammond doesn't seem to be suffering through this dry spell. Could it be the ingredients in the special blend of "coffee" that she's been drinking?
