I think what really works best for me in this episode is the addition of Turnbull to the roster. Turnbull serves as the perfect character to really absorb the sillier aspects of Fraser's mountie-ness.
There's a certain amount of foolishness about being Dudley Dooright that the writers wanted to get across, yet they also want to see Fraser as proper knight in dress-reds. With Turnbull in there, Fraser himself can laugh at how goofy a mountie can seem.
As far as the rest of the episode goes - it also starts to get rolling on the good character development in peripheral characters, really filling up the episode with great opportunities for banter and emotional investment in heroes and villains.moreless
