If you don't watch this episode closely, it could get mighty confusing. A warehouse is blown up for no apparent reason, Nash rides through the Bay in a cigarette boat for no apparent reason, and Joe is terrorized by a thug for a key Joe knows nothing about. First, Joe is pepper sprayed, then forced to ride an exercise cycle to exhaustion, and finally blown aback by an explosion.
All this confusion hides a simple story of a mobster who has had his face surgically altered. The underlying motives for this episode seems to be to justify expensive boats and cars. Raymond Peck/Louis Fallon (George Hamilton) just happens to be a boat enthusiast, hence Don's cigarette boat (no doubt one of Don's toys from his MIAMI VICE days) is incorporated into the script. The departing Caitlin sells her Zebra sports car to Harvey, so that the car is not wasted when Caitlin exits the show. And to further jazz up such extraneous elements like boats and cars, a spectacular explosion always helps.
The season finale has the entire cast and crew transported to Las Vegas. This seems entirely par for course for lavish and expensive production costs. Hey, if they can throw in their boats and cars, a trip to Vegas is a natural. It might seem un-natural to the storyline, but who cares - everybody's having too much fun.
