I bet whoever their Marshall adviser was having fits with the finale. No way would her house not be watched from the time her sister became a suspect. Rafe would not have made it out of the house with those drugs. Also, the suitcase would still positively reek of drugs to a narcotics dog or a test. And Stan would be unemployed after locking a FBI agent in the closet.
But if I turn off my brain, I enjoyed the episode. And I glad the drugs were not in her secret hiding spot that was hinted in the letters.
And it was pretty funny that it was being used to chalk a baseball field. Gives new meaning to High Fly Ball!
