At the beginning of the episode, when Deacon Joe is shaving, the date is given as June 10th 1993, but this is happening in the later timeline of 2016.
Deacon Joe is seen putting blue contact lenses in as part of his disguise, but when his photo is shown on the television you can see that he already has blue eyes.
When Frank is packing and he and Satch are arguing, Frank calls Satch the wrong name. The line is: "It's a lack of loyalty, Stan, to me."
