Between the initial chase scene and the flashback later in the episode, Henry and the female runner's positions change. Also, in the initial scene, Henry takes off his sunglasses before Shawn and Gus pass, but in the flashback he is wearing them again.
When 'Curtis Stanzen' takes off on the dirt bike, in different shots there are one or two skid marks in the street between the Blueberry and Lassie's sedan.
When Vick first appears with the box of her belongings, her left hand jumps on and off it between shots.
The autopsy report for Stanzen incorrectly lists the yellow discoloration of his skin and eyes as cyanosis; cyanosis is when skin turns blue due to a lack of oxygen. Yellowing of the skin and eyes is called jaundice, which is caused by a buildup of the byproducts of dead red blood cells called bilirubin. Bilirubin is normally filtered out of the blood by the liver, which is why jaundice is one of the main signs of serious liver dysfunction.
When Shawn and Gus are reading Curtis Stanzen's arrest record, "Guilty" is misspelled as "Gulity".
