In the season 6 finale and the recap at the start of this episode it shows Henry Spencer getting shot, he spins around left shoulder first typically indicating he was shot on that side, however later when Shawn flips him over they show the bullet wound is on the right side of his chest.
When Shawn breaks into the Feed Everyone warehouse, the deadbolt is already unlocked.
As Shawn and Gus enter Jerry's house, Shawn notices the car keys and wallet on the table while in "slow-motion". Just before they enter that room, Shawn starts walking incredibly slowly (to give the illusion of slow-mo camera work)...but Gus continues on at his regular pace. After Shawn takes in the room, the filming speeds up again.
When Shawn and Gus sit on the sofa under which there is a mine, Shawn shows terror in his face before he actually sits down and activates the mine. Then, the officer tells Shawn and Gus that an officer will be coming in to freeze the mine, but the scene immediately cuts to the robot coming in to extract the mine.
Lassiter is wearing a wedding ring when he drops Shawn off to go get Carp.
