Disher says the address for Zach Ellinghouse is 418 Vinton apartment 3D, but they arrive at a building numbered 601.
Trudy is buried in a different cemetery from the one she was buried in previously in Mr. Monk and the Red-Headed Stranger (2002).
While Kevin and Monk are making potato salad, the rectangular container where Monk will spoon the finished potato salad disappears and reappears in the series of shots, including disappearing after Monk has spooned the salad into the container and Natalie took a bite from it.
Natalie sits at a coffee shop counter holding a picture of Trudy. When "Trudy" enters, the position that Natalie uses when she is attempting to hide it switches between upside down on the counter and held to her chest.
When Stottlemeyer is leaving the cookout to go to the crime scene, he tries to distract Monk by telling him to clean the grill. There are several hamburger patties and several pieces of chicken on the grill, but when the camera pulls back, the pieces of chicken have vanished.
[18:53] When the group is talking about the recent death of Zach Ellinghouse during the backyard cookout, lighting equipment is visible on the right side but is not visible in the wide shot.
