April's nail color changes inexplicably throughout the episode. During the scene at Boris' party and afterwards that evening, April is shown with black nail varnish. The next morning when she arrives at Evan and Hank's motel room, her nails are unpainted or clear. She is later shown inside the motel room waving, touching up her make-up, and doing other things with her hands, revealing that her nails are still unpainted or clear. However, when Devya knocks on the door, April answers it, laying her right hand along the door jamb and revealing that her nails are now painted black again.
During Tucker's collapse, his left pant leg gets rolled up to his knee without anyone touching it (possibly due to an action removed in editing).
Stephen Poplawski invented the blender.
Hank is called to Tucker Bryant's house because of a car accident. Two small blood stains on Tucker's shirt can be seen, which he tells Hank is his girlfriend's blood. In the next scene you see an additional and much larger stain appear, but Tucker has no open wounds which would cause this. (In close-up, only the bloodstains over Tucker's heart can be seen, but in wider shots a much larger second patch can be seen at and below his lowest rib. This is all supposed to be his girlfriend Libby's blood; Tucker never points to just the stains over his heart.)
By the difference in sound quality, Libby's "Who are you, MacGyver?" was obviously added in post rather than recorded on set.
Hank and the helicopter EMS crew move Tucker up from the rear of the helicopter to load him in. EMS personnel do not ever approach a helicopter from the rear. This puts them out of the sight of the pilot, and more importantly, brings them right by the tail rotor, which can be extremely dangerous.
When the woman hank saved becomes enamored with him he says that she has Nightingale Syndrome but Florence Nightingale Syndrome is when the savior develops a strong emotional connection with the person they rescued (fairly common among doctors and caregivers). What Hank should've said was that she had White Knight Syndrome, a condition where someone develops a connection with someone who saves them.
