During the end scene at the beach, Kelly's (Jaclyn Smith) face is clearly visible in the sun, with her hair back, and there is no trace of the bullet wound to her forehead.
As with series finale (Let Our Angel Live (1981)), there is no "blood make-up" visible on Kelly as she brings her right hand up to her forehead.
When Kelly wakes up from brain surgery at the hospital, she is wearing perfect '80s makeup. A discreet "nude" palette would have been better suited to fake being "bare faced" yet still "camera-ready". Also, she is wearing the same rouge and eye-shadow as Farrah (Jill), who is herself sharing the same coffee lip-gloss as Sabrina.
As Skip hold the gun towards Kelly, the cylinder in the revolver has an empty chamber. This is the active chamber in the revolver. The cylinder can be seen to turn to the empty chamber as he pulls trigger.
Later in the show, as Jill (with Sabrina as a passenger) "screeches to a halt" at the park, the brake lights on her car do not come on.
BTW, license plate: California 861 BMG. It is unclear why her car (the white Mustang Cobra II) has different plates here and there during the series run.
After being shot in the head, Kelly, with her left hand, continues to hold on to the cotton candy throughout her fall to the ground.
Kelly gets shot in the head for the first time. She is shot by Skip, the boy she took to the amusement park. Kelly told Skip that the gun he held was a "real gun," but she never told Skip to "put the gun down." When Skip fires, as is the case with "blank" bullets, the revolver does not recoil.
Kelly asks Korbin to call the Townsend Agency, but a moment later she calls Gail. That means she could have called the Townsend office directly herself from the phone in her hospital room. She also later asks the cab driver to call Townsend, which also would have been unnecessary if she called from the hospital room.
