Who's da New King of Hell? - S4-E10
Continuity mistake: When Lucifer, as the Devil, tells the demons to go home, all the bodies fall down. We see the bodies fall down behind Chloe, too. After the shot of the Devil, the camera goes back to Chloe and the bodies all fall down again.
Expire Erect - S4-E5
Continuity mistake: Near the end, as Dan says "this is all on me", in a shot from behind her Maze is spinning her knife then stops, gripping it pointing downwards in her fist. Cut to a new angle and her hand is instantly turned over, with the knife sticking out sideways.
Answer: Yes and no. After the body dies, it loses about 1.5°C per hour until it reaches ambient temperature (i.e. the temperature where the body is found). But there are factors affecting the rate of loss, and one has to assume a starting temperature of 98.6°F. In this case, after factoring in the time from when the police were called to when the body temperature was checked, it would have been determined some time had passed, just not a lot, before Beth saw Moira standing over Megan. Really, what they were saying is Moira's story is believable: that she found her sister dead and picked up the hammer right as the garage door opened.
