Bride of Chucky (1998)

Plot hole: In the end of the film it is heard the police want to exhume the body of Charles Lee Ray from his grave site in New Jersey. Now when Chucky and the crew get to the grave site they find and kill a coroner who is digging up the body. He is the only one there at 1am, by himself, a lonely coroner without any police officers, after all this is a police investigation and I doubt the cops would have him there alone. Then right at the end the Detective who is hunting them arrives. Now he is a cop from Lockport, about six states away. A. Why did he drive all that way to see the body? B. A cop from all the way down there shows up but no new Jersey cops are at the scene?

Tiffany: Oh, Chucky look at us. We belong dead. Good bye darling, I'll see you in hell.

Trivia: The "Voodoo for Dummies" book Tiff reads was a prop made for the movie. The apparent author is Don Mancini, the script writer. There is however a "Complete Idiot's Guide to Voodoo".

Question: If Tiffany was pregnant, why didn't she have a bump?
