Yeah I know what you mean it just disappears, it's the same with the scripts in Scream 3 after Gale asks "who dies next" and Jennifer says "You do" it's never brought up again, despite Dewey mentioning that there were multiple scripts "something about trying to keep the ending off of the internet". The killer does rewrite the script during the scene but they could have still checked every script to see if he carried on after a brief rewrite.

As for the plot point in Scream 2 it's as if the killers in Scream 2 had the same idea as the killers in Scream 4 where as the killers in 2 called themselves copycats the ones in 4 were rebooting the original surely the idea used in 2 would have been better in 4?

That would work. They already returned to woodsborrow and had Sidney. Add in Gale and Dewey finally succumbing to fate with Sidney being the killer would've been an epic way to go out

At one point in the film, Gale and Dewey make the observation that the killer is killing people in a duplication of Woodsboro, going so far as to choose victims with the same names. What happened to that plot point? It certainly doesn't explain the order or the selection of the rest of the victims in the movie. Yes, Randy's murder by Mrs. Loomis and its motive was obvious, but what about the others?

The murder of Randy was not planned and meant they had to change their plans as Sidney went into hiding. That's why they already went after her and Gale that evening.
