Scream - presented by Sara.

It’s like the movie (Stab) in Scream 2 was based on the actions of Scream 1. Scr3am was filming Stab 2 (the movie from Scream 2), which mentioned the original murders from Scream 1 and Stab: the original (which was the movie being filmed in Scream 2). 

And Scre4m is about the killer recreating Stab: The Original (the movie from Scream 2) in which the killer was creating Scream 1’s original murders. 

Oh and all bets are off.
