What's the end game with Sam? (SPOILERS)
They're playing up this whole thing with her possibly becoming a killer, with Billy being her dad and when she kills she goes frantic and seems to really enjoy it.
Surely they'll not actually make her one of the Ghostfaces in a future sequel? It would be very unusual to build up a 'final girl' only to make them the baddie in the end.
If they're not going to do that then I'm not overly sure what the point of the whole character arc would be. Just a big tease and fakeout? Character development, to make her a complex character who has some homicidal urges deep down but will ultimately over come it?
