Scream endings

[Screamfreak]

I'm very confused. Who were the killers in S2 and S3 in Kevin Williamson's outline??
Which was the alternate ending for S3?
Who were the alternate killers in S2?

Sreamfreak, Kevin Williamson never actually wrote a Scream 2 outline; at least not that know of. HIs original script, though, had Derek, Hallie, and Mrs. Loomis as the killers.

As for Scream 3, all I know is that one alternate killer sequence had Gale and John Milton being the killers.
