Dewey's a very lucky man, or he's a very good killer.  In the two movies, we never see Dewey and Mr. Ghostface, never.  It is just a coincidence?  I don't think so, but for more about this theory, just go to the Dewey Riley 3rd killer theory section.  Anyway, Dewey get stabed in the back at the end of the first movie, that's why he's got a bad limp in Scream 2.  He also gets involved in a private meeting (two times) with Mr. Ghostface, the first time he lets the killer go out or help the killer to escape of the Ometa Beta Zeta sorotiy house and the second time, he gets stabed again in the back, trying to protect Gale from Mr. Ghostface.  Everyone tough that he was killed, but he survives to that stab again and he'll be back in Scream 3 for sure.
