I know theres four in the gang, but Marissa&Ryan are the main characters to me, and killing off Coop will not make the ratings higher (thats what they want). Without her, theres really no reason to watch anymore, and I'm sure many others will agree with me. The ratings will go down. We're all gutted - the start of season four has already been writen, I know, but bring her back in a coma, whatever, just don't kill her off for good.
