Usually female killers do have man hands because the writters start the storyline, play it out as long as they can, and then give you the big shocker when it starts to fizzle. Think about Vincent Izzary's charachter (David); he last shot scenes in late October and he last air date was end of November, early December. They had to start taping this in November because it first became a mistery right around the holidays, and they'll drag it out as long as they can. If they intend to have Greenlee as the killer, she has to be recast and then the episodes taped. If it's that obsessed Kenny guy then it should wrap up soon - but even if it's Kenny, it leads right into another storyline about... You guessed it, Zack.
