This was the perfect end to an absolutely rubbish series. I don't know what happened to the writers during this season, but the story;lines became increasingly contrived as it went on, culminating in this final episode which was either written by a 12 year old, or ad libbed by the canteen staff. "Oh yea right, but then it turns out there's a serial killer, and he kills one, but big strong <spoiler-alert> gets him in the end." Would he fXXk if it were a real serial killer. Bah! I'm glad this sXXt-pile is finished.
