Horrifying or not, the demon's successful plan to trick Owen into setting it loose on the city.
In the third movie, Clara kicking the infecteds´ asses with a chainsaw and a couple of well delivered kicks and blows. All of it while dressed as a bride.
In a way, the policeman and the health inspector both averting the usual Zombie Infectee trope. The policeman, as soon as he's aware that he was bitten, tells his companions to scram while he stays behind with the infected Jennifer. The health inspector calmly (for the situation, anyway) finds a room with a sliding barred door, informs the rest of his condition, and then locks himself inside. It takes alot of guts to seal oneself in ones own prison like that.
