If you were actually in this situation
If you were the cameraman, and you were in this situation with Jennifer's character, how long could you stand her over-dependent, whiny, screeching mentality, before you knocked her unconscious, threw her over your shoulder, threw the camera down and run around killing every zombie you could find??
She was gonna get them both killed with that screaming and bellowing. Who couldn't miss that? The zombies in the lobby heard her.
I know it's wrong to hit a girl, but how many people actually come, face to face with this kind of horrible stuff??
