Last night, Audrina's family went to a gun range because, of course, it's not enough just to put braindead, emotionally excitable people on TV, you have to put guns in their hands, too.
And it turns out Audrina's mom Lynn is a pretty good shot. Which should come in handy for the post-apocalyptic hellscape she thinks she may have to survive.
Yeah, last earthquake she was in, she had to stab her way to safety. With a gun, she'd be much more efficient at killing looters who inevitably turn out to be just her house-cleaning staff.
