The Replacement

S4, E1: In Florida, Tom surprises the girls with some news: he's bringing in his friend Dynamite to help with the workload, and Krystal and Lea are forced to hunt alone with a sluggish vehicle and unfamiliar dogs. Their frustration grows, but they show the boys they can handle it. In Texas, it's new girl Katie's first day on the hunt, and Jerry's "new and improved Krystal" hobbles her first hog. But with Jerry is flirting up a storm, Robert is feeling pretty stormy himself--he thinks that Katie is just another distraction, and that her days are numbered.
