But as fans learn, his heart (and maybe his motives) are a little harder to read.In last week’s episode, things got messy. Mickey’s daughter, Skye, has become the prime suspect in her boyfriend Brandon’s murder, forcing Mickey to take a step back from the investigation. Dawson offers to risk it all to help her. In TV Insider’s sneak peek, Mickey is seen driving when a text from an unknown caller warns her to check her rearview. Turns out, the car following her is Dawson. "I can’t do this right now," she snaps. But he insists on helping. He’s heard about Skye’s situation and wants to use his DEA connections to track down who’s really behind Brandon’s death. But Mickey isn’t so sure."It would totally blow your cover," she warns. “Let me worry about that,” he says. But the trust between them is now fractured. "You spent an entire year building your case, completely cut off from all your family and friends," she reminds him. “Not everyone,” he replies.Executive producers Tony Phelan and Joan Rather teased that Dawson and Mickey’s relationship will become a "central part" of Sheriff Country.Wes Chatham's roles before Sheriff CountryAre Wes Chatham’s looks and intensity nagging you?
