Taylor Sheridan's Landman introduced a major death, a potential cast exit and more - but what questions still need answers in season 3? During the season 2 finale on Sunday, January 18, Cooper (Jacob Lofland) convinced Ariana (Paulina Chávez) to report her sexual assault to the police. This turned into Cooper being questioned after it turned out that man died from a heart attack once he was taken to the hospital. Once Cooper's dad, Tommy (Billy Bob Thornton), caught wind of the situation, he made sure his son wouldn't be charged.
