Landman has had its fair share of shocking moments, but fans couldn't have predicted the show's latest breakup. During the Sunday, November 16, episode, Ariana (Paulina Chávez) pulled the plug on her romance with Cooper (Jacob Lofland) after spending hours worrying about his safety when his phone died at work. Still in mourning, Ariana told Cooper - who just hit it big at oil wells - that she can't go through another loss like the death of her late husband, Elvio.
