In "Game Night", Nick kidnaps the prophet Donatello Redfield and claims to have injected him with thallium. Nick resists the Winchesters' attempts to get him to reveal Donatello's location and enjoys taunting them. Finally, he agrees to lead them to Donatello while Jack discovers that Nick injected Donatello with angel grace, not poison. Nick explains that he used Donatello as a conduit to communicate with Lucifer in the Empty and intends to bring him back. Nick bashes Sam's head in with a rock, leaving him severely injured, before fleeing to an abandoned cabin to perform a spell Lucifer gave him using Jack's blood. Nick succeeds in bringing Lucifer back from the Empty, but is interrupted by Jack and Mary. Jack sends Lucifer back to the Empty and causes Nick to burn up from the inside, killing him before healing Sam's injuries. Nick's body is later found by Sam and Dean in "Absence." Sam covers up Nick's body with a blanket, but it is apparently otherwise just left in the abandoned cabin. Despite wanting Nick dead, Sam is horrified by the brutal manner of his demise.
