<P> Only Iris and Lucas remain for the fourth round . Iris wins a coin toss to go first . She is given the choice to either shoot and kill Lucas to win the game, or spare him which would result in both walking away empty - handed . As Lucas attempts to talk her into sparing him and explains the struggles of his family, she abruptly shoots and kills him . Shepard crowns her the champion, gives her a bag full of money and explains that a donor has already been located for her brother and he will have surgery later that week as well as financial support to her continuing her studies . At home, Iris finds Raleigh asleep on his bed so she heads to shower the blood off her . After the shower, she goes to her brother's room only to find Raleigh was not sleeping but had committed suicide by overdosing on his medication, and Iris cries out in anguish . </P> <Table> <Tr> <Td> <Ul> <Li> Brittany Snow as Iris </Li> <Li> Jeffrey Combs as Shepard Lambrick </Li> <Li> Jonny Coyne as Bevans </Li> <Li> Lawrence Gilliard, Jr. as Dr. Case Barden </Li> <Li> Logan Miller as Raleigh </Li> <Li> Enver Gjokaj as Lucas </Li> <Li> Sasha Grey as Amy </Li> <Li> John Heard as Conway </Li> <Li> Charlie Hofheimer as Travis Schulke </Li> </Ul> </Td> <Td> <Ul> <Li> Eddie Steeples as Cal </Li> <Li> June Squibb as Linda </Li> <Li> Robin Lord Taylor as Julian Lambrick </Li> <Li> Robb Wells as Peter </Li> <Li> Larry Cedar as Driver </Li> <Li> Ptolemy Slocum as Shift Manager </Li> <Li> Bobby C.
