The team next tracks Sloane to Mongolia and the tomb of Milo Rambaldi. There Sydney encounters Sloane yet again as he implements his endgame by placing the Horizon on an altar, thus creating a red, hovering ball-shaped fluid similar to that created by the Mueller device. Sydney disrupts Sloane's plans by grabbing the Horizon from the altar, causing the ball to collapse in a torrent of red liquid. Sark leads Jack and Vaughn into the tomb after capturing them, and Sloane shoots Jack in the chest to force Sydney and Vaughn to leave. Seeing her father severely wounded, Sydney grabs a gun and eventually shoots Sloane several times, who crashes into the puddle of Rambaldi-fluid. With Sloane seemingly dead, Sydney tries to stay with her bleeding father, but he begs her to leave him and to stop Irina. Sydney reluctantly obeys and departs for Hong Kong for a final confrontation with Irina. Jack drags himself back into the tomb and confronts Sloane, who has become immortal because of the fluid. Sloane offers to heal Jack, but Jack tells Sloane that he has caused so much pain for Sydney over the years that he will not allow him to do it again and reveals a bomb that he strapped to his body and detonates it, killing himself. The explosion causes a cave in and Sloane is trapped in there forever.
