On opening night, Ocean institutes the final part of the plan by having FBI agents on his payroll arrive at the hotel and arrest Livingston Dell on suspicion of rigging the card-shuffling machines, allowing them to be replaced with actual rigged ones. Another FBI agent arrests Linus for switching the diamonds with fakes. The agent takes Linus away but reveals himself to be his father, Robert Caldwell, also in on Ocean's plan. They try to evacuate from the roof but are intercepted by Toulour, who takes the diamonds and parachutes off the roof. However, Ocean anticipated this, and never had Linus make the switch. Linus and his father escape in a helicopter piloted by Basher, tearing the case from the roof and taking the diamonds with them.
