As an April Fool's joke on the crew, producer/director Jon Cassar revealed this fake ending to this episode. Palmer's press conference ends and he goes down to his limo. He gets in successfully and rides off. After a while, we find out that someone is sitting next to him. That someone is Nina Myers. We realize that Palmer was in on the whole thing. We then shift to a scene in the desert. We close in on a parachute, then pan over to reveal George Mason, who jumped out of the plane before the bomb exploded. The end.
An additional scene was filmed, but never really intended to air. It is additional footage of Max after Mandy's call. A woman places her bandaged hand on Max's shoulder. He whispers something to her, then she bends down to kiss him. It is then we realize the woman is Nina, who has been behind it all along. They cut it because they realized they couldn't possibly explain it given the show's time frame.
The resolutions to many of the storylines from the finale of Season 2 were never fully wrapped up on the show. However, the 2006 release of 24: The Game (2006) for the PlayStation 2 did in fact answer many questions, including who was behind the attack on Palmer's life.
