During the credits scene, Misa Amane is shown standing on the rooftop of the old Task Force building, behind the safety rail. According to Death Note /A Official Analysis Guide of the Animation, her fate is left to the viewer's interpretation.
This and the previous episode are the only two to be rated TV-MA.
Anthony Rester, whose real name is "Anthony Carter", has his name written as "Anthohy Carter" in the fake notebook. If Light Yagami's plan had succeeded, he would have been the only one other than Light who would not have been killed.
