The episode continues immediately after the last one. Light and Mikami are both shocked that no one has died after 40 seconds. It is then that Near reveals that Mikami's notebook had been replaced by a fake the SPK created and since Light's name was the only one not written, Light is exposed as Kira.
Out of options, Light confesses to being Kira and attempts to acquit himself by justifying the reason why he used the notebook. When that fails, he attempts to convince Near that the notebook the task force brought with them was fake, which is used as a distraction so he can write down Near's name on a piece of the Death Note hidden in his watch. This plan is foiled when Light is shot several times by Matsuda, the latter angry that Light did not care about his father's death.
Moments later, Mikami stabs himself and he quickly bleeds to death. Mikami's suicide creates a diversion, allowing an injured Light escape the warehouse. Near suggests that the task force to not go after Light, as it is unlikely he has other hidden pieces and his wounds will probably stop him soon, but Aizawa decides to go after him anyway.
As Light runs away, he hallucinates passing a younger version of himself without the notebook. Ryuk, from atop a tower, reminds Light that he would be the one to write Light's name in his notebook. When Light, possibly out of exhaustion, decides to hide in another warehouse, Ryuk writes Light's name down, killing him. Light dies halfway up a flight of stairs, which possibly symbolized that he couldn't go to heaven nor hell.
