Silence

Silence (沈黙, Chinmoku) is the twenty-fifth episode in the anime Death Note.

Synopsis
L continues to ask Rem about Death Notes, but she continues to reveal as little information as possible in order to avoid implicating Light or Misa. Meanwhile, Misa begins to use her Death Note to kill criminals and moments later, L suspects Misa, but Light denies her involvement. L wonders if a piece of the notebook could bear the same effects of the entire notebook, but realizes that the fake Death Note rules still maintain Light and Misa's innocence. Overhearing Light and L's conversation, Rem wonders why Light would put himself and Misa in danger again and then realizes that it was part of Light's plan to do so in order to entice Rem to kill L.

Later, Light finds L on the roof of the task force headquarters with the latter lamenting about how distant he is from other people. The two of them converse and realize how often they, like most people, lie. When both of them return to join the rest of the task force, L reveals that he is planning on testing the fake 13 day rule by having a condemned criminal write in the Death Note. Before L can go through with the plan, Rem kills Watari who presses a button setting off an alarm and wiping the headquarters hard drive, then she kills L. This in turn kills Rem, whose body is reduced to dust. After secretly snatching away Rem's notebook, Light claims to the task force that he will avenge Watari and L by solving the case. With everything standing in his way gone, Light silently declares himself "god of the new world".

Trivia

 * There are several anime-exclusive scenes in this episode. The first depicts Misa performing killings while singing a song dedicated to Kira. The second is the aforementioned confrontation between Light and L in the rooftop. The last newly added scene is of L rubbing Light’s feet before joining up with the rest of the task force. In this particular scene, L implies that he knows of his imminent death by lamenting to Light that the two of them “will be parting ways soon”.
 * This and episode 26 are the only episodes not to include an eyecatch featuring one of the Death Note rules.
