As part of his plan, Light relinquishes possession of Misa’s Death Note and allows Rem to fly off somewhere. He also buries his own copy of the Death Note in the forest, but Light makes it clear to Ryuk that he doesn’t want to give up his own Death Note until the next time that he utters the words suteru (give up). Meanwhile, with her memories of the Death Note and the Shinigami gone, Misa now thinks that she’s being held by a stalker. L is confused at this change in behavior because how she was acting earlier matched what the Second Kira would have done. In his interrogation, L brings up how she had been asking to be killed, but Misa doesn’t remember about any of that anymore. L then gets a phone call from Light, so he tells Light the hotel room they’re in.
When Light arrives, he confesses to the group that he is probably Kira. Light’s father Souichirou is shocked to hear his son say something like this, but Light feels that if L thinks he’s Kira, then he probably is. Indeed, L is now almost certain that Light is Kira, but he’s not sure what Light is trying to do by admitting this. Light goes on to say that the evidence points to himself and suggests that perhaps he’s unconsciously Kira. Perhaps when he goes to sleep, another side of him emerges and kills the criminals as Kira. L, however, immediately dismisses this theory because they had set up those cameras previously to watch Light and had seen him sleeping normally. Still, that didn’t lead L to conclude that Light isn’t Kira.
Trying to back up his unconsciously-Kira theory, Light reveals that he actually felt that it would be better if criminals died. Matsuda tries to make it sound normal that he might feel this way and cites the surveillance as evidence that Light can’t be Kira. Aizawa, however, disagrees because there could have been times when Light was away from home during which he could have done the killings. Knowing that Light could prove himself innocent if he were imprisoned and the criminal deaths stopped, L decides to lock him up. Light’s father starts to protest, but Light is ok with it in order to find out if he’s really Kira. Soon after Light is put into his prison cell, Light’s father asks to be removed from the investigation because of his personal feelings. When L won’t let him, Souichirou suggests that L imprison him too. For Souichirou’s sake, L agrees to do this.
As the days go on and Light stays in prison, the deaths of criminals stop. L had actually expected them to continue and is now confronted with the question of whether Light was consciously aware of being Kira. Light’s father is actually taking imprisonment worse than Light is, but he refuses to leave until he can do so together with his son. It is not until the seventh day, when L asks if Light is ok, Light answer includes the words suteru. This signals to Ryuk that Light is ready to relinquish his Death Note, so Ryuk leaves the cell. And just like that, Light suddenly loses his memories of the Death Note and the Shinigami. He now starts to protest that he’s not Kira and wants to be let out, but L isn’t about to let that happen.
On the 15th day of Light’s imprisonment, the newspapers start reporting that two weeks worth of criminals were all killed in one day. Upon learning this news, a haggard Souichirou realizes that the suspicion on his son should be gone, but he also knows that L wouldn’t immediately feel this way. L prevents Matsuda from telling Light about this and instead asks Light to confess that he’s Kira. Without his Death Note memories, Light now believes that everything is a trap and tries to get L to see that his eyes aren’t the eyes of a person who’s lying. And since Misa’s apparently only knowledge of Kira is the ally of justice who avenged her parents, L is at a loss for what’s going on.
I find it really amusing how different Light is after giving up his Death Note. His entire look is in those eyes, and they completely lose the evil vibe after his memory gets wiped. I’m too used to Light being shrewd and conniving that the deer-in-the-headlights look just doesn’t suit him.
I remember back when I was reading the manga that I was completely confused as to how giving up the Death Note would solve Light’s problems. In retrospect now that I know what’s going to happen, everything makes more sense. What better way to confuse L into thinking that you’re innocent than by truly believing that you’re innocent.
Next week, we’ll find out what happened and how the killings are continuing without Light and Misa.
