Decision

Light decides to tell L that he thinks that he may be Kira subconsciously and wishes to be confined. Light’s father also believes it is a good idea that he himself be confined to a cell as he cannot risk his emotions getting the better of him in this investigation. Light concocts a plan whereby he tells Ryuk he will relinquish ownership of the Death Note at any time in a discreet discussion, while being monitored by L. After Light’s imprisonment, Kira’s executions stop and L’s suspicion is heightened. Light chooses this time to give up the Death Note, ensuring he will lose his memories of being Kira. His change in behavior puzzles L; Light goes from being calm to completely desperate. The Kira executions then resume and the new spate of killings confuses L.
