Impertinence

 Impertinence is the forth chapter of Volume six and 47th chapter overall.

Plot
Even though touching only a piece of the notebook won’t bring back her memories, Misa can now at least see Rem, and she can explain what’s going on. Rem tells Misa that Light is Kira and that she was once an owner of the Death Note. She tells her that Light’s plan was to work with L in catching another Kira after gaining his trust by losing all memories of the Death Note. Then, after Kira is caught, he will touch the notebook and gain all of his memories once again. Rem also tells Misa that he is willing to help Light with his plan if it’ll get the Death Note out of the hands of the vile current owner. He cautions her to be careful around the Yotsuba Group since they are willing to kill her after they have used her.

Misa leaves the bathroom and goes back to the room where she is being interviewed.
