Potted Plant

 Potted Plant is the sixth chapter of Volume six and 49th chapter overall.

Plot
If the killings stop, then the team can conclude that Higuchi is Kira. However, L and Light realize that without Higuchi showing how he kills as Kira, then arresting him will be meaningless. Nevertheless, Light tries to convince L to capture Higuchi now and try to figure out how he kills once he’s detained. L says that he needs time to think it over.

Afterwards, L calls Wedy and orders her to focus her spying solely on Higuchi. He orders her to install cameras and listening devices in all of Higuchi’s cars L asks Light if he hypothetically was Kira and the powers can be passed on from person to person, does he think that it was because of Light’s will or the will of someone else working behind the scenes. Light concludes that it would probably be his will to pass on the power because if another person was in control, they would not have waited until after Light was captured.

L says that their task now is to find a way to make Higuchi show them how he kills without transferring his powers to someone else. L figures out a plan in which Matsuda will go on Sakura TV and threaten to reveal the identity of Kira. Higuchi will remember Matsuda as the nosy manager of Misa Amane who might have overheard the conversation inside the Yotsuba meeting room. Higuchi will try to kill Matsuda, but then realize that he has been given a fake name. Higuchi will call Misa and Mogi. Then, he will try to call Yoshida productions where the manager will tell him that his resume, which is in the Yoshida productions office, contains his real name. Higuchi will then have no choice but to show his method of killing, which will be caught by the cameras set up by Wedy.
