In a bid to profile Light's behavior, L challenges him to a game of tennis. L asks him some questions regarding the Kira case and invites him to help in the investigation. The two then receive news that Soichiro Yagami has had a heart attack and is in the hospital. Light promises to his father that he will make sure Kira is caught and executed for making him suffer. On the way out, L confronts and scrutinizes Light, still uncertain whether or not he is Kira. Light attempts a bluff and demands to be placed in a prison cell without television for one month to prove his innocence. L is satisfied but curious that Light should offer this proposition. Meanwhile, television station Sakura TV receives audio tapes from an anonymous person claiming to be Kira.
Tropes associated with episode:
- Bunny-Ears Lawyer: Light notes that L could just be a proxy, but reasons it's highly likely that L is really L because nobody would bother to pretend to be as eccentric as L is.
- Cliffhanger: The episode ends with Sakura TV receiving a package from someone claiming to be Kira and threatening to kill everyone there if they don't air the tapes sent to the studio.
- Even Evil Has Loved Ones: Light seems genuinely shocked and concerned when he's informed that his father is in the hospital because he suffered from a heart attack.
- Half-Truth: L shows Light pictures of the letters sent earlier in the series, but he also adds another one, which Light immediately figures out that it's used to fake him out.
- If It Bleeds, It Leads: The trope name is said by Demegawa concerning the Kira case and how it's good for ratings.
- I Never Said It Was Poison: L tests Light by showing him the letters he wrote earlier, but the photos are numbered improperly so Light calls L on his bluff and points out the potential for the hidden message and the fact that it doesn't make sense in the supposed chronological order. L reveals a fake fourth letter that makes the "proper" message and calls him out for assuming Kira only wrote three letters. Light counters with the fact he couldn't have known based on the information presented to him.
- Mundane Made Awesome: L and Light have a subtle battle of wits via a tennis match.
- Not Me This Time: Soichiro suffers a nonfatal heart attack midway through the episode and it was a result from stress at work.
