Light's mother and sister welcome you into his home; Light, who is also present, greets you politely but cautiously. By speaking to the three of them together, perhaps you can learn more about Light's relationship with his family.
Light's bedroom is upstairs, if you'd like to take a look around.
The television in the living room is on, showing a performance of something called Death Note: The Musical, which would probably raise a lot of questions if you knew what a Death Note was.
Light's mother asks if you'd like an apple. When she checks, though, the fruit bowl is empty. Apparently the apples have been disappearing at a surprising rate lately. It doesn't seem relevant to the case, but you could think about who's responsible.
Or would you prefer to go somewhere else?
