It's been a while since the start of the Kira case. The task force is working with fast pace trying to figure out who kira is, ignoring as always L's suspicions about Light yagami being Kira. This is helpful for Light of course. Light is very busy satten down on the sofa next to a 8 year old child, trying to help with math homework. This child brings L more suspicions since Light never really explained how he found this little one.
