The scene then cuts to Near and Mello discovering L's death, with Mello declaring his independence. Four years later, Near is about to leave Wammy's House, and a flashback occurs, adapted from the Death Note One-Shot Special manga chapter, where L speaks to the children at the orphanage before investigating the Kira case.
