[Note: The dates of the 10/3 and 10/7 for the Yotsuba meetings I was able to reconstruct from what the characters said. However, the police must have called off the Kira case before October, even though the event occurs in the manga after Raito shows L information about Yotsuba, which takes place in October, according to the translation I have. This nonconformity is somewhat confusing, but everything still is in chronological order according to the manga]
