Summary

Egon Weisbach was one of the first investigators in the murder of the Liebert parents. On his last day on the job before retirement, he is escorting a convicted serial murderer but wants to know why he killed someone who did not fit his modus operandi. At the same time, Dr. Gillen is interviewing several murderers wondering why they killed someone who also did not fit their usual targets. Both realize that all these criminals committed murders outside their usual scope at the request of a young man, presumably Johan.

What happens in this episode

This installment advances Monster through investigation, consequence, and character pressure rather than disposable filler. PopRot is using the structured episode title/synopsis data available for this entry and rewriting it into original wording, so this recap intentionally avoids unsupported scene details when the source summary is brief.

The practical viewing takeaway: track which characters gain new information, which past decisions resurface, and how Tenma’s moral burden changes after this chapter.
