第 22 集: Finn Clarke 前往 Revonland，透過錄音帶揭開母親 Mariel 的過去。
A young woman named Finn Clarke travels to Revonland in the Arctic to learn more about her mother who died after giving birth to her 16 years ago to the day. She stays with Daniel and Anna who had watched over her mother, Mariel, after she suddenly left for America. Using her mother's diary and pictures, Finn learns that in high school, Mariel had a crush on a football player named Sean and dated another boy named Allen. She finds some cassettes recorded by Mariel and decides to reveal them publicly as a webcast called "Finn's Room" which are heard by both Lupin and Mattea. The tapes reveal that Mariel split with Sean and became pregnant with Allen, with Tomoe using hypnotic suggestion to make her believe they were always close to each other. The final tape reveals in a call with Sean that Allen had assaulted Marie, with surveillance footage at the time showing the two boys arguing and then being shot by another of Tomoe's "students", who then kills herself on her instructions. As Finn goes into shock, Lupin rushes in and consoles her, while wondering about Tomoe's motivation. As he leaves, he encounters Zenigata, who is in pursuit of Mattea. (Source: Wikipedia)
