Synopsis
Kuwagata returns Teru's corsage, while affably dismissing his employer, Kazuki Morizono. As he walks past Kurosaki, Kuwagata inquires if Kurosaki remembers what side he is on, which deeply unsettles Kurosaki. Though Teru notices, she does not to press the issue at the moment and they leave the cruise ship to reunite with their friends.

Everyone celebrates at Rena's house for a job well done. As Rena cooks the food to thank everyone for saving her, she confesses to Kiyoshi that the experience has helped her realize that she needs to take responsibility to change herself rather than relying on others. At the party, Kurosaki reveals that Morizono has been arrested to investigate his illegal activities. However, during the interrogation, Morizono is unable to provide any information on Antler or "M's Testament" and continues to assert that Kuwagata had been behind everything. When Andou brings up Akira and Chiharu Mori's unexpected appearances on the ship, Kurosaki drops and breaks a glass. Riko decides that Kurosaki is too drunk to think straight and orders Teru to take Kurosaki home.

At Kurosaki's apartment, Teru admits that she noticed that Kurosaki has been upset each time Kuwagata is mentioned. Though Kurosaki has no proof, he believes that he has met Kuwagata before, when he was using the alias "Nagano" and had pressured him into recreating the Jack Frost virus during his employment at Kenbashi Electronics. Teru comforts and reassures Kurosaki that she wants to stay by his side and help him and reminds him of all their friends willing to do the same.
