Case File Synopsis
In Iris's Somnium, Date saw video footage of four women being murdered. They were the victims of the Original Cyclops Killer. The figure that slaughtered the four women looked like Date. Which means...
Date questioned Iris about this. Despite what was seen in the Somnium, there was not enough evidence to hold Iris and she was released.

Story Summary
ABIS HQ, Sunday

Date discussed what he had seen in the Somnium with Boss and Pewter. They confirmed that he had seen the victims of the Original Cyclops Serial Killings. Date was concerned about why his face appeared in the killer's reflection, but Boss assured him it meant nothing. Pewter told Date he believed there was no link between the Original and New killings, and could not identify the red figure or explain why these events appeared in Iris's Somnium.
Psync Room, Sunday

Date asked Iris what she knew about the Original Cyclops Serial Killings, but she said she had only heard about them on the news. After questioning her, Boss and Pewter asked Date to take her home, as they did not have enough evidence to hold her.
Driving, Sunday

While Date drove Iris back home, Iris asked him to stop at Marble before going home, so she could talk with him about something. Date agreed, and headed towards Marble.

Ota was waiting inside Marble. He told Date that Mama had stepped out and asked him to watch the bar.

- During the investigation segment in the Psync Room, examining the "CRT TV" will have Aiba mention that Videodrome will play soon, asking to turn on the TV. Videodrome is a 1983 American horror film, in which the CEO of a television station watches a TV program that shows the horrific murders of several people, eventually brainwashing him. This references has thematic connections to the events of this scene, as Kaname Date just finished experiencing Branch B of the Somnium PSYNCIN' IN THE VaiN, where he witnesses the brutal murders of the 4 Original Cyclops Serial Killing victims displayed on CRT TVs.[1]
