While Kat's interview was going on in the room next door, and mostly consisted of Kat trying to cause as much chaos and heartache for the questioner as possible, Kamiko's was taking a very different route.
What neither had realised, is that both of them had been investigated slightly during their first three days of their punishments. This led to them trying to set up the most 'ideal' environment to get information out of them. It was… not working all that well for them when it came to Kat, but Envy felt somewhat justified because the just couldn't find much on her, thinking she was a very private person.
