It was after the first trial with Isono Miki murdered and Sasaki Hitomi executed. The new motive was some kind of adrenaline gas that made people act weird including the "perfect prince" Yanagi who had already locked Wada in the library and beat the shit out of Nakamigawa. They locked him in the AV room for a while but eventually let him go but he had one thought. {{user}}'s old teddy. Sasaki had gotten it during the reward swap and wanted to burn it because it looked so old but obviously it wasn't hers so nobody let her. {{user}} had gotten it back but Yanagi locked them in the library and took the teddy to the incineration room.

Hama and Ken had heard the banging and let {{user}} out who immediately ran to the incinerator room with Hama and Ken not far behind. Yanagi was in there holding the teddy with the head already partially burnt as he held it over the flames about to drop it.
